This Setting group is critical for all over-current protection features that have settings specified in multiples of CT rating. When the relay is ordered, the phase, ground, and sensitive ground CT inputs must be specified as 1 Amp. As the phase CTs are connected in wye (star), the calculated phasor sum of the three phase currents (Ia + Ib + Ic = Neutral Current = 3 I0) is used as the input for protection of the neutral over-current. In addition, a zero-sequence (core balance) CT which senses current in all of the circuit primary conductors, or a CT in a neutral grounding conductor may also be used. For this configuration, the ground CT primary rating must be entered. To detect low level ground fault currents, the sensitive earth input may be used. In this case, the sensitive ground CT primary rating must be entered. For additional details on CT connections, refer to (see 13.11. Current Inputs Wiring Diagram).

6.4.7. Fault Locator The fault locator calculates the distance to the fault. When fault occurs the magnitude and the phase of voltage and current are varied, and then fault type(phase to ground, (phase to phase to ground), phase to phase, three phase) can be determined by the analysis of these variations, and fault distance can be calculated by the estimation of the apparent impedance. This calculation is based on the assumptions that the feeder positive and zero sequence impedance are a constant per unit distance and fault impedance is composed of pure resistance. In calculating, errors could be introduced by several reasons(fault resistance etc.), the major error due to fault resistance can be reduced by comparing the prefault current and voltage to the fault current and voltage. For more accurate calculation, the prefault data is required at least 2 cycles, and the after fault data is required at least 2 cycles. If the line impedance per unit and total length were known, the fault distance can be easily achieved, but source impedance is not required. Fault data may not be accurate for a close-into-fault condition where there is no prefault power flow. In case of closing, during a reclose sequence, the apparent distance of the first fault is very useful. The algorithm for the fault locator is most applicable to a radial three-phase feeder. Faulted distribution system is considered as following simplified “Figure 6-3. Faulted distribution system circuit” for example.

6.5. Loop Control The purpose of using LOOP CONTROL is to isolate a fault area and protect the normal operation area by coordinating with C/B or Recloser when a fault occurs. Loop control is able to provide automation system with using Sectionalizing Recloser, MID point Recloser, TIE point Recloser. Loop control is performed by voltage sensing of DV(Dead Line Voltage), LV(Live Line Voltage). Sectionalizing Recloser(SEC) When a fault is occurred from the source side of Sectionalizing Recloser and backup C/B operates, the line becomes DV and if it continues, it is figured as a permanent fault. Hence, Sectionalizing Recloser is opened. After Sectionalizing Recloser is opened and TIEpoint Recloser is closed, the current flows in opposite way. Therefore, the load side of Sectionalizing Recloser can keep the live line. When Load side of Sectionalizing Recloser has a fault, OCR Function is operated and the load side is disconnected. MIDpoint Recloser(MID) When a fault is occurred in the source side of MIDpoint Recloser and backup C/B or Sectionalizing Recloser operates, the line becomes DV status and if it continues, it is figured as a permanent fault, then automatically the setting is changed to Alternate setting. After changed to Alternate setting, when TIEpoint Recloser is closed, the current flows in opposite way. During TIEpoint Recloser closed, when a fault occurs, MIDpoint Recloser trips once and lockouts. After recovering the fault, connect C/B and when the line becomes LV, the setting is automatically changed to Primary setting and MIDpoint Recloser is closed. When Load side of MIDpoint Recloser gets a fault, OCR Function is operated and disconnects the load side. TIEpoint Recloser (TIE) TIEpoint Recloser automatically closes when either Source side or Load side becomes DV. When a fault occurs during automatic closing, the recloser trips once and lockouts. TIEpoint recloser automatically opens when loop control operates automatic closing at both side and when both side becomes DV.

7.1.1. Reclose (79) After a fault has occurred, the Reclose element closes the recloser when the programmed reclose interval time expires. The number of operation lockout setting is programmed one to five, and each reclose shot has its own separate reclose interval timer. If the fault is permanent and the recloser continues to trip and reclose, the Reclose element will continue to increment the operating counter. If this continues to the maximum number of the operating lockout programmed in the Reclose element, the reclose logic lockouts. At this moment, if make close operation remotely or locally, Lockout is released and fault detecting is activated. Also, if the fault is temporary, the Lockout sequence of the Recloser is Rest by Reset logic. If the fault is transient, then the reclose logic is reset by the reset logic. The reclosing element can be disabled in the Primary, Alternate settings by one operating lockout or by [RECLOSE ENABLED] push button on user interface panel. The Reclose Element should be enabled to the following settings.

7.1.2. Phase (Fast/Delay) Time Overcurrents (51P) The ETR300-R has two phase time overcurrent elements. The phase time overcurrent element contained in the ETR300-R, is set based on CT secondary current as connected to the current inputs. The phase time overcurrent element is the most commonly used as a protective element for distribution systems and also used in both down-line and back-up recloser protection. The phase time overcurrent element provides a time delay versus current for tripping that is used for an inverse time curve characteristic coordinated with current pickup value, curve type, time dial, time adder, minimum response time setting and reset type. This inverse characteristic means that time overcurrent element operates slowly on small values of current above the pickup value and operates faster when current increases significantly above the pickup value. The phase time overcurrent element is enabled in the Primary, Alternate settings and PROTECTION ENABLED in user interface panel. Multiple time curves and time dials are available for the phase time overcurrent element to respectively coordinate with other protection elements in the ETR300-R and other external devices on the distribution system. ANSI, IEC, ESB, USER and non-standard time current curves are included in the ETR300-R. A User Programmable curve option is also available for user to allow creating custom’s time current curves for more enhanced coordination than the standard curve types. The Reset type can be either instantaneous or linear. The phase time delay reset mode applies to the ANSI, IEC, ESB, USER curves. The instantaneous mode is used to coordinate with other instantaneous reset devices such as a recloser or other protective equipment on the distribution system. In the instantaneous mode, the time overcurrent element will reset instantaneously when the measured current level drops below the pickup setting for one cycle. Linear reset mode, the recloser is used for the cooperation with the protection device necessary for delay time as mechanical relay reset. If the recloser is closed by pressing the CLOSE button on the front panel, or by an remote control or via SCADA, the phase time overcurrent element is prevented from tripping for a period specified by the Cold load pickup scheme.

7.1.3. Ground (Fast/Delay) Time Overcurrent (51G) The ETR300-R has two ground time overcurrent elements. The ground time overcurrent element in the ETR300-R is set based on CT secondary current as connected to the current inputs. The ground time overcurrent element is the most commonly used as a protective element for distribution systems and also used in both down-line and back-up recloser protection. The ground time overcurrent element provides a time delay versus current for tripping that is used for an inverse time curve characteristic coordinated with current pickup value, curve type, time dial, time adder, minimum response time setting and reset type. This inverse characteristic means that time overcurrent element operates slowly on small values of current above the pickup value and operates faster when current increases significantly above the pickup value. The ground time overcurrent element is enabled in the Primary, Alternate settings and PROTECTION ENABLED in user interface panel. Multiple time curves and time dials are available for the ground time overcurrent element to closely coordinate with other protection elements within the ETR300-R and other external devices on the distribution system. ANSI, IEC, ESB, USER and non-standard time current curves are included in the ETR300-R. A User Programmable curve option is also available allowing the user to create customer time current curves for more enhanced coordination than the standard curve types. The Reset type can be either instantaneous or linear. The ground time delay reset mode applies to the ANSI, IEC, ESB, USER curves. The instantaneous mode is used to coordinate with other instantaneous reset devices such as a recloser or other protective equipment on the distribution system. In the instantaneous mode the time overcurrent element will reset instantaneously when the current level measured by the ETR300-R drops below the pickup setting for one cycle. Linear reset mode, the recloser is used for the cooperation with the protection device necessary for delay time as mechanical relay reset. If the recloser is closed by pressing the CLOSE button on the front panel, or by an remote control or via SCADA, the ground time overcurrent element is prevented from tripping for a period specified by the Cold load pickup scheme.

7.1.12. Cold Load Pickup The cold load pickup function is used to prevent the recloser from incorrectly operating caused by the restoration of load supply or the cold load current of load side. ETR300-R provides “CLPUType 1” to prevent the recloser from operating wrong by instantaneous inrush current occurring by the closing of device on a power line and “CLPU-Type 2” to prevent protection elements from operating wrong by the cold load current caused by applying voltage to a transformer, a reactor or a long-distance line.

7.1.12.1. Cold Load Pickup – Type 1 The settings of “CLPU-Type 1” are separated and set respectively for phase, ground, SEF or negative phase over current element. In the state of the function to restrain the inrush current activated, the overcurrent protection element will be operated under settings of “CLPU-Type 1” function at the restoration of load supply. NOTE: According to setting of “Make use ‘I’”, the condition to decide the restoration of load supply will be changed. If “YES” is set, the decision is made when the load current becomes over 2A. If “NO” is set, the decision is made when a recloser is closed (51A) by local or remote control. When a distributed system is closed after long-time outage, the inrush current over overcurrent pickup level may occur. At occurrence of the cold load pickup, ETR300-R increases the pickup level of overcurrent element during a certain period of time, the Fast overcurrent protection element is not operated and the Delay overcurrent protection element is always operated regardless of the cold load pickup function. (The High Current Trip and High Current Lockout are always operated regardless of the cold load pickup function) If a fault occurs on distributed system, an overcurrent protection element is operated by the cold load pickup function and a recloser becomes lockout after oneshot trip regardless of total number of shots. A power is lost and then after certain outage time, the algorithm of cold load pickup function is applied at the restoration of load supply. If the “Make use ‘1’” is set to be “YES”, the algorithm is applied when a load current becomes 0 and then it is restored after certain outage time. If “NO” is set, the algorithm is applied when a recloser is opened and then after certain outage time, the

recloser is closed manually. If the fault current over the cold load pickup level occurs, the protection element by the cold load pickup function is operated immediately. If the power loss (opening or load current loss) is sustained for a long time more than certain outage time, the pickup current of time overcurrent element is changed to be the setting value of the cold load pickup current. After the restoration of load supply (manually closing or restoration of load current), protection functions are normally operated when the Restore minimum time (RMT) is expired.

Figure 7-5. The Cold Load Pickup Characteristic The cold load pickup function is operated according to the following rules. The setting to use the cold load pickup function is set to be ON (set to TRIP or TR&AR), the cold load pickup level is preset and then the cold load pickup function is activated at manual close or restoration of load current. If the level of over current occurring at the restoration of load supply is over the cold load pickup current, the Lockout is done by protection function after oneshot trip (Refer the Inrush Current 1 in “Figure 7-6. The Restore Minimum Time Characteristic”). If the over current is below cold load pickup current and overcurrent pickup current, protection functions are not operated during a period of Restore minimum Time (RMT), (Refer the Inrush

Current 2 in “Figure 7-6. The Restore Minimum Time Characteristic”). After RMT, the protection functions are operated. However, if the over current is dropped below overcurrent pickup current during the RMT, the cold load pickup function is reset after reset time (Refer the Inrush Current 3 in “Figure 7-6. The Restore Minimum Time Characteristic”).

7.1.12.2. Cold Load Pickup – Type 2 In the state of cold load, this type is used to restrain the operation of protection functions to over current occurring by change of load (the close of a switch on long-distance line, incoming heavy load etc.). This function to restrain protection functions rises or drops the pickup level of time overcurrent element during certain time (E-CLP time) defined by a user. Over Current Pickup Level Step Up At power loss (a recloser is opened or a load current is 0A), the current of Over Current Pickup is risen as follows.

⎛ Without Supply Time ⎞ Operational Cold Load Multi' = 1 + ⎜⎜ × ( E − CLP Multi' −1) ⎟⎟ ⎝ E − CLP Time ⎠ As example, when E-CLP Multi and E-CLT Time are set to be 3.0 and 60min respectively, over 30 min after power loss, the applied cold load multiple is 2. If the minimum working currentis set to be 200A, the current of Over Current Pickup becomes 400A, twice as much as the minimum working current. In addition, after 60 min, the cold load multiple is fixed to be 3. Over Current Pickup Level Step Down If power is restored (manual closed or restoration of load current (over 2A)), the current of Over Current Pickup is dropped with the same speed when rising until the cold load multiple becomes 1. When E-CLP Multi and E-CLP Time are set to be 3.0 and 60 min respectively, the graph of the cold load multiple in “Figure 7-7. Cold Load Multipilier” is shown as follows. NOTE: The risen level of overcurrent pickup by multiple of cold load is the pickup level to operate overcurrent protection element. The standard current level of TC curve is a minimum working current.

7.1.13. Directional Controls (67) The directional Controls provide time protection in the direction of power flow. The directional Controls are necessary for the protection of multiple feeders, when it has the necessity of finding faults in different directions. The directional controls are composed of phase, gound, sensitive ground, and negative sequence overcurrent elements. If directional controls are selected, it will determine whether current flow in each phase is in forward or reverse direction, as determined by the connection of the phase CTs, selected Maximum Torque Angle (MTA), voltage and current phasors. To increase security of all directional controls, add one power frequency cycle of intentional delay to prevent incorrect operation. The directional controls have each three settings. The directional controls settings can be different in the Primary and Alternate settings.

7.1.13.1. Phase Directional Controls (67P) Normal voltage V1 provides phase pole direction in Power line system. Phase direction is determined by comparing normal voltage(V1) and normal current(I1). If an angle between normal voltage(V1) and normal current(I1) is within ± 90˚, the direction is forward otherwise it is backward(reverse direction). Maximum torque angle is set between ∠0˚ and ∠359˚. Max torque initial angle is set for lags Normal voltage V1 for∠60˚.( Initial set value of Max Torque angle shall be set ∠60˚ lagging angle. If Polarized voltage becomes lower than the Minimum polarized Voltage, phase direction control is lost and phase over current is not detected. On the other hand, if phase direction control is set for ‘NONE’, regardless of phase direction, phase over current is detected. Phase direction control type can be set in order to detect phase over current. Depending on control type, over current can be detected in Forward direction or reverse direction or regardless of direction. Following “Figure 7-9. Phasor Diagram for I1 Directional Polarization” shows normal current (I1) direction polarity phasor diagram in complex plane.

Ground direction is determined by comparing zero phase voltage (3V0) and zero phase current(I0). If an angle from zero phase voltage to zero phase current is within ± 90˚ based on Maximum Torque Angle, it is forward direction, otherwise, reverse direction. Maximum Torque Angle is between ∠0˚ and ∠359 ˚. Initial set value of max torque angle is set for ∠60˚ lagging compared with Zero sequence voltage(-V0). Polarized voltage drops Min. polarized voltage, ground direction control is cancelled and ground over current is not detected. On the other hand, if ground direction control is set for ‘NONE’, ground over current is detected regardless of direction. Ground direction control type is set to detect ground over current.

7.1.15. Overvoltage (59) In case that nominal voltage is kept higher than a certain voltage for a certain time, two overvoltage elements makes a trip operation. Overvoltage element is set in Primary or Alternate setting group. It is available to select a number of phase to be checked for overvoltage function. When the circuit breaker is closed by a local/remote controls, the overvoltage element is disabled from detecting for the cold load pickup during periods. To increase security, all overvoltage elements add two power frequency cycle of intentional delay to prevent incorrect operation.

Overvoltage 1 Setup The overvoltage 1 should be enabled to the following settings. PRIMARY, ALTERNATE or EITBANK SETTING / VOLTAGE / UNDER/OVER VOLT1 / OV1 Func’ [UNDER/OVER VOLT1] >OV1 Func’: OFF >OV1 Pickup: 1.10 [OFF/TR/AL/TR&AL]

If function = OFF, the feature is not operational. If function = Trip, the feature is operational. When the feature asserts a TR condition, the device trips. If function = AR, the feature is operational. When the feature asserts a AR condition, the device gives the alarm. If function = Trip & AR, the feature is operational. When the feature asserts a TRIP & AR condition, the device trips and gives the alarm.

7.1.23. Other Element 7.1.23.1. Sequence Coordination When several Reclosers are connected in series to protect distribution systems, ETR300-R contains Sequence Coordination feature which can prevent the simultaneous trip operations in both of Backup and Down-line Reclosers due to phase/ground fault. Sequence Coordination feature is activated only if one out of several Down-line Reclosers connected to one Back-up Recloser detects a fault current. The following rules should be kept to activate Sequence Coordination feature. 1) The same characteristics of fast and delay operations in the total number of the trip operations and identical basic Time Current Curves should be set for all Reclosers connected in series. 2) The identical reclose interval time should be set for all Reclosers in series. 3) To coordinate the protection characteristics, an additional delay operation time (at least 100 ms) should be applied to the Time Current Curve characteristics of Back-up Recloser, not to those of Down-line Reclosers. 4) The reset time of Back-up Recloser should be set longer than any reclose interval time of all Down-line Reclosers. This setting will prevent the reset operation of Back-up Recloser during the reclose operation of Down-lines. The Sequence Coordination feature should be enabled to the following settings. PRIMARY, ALTERNATE or EITBANK SETTING / OTHER ELEMENT / Seq' Coordi' [ OTHER ELEMENT ] >Seq’ Coordi’: OFF L.O Priority: GND [OFF/ON]

Range

OFF, ON

Default OFF

Step

Sequence coordination offers the function of preventing unnecessary operation of the backup recloser when two more reclosers are connected in series. If function = OFF, the feature is not operational. If function = ON, the feature is operational.

226

ENHANCED TECHNOLOGY



As shown in “Figure 7-36. Sequence Coordination Operation Block Diagram”, if Sequence Coordination feature at Back-up Recloser is enabled and a phase/ground fault occurs in distribution systems, the Back-up Recloser operates timing counter by overcurrent elements. During the count at the Back-up Recloser, if the distribution system is restored to normal by TRIP with Down-line Recloser , the number of the trip operations of Back-up Recloser is increased one step. Back-up Recloser performs trip operation instead of activating Sequence Coordination feature at the last sequence of the full sequence. If Auto Reclose switch is set to one TRIP, Sequence Coordination function can not be operated.
