Introduction This introduction is not part of IEEE Std C37.06-2009, IEEE Standard for AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis—Preferred Ratings and Related Required Capabilities for Voltages Above 1 000 V.

This standard is a revision of ANSI C37.06-2000. It reflects changes needed to coordinate with the final wording contained in the defining IEEE Std C37.04-1999 and corrigendum, IEEE Std C37.04a™-2003, IEEE Std C37.04b™-2008, IEEE Std C37.09™-1999 and corrigendum, IEEE Std C37.09a™-2005, IEEE PC37.09b™ (Draft 3, September 2009), IEEE Std C37.01 0™-1999 0™-1999 and IEEE Std C37.010-2005, and other international standards such as IEC 62271-100:2008 [B5]. [B5]. a, b ANSI C37.06-2000 and the earlier editions were prepared by working groups sponsored by NEMA. In January 2003, NEMA transferred responsibility for ANSI C37.06 to the IEEE Power & Energy Society Switchgear Committee. IEEE Std C37.06 is now the responsibility of the High-Voltage Circuit Breaker Subcommittee of the IEEE Power & Energy Society, Switchgear Committee. This introduction summarizes significant substantive and editorial changes between this revision and the 2000 version. It also comments historically on the changes made since the 1987 edition and the evolution of the preferred ratings standards. standards. This standard, IEEE Std C37.06-2009, identifies preferred ratings of circuit breakers and does not exclude use of circuit-breaker characteristics characteristics not identified in this standard. The major focus of this revision is to adjust the ratings tables to coordinate with the revised scheme for representation of transient recovery voltage (TRV). (TRV). The new TRV scheme has been defined and elaborated in IEEE Std C37.04b-2008, IEEE PC37.09b (Draft 3, September 2009), and IEEE Std C37.010-2005, and this revision brings ANSI C37.06-2000 into harmony with those documents. The manner of representing the TRV has been changed as p art of a major effort to harmonize with the TRV requirements in IEC 62271-100:2008 [B5]. [B5]. Accompanying this change in the TRV representation is the introduction of the rate of rise of recovery voltage (RRRV) ratings. The representation of TRV in this revision is harmonized with that in IEC 62271-100:2008 [B5]. [B5]. (A joint IEEE and IEC task force working group was established to solve the problem of TRV envelopes). The new TRV capability of circuit breakers according to IEEE Std C37.04b-2008 is described by two- or four parameter envelopes rather than the former “1–cosine” and “exponential-cosine” “exponential-cosine” envelopes used in previous editions of this standard. The two-parameter two-parameter method is used on voltages below 100 kV, and the four-parameter method is used at 100 kV and above. Comprehensive explanations of the two-parameter and the four-parameter methods are provided in this standard. The technical data of the tables remains very much the same, except that some ratings have been updated to reflect the requirements of the users. In particular, the tables now reflect a first pole to clear factor of 1.3 and 1.5 for effectively grounded and non-effectively grounded systems respectively. In order to keep the tables of reasonable size, it has been necessary to add tables with the data for the new representation of TRV values. These tables make the ratings easier to understand and simplify use during power testing. The tables provide the preferred values for the inherent (i.e., prospective) TRV. The tables provide the TRV values for 100% terminal faults faults (T100), as well as for for 60%, 30%, and 10% terminal terminal faults (T60, T30, T10), plus the short-line fault and the out-of-phase switching conditions. Many technical comments have been given in the text along with curves, or details have been listed explicitly in the tables to assist with a summary understanding of the phenomena involved. The explanatory information clauses for the tables are indicated in clauses that follow the tables. It is noted that according to a

the IEEE formatting, the Notes on tables are normative (mandatory part of the standard) and that Notes to the text are informative. Harmonization of voltages was begun with the adoption of 550 kV and 800 kV, replacing 525 kV and 765 kV respectively, in IEC. The transmission voltage classes of 121 kV, 169 kV, and 242 kV were changed to 123 kV, 170 kV and 245 kV (maximum voltages) respectively listed in ANSI C37.06-1997 to complete the harmonization of voltages with IEC. New symbols for the recovery voltage given in IEEE Std C37.04b-2008 are used in this document, and the correlation between the new and the old symbols is discussed in the “Information” clause referenced in the footnote of the affected tables. The new symbols and TRV representation are in harmony with the revised IEEE Std C37.011™-2005. To facilitate use of the tables, the individual lines and columns have been identified with line numbers and column numbers. The TRV values have been revised to reflect the new representation of the TRV, but other key values have not been changed from the 2000 edition. Throughout this document, the term peak term peak traditionally traditionally associated with the maximum value of transient or periodic waveform is used. This continues the practice introduced in the 1997 edition, which substituted peak for for the previously used crest term. term. In an effort to harmonize with IEC 62271-series standards, new terms Class S1 and S1 and Class S2 are S2 are used to denote traditional terms as indoor or outdoor. The term Class S1 S1 circuit breakers is for cable systems (historical predominant use was for indoor circuit breakers) and the term Class S2 circuit S2 circuit breakers is for overhead line systems (historical predominant use was for outdoor circuit breakers). Definitions are included in IEEE Std C37.04b-2008.

General notes 1)

For the previous 1-cosine standard waveform envelope, the time-to-peak (T 2) value is equal to 1.138 times the ( t 3 ) parameter value listed listed in this standard. This is a purely mathematical mathematical translation to fit the new TRV representation. The actual TRV that the circuit breaker must withstand is essentially identical under the old system as in the new system. The restated TRV values are consistent with an amplitude factor of 2.0, namely for non-damped systems. The old envelopes were characterized by the time-to-peak value (T2) and its peak (E 2) was the focal point of the old TRV. In the new scheme, the parameters are (t 3) and (uc).

2)

The titles of the tables include the term prospective term prospective TRV to to emphasize that the TRV ratings are for the prospective (inherent to the system) TRVs that would result if unmodified by the interruption process either by the arc voltage, circuit-breaker capacitance, capacitors, and/or of any resistor insertion designed into the circuit breaker.

Specific notes on individual tables 1 is essentially the same as in Table 1 of ANSI C37.06-2000 edition for indoor Table 1 —The data in Table 1 is circuit breakers. It has been redesignated for Class S1 circuit breakers, those connected by cables rather than directly to overhead lines. The TRV data has been relocated to Table 2 2 and Table 3. 3. The historic voltage range factor K has been dropped, as it was eliminated from the rating structure in the 1999 revision of IEEE Std C37.04-1999. Circuit breakers designed and tested in accordance with the 1979 (or earlier) editions of IEEE C37.04-1999 and IEEE Std C37.09-1999, with a voltage range factor K greater than 1.0, should be applied in accordance with the older standards. The preferred ratings for such circuit breakers are shown in ANSI C37.06-1987.

Table 2 2 and Table 3 —These tables contain the expanded TRV data values for the new two-parameter method representation of TRV for circuit breakers rated below 100 kV. The old “rated time-to-peak” (T 2) values for TRV have been replaced by the new t 3 values in accord with IEEE Std C37.04b-2008. The values are harmonized with the values in IEC 62271-100:2008 [B5] and [B5] and are based on an amplitude factor of 1.40 for the T100 terminal fault. Table 2 2 includes values for T100 terminal fault and out-of-phase test conditions, while Table 3 includes 3 includes values for T100, T60, T30, and T10 terminal faults. Table 4 —This table presents the preferred capacitance current switching ratings for Class S1 circuit breakers applied to capacitance switching classes C0, C1, and C2, in accordance with IEEE Std C37.09a2005 and C1 and C2 coordinated with IEEE Std C37.04a-2003 and the revised application guide IEEE Std C37.012-2005. Table 5 —This table is similar to new Table 1, 1, but includes the preferred ratings for Class S2 circuit breakers, connected directly to overhead lines. In the 2000 edition, these circuit breakers were designated as outdoor circuit breakers. The values are unchanged from the 2000 edition, except that TRV values have been transferred to to new Table 6 and 6 and Table 7, 7, and restated in the new two-parameter method representation. representation. Table 6 6 and Table 7 —These tables contain two-parameter method TRV data reformatted in the same manner as Table 2 and 2 and Table 3, 3, except that the short-line fault TRV values for outdoor circuit breakers are added to Table 6. 6. The TRV values are based on an amplitude factor of 1.54 for the T100 terminal fault, as in the 2000 edition. Table 8 —This table presents the preferred capacitance current switching ratings for Class S2 circuit breakers (voltage classes below 100 kV) applied to capacitance switching for classes C0, C1 and C2, in accordance with IEEE Std C37.09a-2005, and coordinated with IEEE Std C37.04a-2003 and the revised application guide IEEE Std C37.012-2005 for C1 and C2 applications, with voltages rated below 100 kV. The Capacitor Subcommittee of the IEEE PES Transmission and Distribution Committee suggested updated values. Table 9 —This table provides preferred ratings for outdoor circuit breakers rated 100 kV and above. It has been modified in a manner similar to Table 5, 5, and TRV values have been transferred to new Table 10, 10, Table 11, 11, Table 12, 12, and Table 13. 13. Table 10, 10, Table 11, 11, Table 12, 12, and Table 13 —These tables contain revised TRV requirements for circuit breakers rated 100 kV and above. Table 10 and 10 and Table 11 include 11 include values for T100 terminal fault, short-line fault, and out-of-phase conditions using the four-parameter representation of TRV. The values in these two tables differ by the first pole to clear factor ( k pp 10 and 1.5 for Table 11. 11. Table 12 and 12 and Table pp ), 1.3 for Table 10 and 13 13 contain the corresponding values for T100, T60, T30, and T10 terminal faults, based on the four parameter method TRV representation representation for T100 and T60, and the two-parameter method representation representation for T30 and T10 terminal fault conditions. Table 14 —This table presents the preferred capacitance current switching ratings for classes C0, C1, and C2 in accordance with IEEE Std C37.09a-2005, and coordinated with IEEE Std C37.04a-2003 and the revised IEEE Std C37.012-2005 for C1 and C2, for voltages rated 100 kV and above. The Capacitor Subcommittee Subcommittee of the IEEE PES Transmission and Distribution Committee suggested updated values. Table 15 —This table presents preferred dielectric withstand ratings. It contains no significant changes from Table 4 in the 2000 edition. Lines 5, 7, 10, 12 were added to include the characteristics of some vacuum circuit breakers in service. The interrupter full-wave withstand was removed in the 1997 version, but reinstated (as a Note) in the 2000 revision. Also in the 2000 edition, the creepage distances were revised to coordinate with IEEE Std C37.010-1999. Table 16 —This table presents preferred dielectric withstand ratings for circuit breakers in gas-insulated substations, previously in Table 5 of the 2000 edition. Some ratings were added to represent what is

IEEE Std C37.06-2009 IEEE Standard for AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis— Preferred Ratings and Related Required Capabilities for Voltages Above 1000 V

1.3 Preferred ratings This standard provides preferred ratings for circuit breakers. IEEE Std C37.04™-1999, IEEE Std C37.04a™-2003, and IEEE Std C37.04b™-2008 contain the rating structure for circuit breakers. 1 IEEE Std C37.09™-1999 and IEEE Std C37.09a™-2005 [and IEEE PC37.09b™-2008 (Draft 3, September 2009) when published] contain the test requirements to support the ratings. Although this standard identifies preferred ratings, there are instances where a user must make a selection from several preferred or alternate ratings.

3. General applications to circuit breakers For service conditions, definitions, interpretation of ratings, tests, and qualifying terms, see IEEE Std C37.04-1999, IEEE Std C37.04a-2003 (Amendment 1), IEEE Std C37.09-1999 and IEEE Std C37.09a-2005, and IEEE Std C37.011-2005. Reference should be made to ANSI C37.06.1 [B1] for ratings of circuit breakers in special applications with fast TRV requirements calling for definite purpose circu circuit breakers with special TRV requirements and for circuit breakers in transformer limited fault applications.6 For other information not listed in these tables refer to the following: a)

Abbreviations used in the tables: RRRV = rate of rise of recovery voltage, TRV = transient recovery voltage.

b)

Voltage range factor K was defined in IEEE Std C37.04-1979 and is no longer defined. It is no longer part of the rating structure for high-voltage circuit breakers. In IEEE Std C37.04-1999, IEEE Std C37.09-1999, and ANSI C37.06-2000, the voltage range factor was effectively eliminated as it was changed to 1.0. For ratings of circuit breakers with voltage range factor K greater than 1.0, refer to ANSI C37.06-1987, and to the earlier versions of the relevant standards (e.g., IEEE C37.04-1979, IEEE Std C37.09-1979, ANSI C37.06-1987, IEEE Std C37.010-1979).

c)

The preferred ratings are for 50 Hz and 60 Hz systems. For applications at other system frequencies refer to IEEE Std C37.010-2005 for special considerations. The rated interrupting times and peak recovery voltage values and times given are all based on 60 Hz systems.

d)

The maximum permissible tripping time delay Y is 2 s or 1 s according to the voltage class.

e)

Short line fault in the text of this standard means single line-to-ground short-line fault. No references are made to the multi-line phase-to-phase short-line fault. Some three-phase line faults are not be covered in this standard. For discussion on this subject see IEEE Std C37.011-2005, 4.2.4.

f)

All tables show “prospective” or “inherent” characteristics of the currents and/or voltages. Here prospective values are used in conformance with international standard. The word “inherent” was used in many previous IEEE publications. These words have the same meaning in this standard. They indicate, for example, that the TRV in this standard is that given by the system. The circuit breakers, during interruption of the short circuit current, modify the TRV and the modified values are read on oscillographs during interruption.

Current values have generally been rounded to the nearest kiloampere (kA) except that two significant figures are used for values below 10 kA.

4. Basic definitions applied in this standard Definitions applicable to this standard are contained in IEEE Std C37.04-1999, IEEE Std C37.04a-2003, IEEE Std C37.04b-2008, IEEE Std C37.09-1999, IEEE Std C37.09a-2005, IEEE PC37.09b (Draft 3, September 2009), The IEEE Standards Dictionary: Glossary of Terms & Definitions, Definitions, IEEE Std C37.100-1992, and IEEE Std C37.100.1-2007, and are not repeated in this document. 7 Annex A and Annex B recall B recall these definitions as used in this standard and its tables.

5. Preferred ratings for Class S1 circuit breakers for cable systems The whole of Clause 5 with Table 1, 1, Table 2, 2, Table 3, 3, and Table 4 is 4 is dedicated to the Class S1 of circuit breakers formerly listed as indoor circuit breakers. Historically the predominant use of indoor circuit breakers was for use with cable cable systems. S1 S1 Class circuit breakers are for use with cable systems.

5.1 Information for Table 1, 1, Table 2, 2, and Table 3 (Numbers in parenthesis in the tables refer to the following correspondingly numbered items.) (1) The voltage ratings are based on ANSI C84.1-2006 [B2] [B2] where applicable and are the maximum voltages for which the circuit breakers are designed for and are the upper limit for operation. (2) The ratings in this column are the maximum time interval to be expected during a circuit-breaker opening operation between the instant of energizing the trip circuit and the interruption of the main circuit on the primary arcing contacts under certain specified conditions. The values may be exceeded under certain conditions as specified in IEEE Std C37.04b-2008, subclause covering rated interrupting time. (3) For 60 Hz, rated closing and latching current (kA, peak) of the circuit breaker is 2.6 times the rated short-circuit current. (If expressed in terms of kA, rms total current, the equivalent value is 1.55 times rated short-circuit current.) For 50 Hz, the kA peak is 2.5 times the rated short-circuit current and the rms total current is 1.47 times the rated short circuit current. (4) These values of TRV are changed from the previous publication of ANSI C37.06-2000. IEEE agreed to use the circuit-breaker S1 (cable connected circuit breakers) values from IEC 62271-100:2008 [B5], [B5], and the IEC agreed to use the circuit-breaker S2 (overhead connected circuit breakers) values from IEEE. The values are also changed by conversion of the former NEMA/ANSI exponential-cosine values to the two-parameter values. Several IEEE papers have been published on behalf of the Switchgear Committee explaining the harmonization efforts between IEC and IEEE. Refer to IEC 62271-100:2008 [B5] and [B5] and Dufournet and Montillet [B4]. [B4]. 3. (5) (5) Synthetic tests can be performed to prove the capability of values of t 3 in column 6 of Table 3. (6) The traditional North American continuous current rating of 1200 A has been retained in this standard, while IEC prefers the continuous current rating of 1250 A. It is possible that the continuous current rating might be changed to 1250 A in a future edition.

5.2 Information for Table 4 on 4 on preferred capacitance current switching ratings for Class S1 cable systems circuit breakers rated below 100 kV (Numbers in parentheses in table refer to the following correspondingly numbered items.) (1) For class C0 (general-purpose) circuit breakers, no ratings for back-to-back capacitor switching applications are established. The capacitor bank or cable shall be “isolated” as defined in IEEE Std C37.04a-2003, 5.11. For class C0 (general-purpose) circuit breakers exposed to transient inrush currents from nearby capacitor banks during fault conditions, the capacitance transient inrush peak current on closing shall not exceed the lesser of either (1.41 times rated short-circuit current), or 50 000 A peak. The product of transient inrush current peak and transient inrush current frequency shall not exceed 20 kAkHz. The service capability and circuit-breaker condition for this duty shall be as defined in IEEE Std C37.0122005, 4.2.1.1 (capacitor bank) or 4.2.2.1 (cable). (2) The circuit breaker shall be capable of switching any capacitive current of the ratings listed in the selected rating column by the user, in the preceding tables, at any voltage up to the rated maximum voltage. (3) The rated transient inrush current peak is the highest magnitude of current that the circuit breaker shall be required to close at any voltage up to the rated maximum voltage and shall be as determined by the system and unmodified by the circuit breaker. The rated transient inrush current frequency is the highest frequency that the circuit breaker shall be required to close at 100% rated back-to-back capacitor switching inrush current rating. (4) For application at less than 100% of rating, the product of the inrush current peak and frequency shall not exceed the product of the rated transient current peak and the rated transient inrush current frequency. (This product quantifies the maximum rate of change of inrush current and the minimum inductance between the banks or cables.) (5) For circuit breakers identified as a Class C1 or C2 (formerly referred to as definite purpose), purpose), the manufacturer shall state the inrush current peak and frequency at which the circuit breaker meets Class C1 or C2 performance. The stated inrush current peak and frequency may be the preferred values from Table 4 or 4 or other values as determined by the manufacturer. (6) (6) The transient inrush current in circuit breakers applied in GIS substations has a very high equivalent frequency (up to the MHz range, depending on the bus length) with an initial peak current of several thousand amperes (depending on the surge impedance of the bus). For reference, see IEEE Std C37.012-2005. Contact the manufacturer to determine the ability of the circuit breaker to withstand these inrush current stresses. (7) Tests to prove Class C2 have to be performed according to the requirements of Table 2 of IEEE Std C37.09a-2005. Tests to prove Class C1 have to be performed according to the requirements of Table 2A of IEEE Std C37.09a-2005. (8) The preferred ratings ratings and alternates 1or 1or 2 ratings have different values. These values are for qualification of circuit-breaker capacitance switching according to their capabilities. The preferred ratings lists the previous values indicated in ANSI C37.06-2000 and represent the standard values for circuit breakers. Alternate 1 ratings were added in particular for some ratings of vacuum and some other circuit breakers, and alternate 2 ratings represent the exceptional maximum values as seen by users and manufacturers in some world-wide applications. As of the time of the printing, only synthetic tests for alternate 2 are available in some laboratories. (9) For Class C1 and C2 circuit breakers exposed to transient inrush currents from nearby capacitor banks during fault conditions, the capacitance transient inrush peak current shall not exceed the close and latch (peak withstand) capability of the circuit breaker. This is considered an infrequent event, and therefore the circuit breaker should be expected to handle this duty twice in the life time of the circuit breaker without requiring maintenance maintenance of the contacts. contacts.




6. Preferred rating for Class S2 circuit breakers for line systems syst ems rated below 100 kV The whole of Clause 6 with Table 5, 5, Table 6, 6, Table 7, 7, and Table 8 is 8 is dedicated to the Class S2 of circuit breakers formerly listed as outdoor circuit breakers. Historically the predominant use of outdoor circuit breakers was for use with overhead line systems. S2 Class circuit breakers are for use with overhead line systems.

6.1 Information for Table 5 (Numbers in parenthesis in the table refer to the following correspondingly numbered items.) (1) The voltage ratings are based on ANSI C84.1-2006 [B2] [B2] where applicable and are the maximum voltages for which the circuit breakers are designed and are the upper limit for operation. (2) The rated interrupting time column is the maximum time interval to be expected during a circuit-breaker opening operation between the instant of energizing the trip circuit and the interruption of the main circuit on the primary arcing contacts under certain specified conditions. The value may be exceeded under certain conditions as specified in IEEE Std C37.04-1999, subclause covering rated interrupting time. (3) For 60 Hz, rated closing and latching current (kA, peak) of the circuit breaker is 2.6 times the rated short-circuit current. (If expressed in terms of kA, rms total current, the equivalent value is 1.55 times rated short-circuit current). For 50 Hz, peak is 2.5 times and rms total current is 1.47 times the rated short-circuit current. (4) The traditional North American continuous current rating of 1200 A and 3000 A have been retained in this standard, while IEC prefers the continuous current ratings of 1250 A and 3150 A (from the Renard R10 preferred numbers series). It is possible that the continuous current rating might be changed to 1250 A and 3150 A respectively in a future edition. (See ANSI/NEMA MG 1-2006 [B3]. [B3].

6.2 Information for Table 6 and 6 and Table 7 (Numbers in parenthesis in the tables refer to the following correspondingly numbered items.) (1) The voltage ratings are based on ANSI C84.1-2006 [B2] [B2] where applicable and are the maximum voltages for which the circuit breakers are designed and are the upper limit for operation. (2) Time t 3 for out-of-phase is 2 times time t 3 for terminal fault (as in IEC 62271-100:2008 [B5]). [B5]). See IEEE Std C37.04b-2008 5.9.1.2 for the calculation of t 3 .. (3) For out-of-phase fault, time t d 0.15 * t 3 . For terminal fault (T100) and short- line fault, time t d d is d is 0.05 * t 3. (4) The values of u c are calculated from Table 5. 5. The formula to calculate the value of u c is based on uc = k pp x k af af x

2 / 3 x U r r .

(5) Where two values of the times t d t’ are are given for terminal fault duty T100, separated by brackets, d and the second value in brackets can be used for testing if short-line fault tests are also made. If this is not the case, the times before the brackets apply. (6) Values of TRV Terminal Fault were not changed from the previous publication ANSI C37.06-2000 but were translated to the two-parameter method representation representation with improved accuracy. (7) Synthetic tests can be performed to prove the capability of values of t 3 in column 6 of Table 7. 7.

6.3 Information for Table 8 on 8 on preferred capacitance current switching ratings for Class S2 line systems circuit breakers rated below 100 kV (Numbers in parentheses in the table refer to the following correspondingly numbered items.) items.) (1) For general purpose circuit breakers (sometimes referred to as Class C0), C0), no established ratings for back-to-back capacitor switching applications. The capacitor bank or cable shall be “isolated” as defined in IEEE Std C37.04a-2003, 5.11. For general purpose circuit breakers (Class C0) exposed to transient inrush currents from nearby capacitor banks during fault conditions, the capacitance transient inrush peak current on closing shall not exceed the lesser of either 1.41 times rated short-circuit current or 50 000 A peak. The product of transient inrush current peak and transient inrush current frequency shall not exceed 20 kAkHz. The service capability and circuit-breaker condition for this duty shall be as defined in IEEE Std C37.0122005, 4.2.1.1 (capacitor bank) or 4.2.2.1 (cable). (2) The circuit breaker shall be capable of switching any capacitive current of the ratings listed in the selected rating column by the user, in the preceding tables, at any voltage up to the rated maximum voltage. (3) The rated transient inrush current peak is the highest magnitude of current that the circuit breaker shall be required to close at any voltage up to the rated maximum voltage and shall be as determined by the system and unmodified by the circuit breaker. The rated transient inrush current frequency is the highest frequency that the circuit breaker shall be required to close at 100% rated back-to-back capacitor switching inrush current rating. For application at less than 100% of rating, the product of the inrush current peak and frequency shall not exceed the product of the rated transient current peak and the rated transient inrush current frequency. (This product quantifies the maximum rate of change of inrush current and the minimum inductance between the banks or cables.) (4) For circuit breakers identified as a Class C1 or C2 (formally definite purpose) purpose) circuit breakers, the manufacturer shall state the inrush current peak and frequency at which the circuit breaker meets Class C1 or C2 performance. The stated inrush current peak and frequency may be the preferred values from Table 8 or other values as determined by the manufacturer. (5) The transient inrush current in circuit breakers applied in GIS substations has a very high equivalent frequency (up to the MHz range, depending on the bus length) with an initial peak current of several thousand amperes (depending on the surge impedance of the bus). For reference, see IEEE Std C37.012-2005. Contact the manufacturer to determine the ability of the circuit breaker to withstand these inrush current stresses. (6) Tests to prove Class C2 have to be performed according to the requirements of Table 2 of IEEE Std C37.09a-2005. Tests to prove Class C1 have to be performed according to the requirements of Table 2A of IEEE Std C37.09a-2005. (7) The preferred rating and alternatives 1 or 2 ratings have different values. These values are for qualification of circuit-breaker capacitance switching according to their capabilities. The preferred rating lists the previous values listed in ANSI C37.06-2000 and represents the usual standard values. Alternate 1 rating was added in particular for some ratings of vacuum and some other circuit breakers. Alternate 2 rating represents the exceptional maximum values seen by users and manufacturers in world-wide applications. As of the time of the printing, only synthetic tests for alternate 2 are available in some laboratories. (8) For Class C1 and C2 circuit breakers exposed to transient inrush currents from nearby capacitor banks during fault conditions, the capacitance transient inrush peak current shall not exceed the close and latch (peak withstand) capability of the circuit breaker. This is considered an infrequent event, and therefore the circuit breaker should be expected to handle this duty twice in the life time of the circuit breaker without requiring requiring maintenance maintenance of the contacts. contacts.




7. Preferred ratings for circuit breakers rated 100 kV and above This whole Clause 7 with Table 9 to Table 14 14 is dedicated to circuit breakers rated 100 kV and above, including circuit breakers applied to gas-insulated substations.

Numbers in parenthesis refer to the items in 7.1. 7.1.




7.1 Information for Table 9 (Numbers in parenthesis in the table refer to the information correspondingly numbered items.) (1) The voltage ratings are based on ANSI C84.1-2006 [B2] [B2] where applicable and are the maximum voltages for which the circuit breakers are designed and are the upper limit for operation. (2) The rated interrupting time column is the maximum time interval to be expected during a circuit-breaker opening operation between the instant of energizing the trip circuit and the interruption of the main circuit on the primary arcing contacts under certain specified conditions. The value may be exceeded under certain conditions as specified in IEEE Std C37.04-1999, subclause covering rated interrupting time. (3) For 60 Hz, the rated closing and latching current (kA, peak) of the circuit breaker is 2.6 times the rated short-circuit current. (If expressed in terms of kA, rms total current, the equivalent value is 1.55 times rated short-circuit current.). For 50 Hz, the rated closing and latching current (kA, peak) of the circuit breaker is 2.5 times the rated short-circuit current. (If expressed in terms of kA, rms total current, the equivalent value is 1.47 times the rated short-circuit current.). (4) The traditional North American continuous current ratings of 1200 A and 3000 A have been retained in this standard, while IEC prefers the continuous current ratings of 1250 A and 3150 A (from the Renard R10 preferred numbers series). It is possible that the continuous current rating might be changed to 1250 A and 3150 A respectively in a future edition (see ANSI/NEMA MG 1-2006 [B3]). [B3]).

7.2 Information for Table 10, 10, Table 11, 11, and Table 12 (Numbers in parenthesis in the tables refer to the following correspondingly numbered items.) (1) The voltage ratings are based on ANSI C84.1-2006 [B2] [B2] where applicable and are the maximum voltages for which the circuit breakers are designed and are the upper limit for operation. (2) Time t 2 for out-of-phase is 2 times time t 2 for terminal fault (as in IEC 62271-100:2008 [B5]). [B5]). See IEEE Std C37.04b-2008 5.9 for the calculation of t 2 (3) For out-of-phase, time t d d is the same as for terminal fault and short-line fault. (4) The values of uc are calculated from Table 9. 9. The value is calculated such as: uc = k af af x k pp x

2 / 3 x U r

(5) Where two values of the times t d t’ are are given, the second value in brackets can be used for testing d and if short-line fault tests are required. If this is not the case, the first value before the brackets applies. (6) Table 11 11 only: for rated voltages of 170 kV and higher systems are considered to be effectively grounded, therefore the recovery voltage for out-of-phase is 2.0 times the rated maximum voltage Ur divided by √3. (7) Table 12 only: 12 only: In the process of harmonization with IEC 62271-100:2008 [B5], [B5], values of T30 and T10 with a first pole to clear factor k pp = 1.3 were changed. At T30, the amplitude factor k af af is changed to 1.54 instead of 1.58 and for T10 the amplitude factor k af af is increased to 1.76 (it corresponds to an amplitude factor of 0.9 x 1.7 with k pp = 1.5). The numbers on these lines are thus harmonized. (8) Values of TRV terminal fault were not changed from the previous publication ANSI C37.06-2000 but were translated to the two- or four-parameter representation with improved accuracy. (9) Since the out-of-phase switching duty is required for only certain circuit-breaker applications, it is not considered necessary to include this as a standard rating for general purpose circuit breakers. This has not changed from previous editions. (10) The assigned out-of-phase switching current rating is the maximum out-of-phase current that the circuit breaker shall be capable of switching at a rated power frequency, out-of-phase recovery voltage equal to 2 times the rated maximum voltage for grounded systems, and 2.5 times the rated maximum voltage for ungrounded systems (see IEEE Std C37.09-1999). If a circuit breaker has an assigned outof-phase switching current rating, the preferred rating shall be 25% of the rated (symmetrical) shortcircuit current expressed in kA, unless otherwise specified.

7.4 Information for Table 14 on 14 on preferred capacitance current switching ratings for circuit breakers rated 100 kV and above, including circuit breakers applied in gasinsulated substations

(Numbers in parentheses in the table refer to the following correspondingly numbered items.) (1) For general-purpose circuit breakers (Class C0) no ratings for back-to-back capacitor switching applications are established. The capacitor bank or cable shall be “isolated” as defined in IEEE Std C37.04a-2003, 5.11. For general-purpose circuit breakers (Class C0) exposed to transient inrush currents from nearby capacitor banks during fault conditions, the capacitance transient inrush peak current on closing shall not exceed the lesser of either 1.41 times rated short-circuit current or 50 000 A peak. The product of transient inrush current peak and transient inrush current frequency shall not exceed 20 kAkHz. The service capability and circuit-breaker condition for this duty shall be as defined in IEEE Std C37.0122005, 4.2.1.1 (capacitor bank) or 4.2.2.1 (cable). (2) The circuit breaker shall be capable of switching any capacitive current of the ratings listed in the selected rating column by the user, in the preceding tables, at any voltage up to the rated maximum voltage. (3) The rated transient inrush current peak is the highest magnitude of current that the circuit breaker shall be required to close at any voltage up to the rated maximum voltage and shall be as determined by the system and unmodified by the circuit breaker. The rated transient inrush current frequency is the highest frequency that the circuit breaker shall be required to close at 100% rated back-to-back capacitor switching inrush current rating. For application at less than 100% of rating, the product of the inrush current peak and frequency shall not exceed the product of the rated transient current peak and the rated transient inrush current frequency (inherent value). (This product quantifies the maximum rate of change of inrush current and the minimum inductance between the banks or cables.) (4) For circuit breakers identified as a Class C1 or C2 (formally referred to as definite purpose), purpose), the manufacturer shall state the inrush current peak and frequency at which the circuit breaker meets Class C1 or C2 performance. The stated inrush current peak and frequency may be the preferred values from Table 14 or 14 or other values as determined by the manufacturer and the user. (5) (5) The transient inrush current in circuit breakers applied in GIS substations has a very high equivalent frequency (up to the MHz range, depending on the bus length) with an initial peak current of several thousand amperes (depending on the surge impedance of the bus). For reference, see IEEE Std C37.012-2005. Contact the manufacturer to determine the ability of the circuit breaker to withstand these inrush current stresses. (6) Tests to prove Class C2 are to be performed according to the requirements of Table 2 of IEEE Std C37.09a-2005. C37.09a-2005. Tests to prove Class C1 are to be performed according to the requirements of Table2A of IEEE Std C37.09a-2005. (7) The preferred rating is those from the previous ANSI C37.06. Alternates 1, 2, or 3 ratings have different values for qualification of circuit-breaker capacitance switching capabilities.




The preferred rating lists the previous values listed in ANSI C37.06-2000 and represent the usual values that have historically been used for circuit breakers previously referred to as definite purpose circuit breakers. Alternate 1 rating was added in particular for some ratings of vacuum and some other circuit breakers. The values of inrush current magnitude and inrush frequency are generally lower than the preferred rating (historical values). Alternates 2 and 3 ratings represent alternatives of exceptional maximum capacitance switching values as seen in a survey of users and manufacturers in world-wide applications. applications. Alternate 2 rating was developed by taking the 90th percentile of the inrush current frequency seen in the survey and matching it with the corresponding inrush current magnitude at that 90th percentile inrush frequency. Similarly, alternate 3 rating was developed by taking the 90th percentile of the inrush current magnitude seen in the survey and matching it with the corresponding inrush current frequency at that 90th percentile inrush current magnitude. These values of inrush current magnitude and inrush frequency are generally higher than preferred rating (historical values). All values have been rounded. It is necessary to choose which alternative shall apply to the circuit breaker. Refer to application guides IEEE Std C37.010-1999, IEEE Std C37.011-2005, IEEE Std C37.012-2005, and IEEE Std C37.0151993 for guidance on this selection. (8) For Class C1 and C2 circuit breakers exposed to transient inrush currents from nearby capacitor banks during fault conditions, the capacitance transient inrush peak current shall not exceed the close and latch (peak withstand) capability of the circuit breaker. This is considered an infrequent event, and therefore the circuit breaker should be expected to handle this duty twice in its life time without requiring maintenance of the contacts. (9) This current rating column is applicable to all ratings of preferred continuous currents.

8. Preferred dielectrics withstand ratings for circuit breakers The whole of Clause 8 with Table 15 and 15 and Table 16 is 16 is dedicated to all types of circuit breakers, including circuit breakers applied to gas-insulated substations. Preferred ratings are given for the dielectric withstand and external creepage insulation to ground.

9.1 Information for Table 17 (Numbers in parentheses in the table refer to the following correspondingly numbered items.) items.) (1) Table 17may 17may be used as a guide for applying circuit breakers to switching conditions conditions that differ from those specified. In such cases, the number of operations may differ from those tabulated, but the cumulative duty on the circuit breaker must be within the service capability as defined in IEEE Std C37.04-1999, 5.8.2.5. (2) Servicing consists of cleaning, tightening, adjusting, lubricating, etc., as recommended by the manufacturer, and assumes usual service conditions. Maintenance intervals are usually based on both an elapsed time and a number of operations, whichever occurs sooner as p er the manufacturer requirements. (3) With rated control voltage applied. See Table 18. 18. frequency of operation see IEEE Std C37.04-1999, 5.10. (4) For frequency (5) No funct functional ional parts parts shall shall have been replaced replaced prior to compl completio etion n of the specified specified number number of of operati operations. ons. (6) After completion of the specified number of operations, the circuit breaker shall withstand rated maximum voltage in the open position, and the resistance of the current carrying circuit from terminal to terminal, measured with a current of at least 100 A flowing, shall not be greater than 200% of the maximum value given by the manufacturer for the circuit breaker when new. Under these conditions, the circuit breaker is considered capable of carrying rated continuous current, at rated frequency, without injurious heating until maintained, and of performing one interruption at rated short-circuit current or at a related capability. After completion of this series of operations, functional part replacement and general maintenance may be necessary. (7) If a short-circuit operation occurs before the completion of the listed operations, maintenance is recommended and possible functional part replacement may be necessary, depending on previous accumulated duty, fault magnitude, and expected future operations. (8) Requirements are based on specified maintenance intervals in accordance with Column 4. (9) When closing and opening current equal to rated continuous current at rated maximum voltage with power factor between 80% leading and 80% lagging. (10) When closing current equal to 600% of rated continuous current at rated maximum voltage with power factor of 30% or less and when opening current equal to rated continuous current at rated maximum voltage with power factor between 80% leading and 80% lagging. (11) Classes S1 and S2 are for circuit breakers below 100 kV. Above 100 kV, all circuit breakers have the same characteristics, even if installed in indoor or outdoor substations such as GIS. Ratings of circuit breakers under Class S2 and circuit breakers rated 100 kV and above also apply for circuit breakers in gas-insulated substation installations.




10. Control voltage ranges for circuit breakers Operating mechanisms are designed for the rated control voltages listed with operational capability throughout the indicated voltage ranges to accommodate variations in source regulation, coupled with dc battery low charge levels, as well as dc battery high charge levels maintained with floating charges. The maximum voltage is measured at the point of user connection to the circuit breaker [see items (12) and (13) in 10.1] 10.1] with no operating current flowing, and the minimum voltage is measured with maximum operating current flowing. a

10.1 Information for Table 18 Numbers in parentheses parentheses in Table 18 refer 18 refer to the following correspondingly numbered items. items. (1) Electrically operated motors, contactors, solenoids, valves, and the like, need not carry a nameplate voltage rating that corresponds to the control voltage rating shown in the table as long as these components perform the intended duty cycle (usually intermittent) in the voltage range specified. (2) Relays, motors, or other auxiliary equipment that functions as a part of the control for a device shall be subject to the voltage limits imposed by this standard, whether mounted at the device or at a remote location.




(3) Circuit-breaker devices, in some applications, may be exposed to control voltages exceeding those specified here due to abnormal conditions such as abrupt changes in line loading. Such applications require specific study, and the manufacturer should be consulted. Also, application of switchgear devices containing solid-state control, exposed continuously to control voltages approaching the upper limits of ranges specified herein, require specific attention, and the manufacturer should be consulted before application is is made. (4) Includes supply for pump or compressor motors. Note that rated voltages for motors and their operating ranges are covered in ANSI/NEMA MG 1-2006 [B3]. [B3]. (5) (5) It is recommended recommended that the coils of closing, auxiliary, and tripping devices that are connected continually to one dc potential should be connected to the negative control bus to minimize electrolytic electrolytic deterioration. (6) 24 V or 48 V tripping, closing, and auxiliary functions are recommended only when the device is located near the battery or where special effort is made to ensure the adequacy of conductors between battery and control terminals. 24 V closing is is not recommended. (7) Includes heater circuits. (8) Voltage ranges apply to all closing and auxiliary devices when cold. Breakers utilizing standard auxiliary relays for control functions may not comply at lower extremes of voltage ranges when relay coils are hot, as after repeated or continuous operation. (9) DC control voltage sources, such as those derived from rectified alternating current, may contain sufficient inherent ripple to modify the operation of control devices to the extent that they may not function over the entire specified voltage ranges. (10) This table also applies for circuit breakers in gas-insulated substation installations. (11) In cases where other operational ratings are a function of the specific control voltage applied, tests in IEEE Std C37.09-1999 and IEEE Std C37.09a-2005 may refer to the “rated control voltage.” In these cases, tests shall be performed at the levels in column 1. (12) For an outdoor circuit breaker, the point of user connection to the circuit breaker is the secondary terminal block point at which the wires from the circuit-breaker operating mechanism components are connected to the user’s control circuit wiring. (13) For an indoor circuit breaker, the point of user connection to the circuit breaker is either the secondary disconnecting contact (where the control power is connected from the stationary housing to the removable circuit breaker) or the terminal block point in the housing nearest to the secondary disconnecting contact. (14) The voltage ratings of protective relays and other devices used to initiate operation of the circuit breaker controls may have voltage requirements requirements other than of the circuit breaker. All other capabilities of these devices shall be as required by IEEE Std C37.90-2005.

11.1 Information for Table 19 Numbers in parentheses parentheses in Table 19 refer 19 refer to the following correspondingly numbered items. items. (1) Circuit breakers rated for reclosing shall be capable of reclosing within these times on an instantaneous reclosing cycle, O + 0.3 s + CO, when operating in conjunction with an automatic reclosing device. These time-values are based on maintaining rated control voltage or operating pressure at the operating mechanism. In case the control voltage or pressure drops to 90% of rated voltage or pressure, the reclosing times will be increased to 110% of the above values. Consult the manufacturer for special reclosing requirements. NOTE 1— Reclose time time as defined in IEEE Std C37.100-1992 is “The interval between the time when the actuating quantity of the release (trip) circuit reaches the operating value (b reaker being in the closed position) and the reestablishment of the circuit on the primary arcing contacts on the reclosing stroke,” i.e., the time from trip initiation to contact touch in all three poles. Some circuit breakers require a minimum time requirement between the opening and next closing of the circuit breaker to allow proper mechanical functioning of the mechanism. This minimum time requirement may be implemented internally by circuit-breaker control circuitry or externally by means of of protection and control circuitry; and in either case must be implemented implemented to prevent damage to the circuit breaker. 11 NOTE 2—A time in addition to the minimum mechanical reclose time, and known as “ t min min” may be imposed by the circuit-breaker characteristics; however it is not a time that can be tested on-site. Time “ t min min” is commonly known as the dead time, i.e., time, i.e., the interval of time between final arc extinction in all poles and first reestablishment of current in any pole in the subsequent closing operation. The mechanical reclose time is important from the perspective of installation and maintenance. maintenance. The time “t “t min min” is important from the perspective of system protection and control.

(2) Reclosing ratings for indoor circuit-breaker continuous current ratings greater than 1200 A have not been established.

Annex A

(normative) TRV symbols used in the tables with the two-parameter method The preferred ratings are for 50 Hz and 60 Hz systems. The two-parameter method is one of the methods used in these tables to represent the transient recovery voltage (TRV). The basic inherent shape of the rated transient recovery voltage envelope is the “one-minus-cosine” “one-minus-cosine” (1–cosine) shape. See TRV envelope curves in IEEE Std C37.04-1999 for the 1–cosine shape. For the development of the two-parameter method based on the 1–cosine shape, refer to Clause 5 of IEEE Std C37.04b-2008. The rated interrupting times and peak recovery voltage values and times given are all based on 60 Hz systems.

A.1 General explanation of symbols The symbols used in this standard are as follows and are essentially those in the IEC 62271-series standards and are also used in IEEE Std C37.04b-2008: U r r = rated maximum voltage. Sometimes U r r is represented by V in in other standards. It is measured in kV rms. k pp = first pole to clear factor. It may be represented in other documents as Kf. When systems below 100 kV are operated on non-effectively grounded systems, a first pole-to-clear factor of 1.5 is required. k af af = transient amplitude factor. It may be represented in other documents as Ka. In systems below 100 kV the amplitude factor can be of 1.4 or 1.54 as determined by another standard (see IEEE Std C37.04-1999, 5.9.1.1) or 1.25 for out-of-phase interrupting capability (see IEEE Std C37.04b-2008, 5.9.2.3.1). uc = Reference voltage, a peak (crest) value in kV. It is a measure of the TRV. It was referenced as E 2 in former documents. It is related to the rated maximum voltage in kV by the formula: uc = k pp x k af af x

2 / 3 x U r r

(i.e., for example 1.5 x 1.54 x

2 / 3 x U r r = 1.886 x U for overhead line connected circuits below 100 kV) r r

t 3 = time to reach uc in microseconds, and it is calculated from the old value of T2 by t 3 = [T2 * Kt3] / 1.138 Kt 1 , Kt 2 , or Kt 3 = Multipliers are defined in Table 1 in the applications guide IEEE Std C37.011-2005 4.2.1 and vary according to the voltage and the interrupting current as a percentage of rated short circuit current. Their values are listed in Figure 9 for its values and applications in the same applications guide, IEEE Std C37.011-2005. t d = is the delay time in microseconds. t d d for test duty T100 is 0.15 x t 3 for Class S1 cable connected systems, and 0.05 x t 3 for Class S2 line connected systems at below 100 kV . t d 0.15 x t 3 for all test duties d is T60, T30, and T10, and for out-of-phase interrupting in all cases. u’ = reference voltage in kilovolts t’ = time to reach u’ in microseconds = t d + (u’ / RRRV)




Figure A.1 and Figure A.2 illustrate the concept of RRRV used in these tables represented by the ratio: uc / t 3 Comments If the source of power to a circuit breaker is a single transformer or a bank of transformers and there are no substantial capacitances or loaded feeders connected to the source side of the circuit breaker, the transient recovery voltage may be more severe than those covered in Table 1 to Table 16. 16. For such applications, refer to ANSI C37.06.1 [B1] [B1] for preferred ratings of definite purpose circuit breakers for fast TRV rise time.

The new symbols used are: uc , u’, t d d , t’, t 3, compared to the old symbols such as E2 and T2. The rated transient recovery voltage envelope is the “one-minus-cosine” (1–cosine) shape. The symbols are in clause 1 and are calculated values in accordance with this figure are shown in all tables.




Annex B

(normative) Symbols used in the tables with the four-parameter method The preferred ratings are for 50 Hz and 60 Hz systems. Applications at other system frequencies should receive special consideration, see IEEE Std C37.010-1999. The rated interrupting times and peak recovery voltage values and times given are all based on 60 Hz systems. Values have generally been rounded off. The number of significant digits after the decimal point varies according to the meaning of the value. The four-parameter method is used in these tables to represent the transient recovery voltage for circuit breakers rated 100 kV and above and for T100, T60 faults. The four-parameter method is applied for terminal faults (T100, T60), short-line faults, and out-of-phase faults. The two-parameter two-parameter method is used to represent the transient recovery voltages at T30 and T10. The rated transient recovery voltage envelope has been historically the “higher of an exponential waveform and a 1–cosine waveform” shape. See TRV envelope curves in IEEE Std C37.04-1999 5.9.1.2 and see also TRV envelope curves in IEEE Std C37.04b2008 Clause 5.

B.1 General explanation of symbols The symbols used are as follows and are essentially those used in the IEC 62271-series standards. U r r = rated maximum voltage. Sometimes U r r is represented by V in in other standards. standards. k pp = first pole to clear factor. It may be represented in other documents as K f . Systems below 100 kV may be operated on non-effectively grounded systems and a first pole-to-clear factor of 1.5 is required for terminal faults. For 100 kV and above, systems are usually grounded, and the factor is 1.3 for terminal faults in this case. In certain applications where the systems may be grounded and where the likelihood of non-effectively grounded faults cannot be ignored, the factor of 1.5 for terminal faults is used. k af af = transient amplitude factor. It may be represented in other documents as K a. In systems 100 kV and above the amplitude factor can be of 1.40, at T100 as specified in IEEE Std C37.04b-2008 and 1.25 for outof-phase interrupting capability. u1 = first reference voltage in kV, a peak (crest). It is calculated as: u1 = 0.75 x k pp x

2 / 3 x U r r

t 1 = time to reach u1 in microseconds. It is derived from u1 and the specified value of the RRRV, u1 / t 1 . uc = second reference voltage a peak (crest) value in kV. It is a measure of the TRV. It was referenced as E 2 in former documents. It is related to the rated maximum voltage in kV by the formula: uc = k af 2 / 3 x U r , where k af af x k pp x af is equal to 1.4 for terminal fault T100 and short-line faults and 1.25 for out-of-phase faults.




t 2 = time to reach uc in microseconds (used only in the four parameters method) is equal to 4 t 1 for test duty T100 and for the supply side circuit for short-line fault, between 2 t 1 and 4 t 1 for out-of-phase interrupting. Time t 2 is equal to 3 t 1 for T60. t 3 = time to reach uc in microseconds (used only in the two parameters method) and it is calculated from the old value of T 2 by t 3 = [T 2 * Kt 3] / 1.138. Kt 1 , Kt 2 , or Kt 3 = Multipliers are defined in Table 1 of the applications guide IEEE Std C37.011-2005 4.2.1

and vary according to the voltage and the interrupting current as a percentage of rated short circuit current. Their values are listed in Figure 9 for its values and applications in the same applications guide IEEE Std C37.011-2005. t d = is the delay line in microseconds and is between 2 μs and 0.28 t 1 for test duty T100, between 2 μs and 0.3 t 1 for test duty T60, between 2 μs and 0.1t 1 for the out-of-phase test duty u’ = reference voltage in kV and is equal to u1 / 2 for test duties T100 and T60 and for the supply side

circuit for the short-line fault. t’ = time to reach u’ in microseconds

Figure B.1 and Figure B.2 illustrate the concept of RRRV used in subsequent tables represented by the ratio: u1/t 1.
