1.Summary

k1.0

1.1 General UniGear ZS2 is a three-phase, metal-clad, air-insulated switchgear and all the units are factory-assembled, type-tested and suitable for indoor applications up to 33 kV. The units are designed as withdrawable modules and are fitted with a single busbar system. Details of the technical design and configuration of individual switchgears, such as the technical data, detailed equipment lists for the individual panels and comprehensive circuit documentation etc., can be found in the relevant order documents. 1.2 Standards and specifications UniGear switchgear panels comply with the standards and specifications for factory-assembled, metal-clad and type tested high voltage switchgears to IEC publications 62271-200 and 62271-1.In addition, in accordance with IEC 60529, the switchgear panels have the following degrees of protection: IP 4X for the enclosure and IP 2X for the partitions.  All other corresponding IEC publications, national or local safety at work regulations and safety regulations for production materials must follow during erection and operation of these systems.  Above and beyond this, the order-related data from ABB must be taken into account.

1.3.2 Special operating conditions Switchgear are suitable for operation in the climate of Wda type according to IEC 60721-2-1. Special operating conditions must be discussed with the manufacturer in advance. For example: • At site altitudes above 1000 m, the effects of the reduction reduction in dielectric strength of the air on the insulation level must be taken into account (please refer to diagram in figure 1/1). • Increa Increased sed ambient ambient temper temperature atures s must be compensate compensated d for in the design of the busbars and branch conductors as well as for the withdrawable parts, otherwise the current carrying capacity will be limited. Heat dissipation in the switchgear panel can be assisted by fitting additional ventilation facilities. Note on any special climatic operating conditions: When switchgears are operated in areas with high humidity and/or major rapid temperature fluctuations, there is a risk of dew deposits which must remain an exception in normal operating conditions for indoor sw itchgear. Preventive action (e.g. fitting electric heaters) must be taken in consultation with the manufacturer to avoid this condensation phenomenon and any resulting corrosion or other adverse effects. The control of the heaters depends on the relevant project and details must be taken from the order documents.

The enclosure is completed above by top-mounted pressurerelief flaps which, according to the rated branch conductor current, are made of sheet steel with wire mesh or plain sheet steel. The pressure-relief flaps are secured with steel screw on one longitudinal side and on the other longitudinal side with plastic screws. In case of internal overpressure, the plastic screws are the point of rupture. The rear wall of the busbars compartment 84, intermediate wall 9, and mounting plate 12 with shutters 12.1/12.2 and horizontal partition 20, form part of the internal partitioning. The internal partitioning makes safe access to the circuit-breaker and cable compartments possible even when busbars are live.

3. Panel design and equipment 3 .1 Basic structure and variants (Figures 3/1 to 3 /3) The basis for the UniGear panel is the incoming/outgoing feeder panel with vacuum circuit-breaker using i nsertion technology. It is divided into busbar compartment A., circuit-breaker  compartment B., cable compartment C and control cabinet D for the secondary equipment. Apart from this, there are variants for all operating needs. Pictures 3 /1 show examples of possible configurations of a panel including electrical equipment. For busbar sectionalizing, two panels are necessary, the coupling panel with the withdrawable circuit-breaker part and a bus riser panel (optional with busbar metering and earthing). In equipment without busbar sectionalizing, a direct bar connection between the bus bars will be established. Further details about installation and equipping the switchgear can be obtained from the order documents. 3 .2 Enclosure and partitioning (Figure 3 /3) The enclosure and internal partitions of the panels are of 2mm thick high quality steel sheets. The three high voltage compartments (busbar compartment, circuit- breaker compartment and cable connection compartment) are equipped with top-mounted and secured pressure relief flaps. These open in the case of over pressure due to an internal arc fault. The front of the panel is closed by pressure resistant doors. Cable and circuit- breaker compartments have independent doors. The circuit - breaker compartment is equipped with inspection window made of security glass. Neighboring panels

On the end sides, cover plates ensure good appearance and are mechanically and thermally arc fault proof such as event occur in the end panel. Door and rear walls as well as the cover plates are thoroughly cleaned and treated against corrosion before receiving a high quality double coating of paint. The finishing coat is in the standard RAL 7035 colour (special colours by agreement). The circuit-breaker compartment and cable connection compartment doors are pressure resistant and can either fitted with screws or manual closing system. 3.2.1 Ventilation of the panels (figure 3/3, 6/20, 6/21) Openings in the outer enclosure are needed for the purpose of ventilation in the case of certain rated currents in the busbars and branch bars. For outgoing air, the pressure relief flaps 1.1 are made of expanded metal instead of flat steel sheets. The size and design of the vents in expanded metal provide the IP4X degree of protection. In cases of higher ambient temperature (>40 0C) and /or increased frequency (60 Hz) it may be necessary to provide additional cooling system. 3.3 Compartment in the panels 3.3.1 Bus bar Compartment (Figure 3/3, 5/18 to 5/20) The busbars 3 have tubular cross section made of copper and are laid in sections from panel to panel. According to the current rating, diameter and thickness of the busbars are changed. They are held by flat branch conductor 2. No special connection clamps are needed. Busbars and branch conductors are insulated & connections are shrouded. 3.3.2 Circuit-breaker compartment (Figure 3/3, 3/8, 3/9, 3/10, 3/11, 5/20, 6/22) The circuit breaker compartment contains all the necessary equipment for reciprocal operation of the withdrawable part and the panel. Like the busbar compartment, it is metallically partitioned on all sides. The tulip isolating contacts 5. together with the fixed isolating contacts, are located in mounting plate 12. the metal shutters12.1/12.2 covering the insertion openings, are also included. The shutters are opened by means of actuating bars

into the service position, and are closed when the latter is removed. In the test/disconnected position of the withdrawable part, partitioning by separation is established in the main current circuit. Connections of the control wiring, required for the test purposes, need not be interrupted when in the test/disconnected position. In the test/disconnected position, the withdrawable part is still completely inside the panel with door closed. The ON/OFF pushbutton located on the circuit-breaker, and the mechanical indicators for ON/OFF and CHARGED/DISCHARGED can be observed through an inspection w indow. The switching operations are carried out with the doors closed. Installation of an additional mechanical switching device for manual operation of the circuit-breaker in the service position is also possible (see Fig. 3/14, 3/15). The socket 10.1 for the control wiring is mounted fixed in the circuit breaker compartment. 3.3.3 Withdrawable parts (Figure 3/3, 3/12, 3/13, 3/16 to 3/19, 3/25) 1. Withdrawable circuit breaker parts The withdrawable circuit breaker forms a complete module consisting of the VD4 type circuit breaker. The withdrawable assembly 13 and the circuit breaker are coupled via a multi-pole control wiring plug connector 10. The withdrawable assembly establishes the mechanical connections between the panel and the circuit breaker. The fixed part is connected to the panel by forking, which is form coded on both sides. The moving part with the circuit breaker is moved manually by means of a spindle, between the service or test/disconnected positions with the front doors closed. Service and test disconnected positions are set precisely by means of auxiliary switches, which resister the final position reached and the angular position of the spindle. The earthing connection between the withdrawable part and the panel is established by its roller and travel rails which are bolted on to the panel. On request separate earthing provision for circuit breaker in test and service condition is available. Withdrawable parts of the same design parameters are interchangeable. In the case where withdrawable parts have the same dimensions, but different circuit breaker fittings, the control wiring plug coding prevents any erroneous connections between the withdrawable part and the panel. 2. Other withdrawable parts (Figure 3/3, 3/21) The withdrawable part can also be fitted with the following trucks:  – Metering voltage transformers trucks with fuses.  – Earthing truck without making capacity (for main busbar system and power cables);  – Earthing truck with making capacity (for main busbar system and power cables)  – Power cable testing trucks;  – Isolation trucks;  – Isolation truck with fuses. 03.3.4 Cable connection compartment (Fig. 3/3, 5/41) The cable compartment contains current transformers 7, fixed and withdrawable voltage transformers 8 and earthing switch 6,

The voltage transformer mounted fixed are connected on the primary side with suitable connectors.The removable voltage transformers are fitted with HRC fuses. The EK6 type earthing switch can be used with either a manual or motor-operated mechanism. Its switching position will be indicated both mechanically and electrically by means of the auxiliary switch.

Cable connections: In the 1000mm/1200mm panel, up to three parallel cables can be connected with single-core cable of maximum cross section of 630 sqmm. 3.3.5 Low Voltage compartment (Fig. 3/3, 3/7, 5/20, 5/39) The control cabinet is for all control and protection aspects, suitable for both conventional or microprocessor control technology. The height of the control cabinet 460 mm for details see chapter  2.3. If the secondary devices are not intended for door installation, they are mounted inside the low voltage compartment. They enable any subsequent changes to the wiring. Secondary wiring inside the panel is in a duct on the right side of the panel. The left side of the panel is for the external wiring. The ducts are covered with steel sheet metal 3.4 Interlock/protection against erroneous operation 3.4.1 Panel Internal interlocking (Figure 3/3) To prevent the hazardous si tuations and erroneous operation, there is a series of interlocks to protect both personnel and equipment: • The withdrawable part can only be moved from the test/ disconnected position (and back) when the circuit breaker  test/disconnected position (and back) when the circuit breaker and earthing switch are off (i.e. the switch must be off before hand). In the intermediate position, the switch is mechanically interlocked. When the circuit-breakers have an electrical release, the interlock is also electrical. • The circuit breaker can only be switched on when the withdrawable part is in the test or service position. In the intermediate position, the switch is mechanically interlocked. When the circuit breakers have an electrical release, the interlock is also electrical. • In panels with digital control technology, prevention of malfunction of the switch can also be achieved by means of the panel software. • In the service or test positions, the circuit-breaker can only be switched off manually when no control voltage is applied and it cannot be closed (electromechanical interlock). • Connecting & disconnecting the control wiring plug 10.2 is only in the test/disconnected position of the withdrawable part. • The earthing switch 6 can be switch on if the withdrawable part is in the test/disconnected position or outside of the panel (mechanical interlock 1). • If the earthing switch is on the withdrawable part cannot be moved from the test/disconnected position to the service position (mechanical interlock). • Details of the other possible interlocks e.g. in connection with a locking magnet on the withdrawable part and/or earthing

3.4.2 Door interlocking (Figure 3/4-1 to 3/4-8) The panels can be equipped with the following interlocks: • The circuit breaker cannot be racked-in if the apparatus compartment door is open (3/4-1 and 2) • The apparatus compartment door cannot be opened if the circuit breaker is in service or in an undefined position (3/4-3 and 4) • The earthing switch cannot be operated if the cable compartment door is open (3/4-5 and 6) • The compartment door cannot be opened if the earthing switch is open (3/4-7 and 8). 3.4.3 Interlocks between panels The busbar earthing switch can only be closed when all the withdrawable parts in the relative busbar section are in the test/disconnected position. When the busbar earthing switch is closed, the withdrawable parts in the earth busbar section cannot be moved from the test/disconnected position to the service position. 3.4.4 Locking devices (Fig. 3/3, 6/13, 6/22 ) • The shutter 12.1/12.2 can be secured independently of each other with padlocks when the withdrawable circuit-breaker  part has been removed. • Access to the operating-shaft 14.1 of the earthing switch can be restricted with a key lock. • Access to the circuit-breaker racking slot can be restricted with a key lock. • Access to the circuit breaker compartment and the cable

Figure 3/1 -1Cross Sections of 36 kV panel

compartment can be with a padlock. 3.5 Control wiring plug connector coding (Figure 3/25) The control wiring plug connector coding allows withdrawable parts for switching devices to be assigned to particular panels This ensures, for example, that withdrawable parts with different rated current or different control wiring circuits can only be used in the panels they are intended for. Coding pins are fitted in the control wiring socket 10.1 or control wiring plug 10.2 and engage with the corresponding bores of the relevant plug 10.2 or socket 10.1 when the two parts are connected. The plug connector coding is order related and is noted in the relevant wiring documentation 3.6 Fast recovery (Figure 3/5-1 to 3/5-4) UniGear switchgear can optionally be equipped with “Fast Recovery”, a specific protection system. This system is based on pressure sensors 3/4-1, suitably located in the switchgear and directly connected to the shunt opening release installed in the circuit-breaker operating mechanism 3/4-2. The sensors detect the pressure rise front at the moment of an internal arc and promptly open the circuit breaker. Thanks to the “Fast recovery” system, only the part involved in the fault is selectively excluded in under 100 ms (including the circuit-breaker opening time). Rapid elimination of the fault along with the metal segregation between compartments and the use of self-extinguishing materials drastically reduces any possible damage.

4. Dispatch and storage 4.1 Condition on delivery  At the time of dispatch, the UniGear panels are factoryassembled, the withdrawable parts are in the test position and the doors are closed. The factory-assembled panels are checked at the works for completeness in terms of the order and simultaneously subjected to routine testing (normally without AC voltage testing of the busbars) to IEC publication 62271-200, and are therefore tested for correct structure and function. The busbars are not assembled. The busbar material, fasteners and accessories are packed Separately unless mentioned. 4.2 Packing The panels are packed for transportation to destination in following types.  Panels with basic packing or without packing.  Panels with seaworthy or similar packing (including packing for containerized shipments): - Sealed in polyethylene sheeting - Transport drying agent bags included - Moisture indicator included  Observe the directions for use of the drying agent bags. The following applies: - Coloured indicator blue: contents dry - Coloured indicator pink: contents moist (relative humidity above 40%). 4.3 Transport (Figure 4/1) The transport units normally comprise individual panels and, in exceptional cases, small groups of panels. The panels are each fitted with four lifting lugs. Transport panels upright. Take the high centre of gravity into account. Only ever carry out loading operations when it has been ensured that all precautionary measures to protect personnel and materials have been taken and use the following:  Crane  Fork-lift truck and/or   Manual trolley jack. Loading by crane:  Fit lifting ropes of appropriate load capacity with spring catches (eyebolt diameter: 30 mm)  Keep an angle of at least 60° from the horizontal for the ropes leading to the crane hook.  Hang the unit using ALL four eyebolts!

4.4 Delivery The responsibilities of the consignee when the switchgear  arrives at site include, but are not limited to, the following:  Checking the consignment for completeness and lack of any damage (e.g. also for moisture and its detrimental effects). In case of doubt, the packing must be opened and then properly resealed, putting in new drying agent bags, when intermediate storage is necessary.  If any quantities are short, or defects or transport damage are noted, these must be: - documented on the respective shipping document. - notified to the relevant carrier or forwarding agent immediately in accordance with the relative liability regulations. Note:

4.5 Intermediate storage Optimum intermediate storage, where it is necessary, without any negative consequences depends on compliance with a number of minimum conditions for the panels and assembly materials. 1.Panels with basic packing :   A dry well-ventilated store room with a climate in accordance with IEC 60694.  The room temperature must not fall below -5 °C.  There must not be any other negative environmenta influences.  Store the panels upright.  Do not stack panels.  Panels with basic packing: - Open the packing, at least partially. 2. Panels with seaworthy or similar packing with internal protective sheeting:  Store the transport units: - protected from the weather, - in a dry place, - safe from any damage.  Check the packing for damage.  Check the drying agent (also see section 4.2): - on arrival of the consignment, - subsequently at regular intervals.  When the maximum storage period, starting from the date of packing, has been exceeded: - the protective function of the packing can no longer be guaranteed, - take suitable action if intermediate storage is to continue 4.6 Unpacking Optimum intermediate storage, where it is necessary, without any negative consequences depends on compliance with a number of minimum conditions for the panels and assembly materials. Warning: Do not walk on the roof of the panels (rupture points in pressure relief devices!). The pressure relief devices could be damaged. The packing is intended for transport and not for storing purpose. Upon receipt the switchgear must be unpacked and installed under clean, dry, dust-free, indoor conditions and anticondensation heaters should be connected. The cubicles which are without vacuum packing are normally fixed to the pallet. The palette is suitable for lifting by fork-lift from all four sides provided that the width and length of transport palette is fitting. If the packing includes vacuum bags they might be used for storage indoors or under shelter for a period of time adapted to the ambient conditions. Packing for storage purpose can be supplied upon specific request

CAUTION! The center of gravidity may vary according to apparatus installed in panels. Assure that the panel is not damaged, tilted or dropped. The lifting beam in fig: 2.3.3 is not included in the delivery. Consider min 1.5 ton lifting capacity for each 1000mm cubicle.

5. Assembly of the switchgear at site In order to obtain an optimum installation sequence and ensure high quality standards, site installation of the switchgear should only be carried out by specially trained and skilled personnel, or at least by personnel supervised and monitored by responsible persons. 5.1 General site requirements On commencement of installation on site, the switch-room must be completely finished, provided with lighting and the electricity supply, lockable, dry and with facilities for ventilation. All the necessary preparations, such as wall openings, ducts, etc., for laying the power and control cables up to the switchgear must already be complete. Where switchgear panels have topmounted structures for earthing switches or instrument transformers, it must be ensured that the ceiling height is sufficient for the opening travel of the pressure relief plates. The ceiling must be high enough for assembly of pressure relief duct. Compliance with the conditions for indoor switchgear according to IEC 62271-1/ IEC 60694, including the conditions for the "minus 5 indoor" temperature class must be ensured. 5.2 Foundations (Figures 5/1 to 5/3)

4.38/2

Fig: 4.3.8 Circuit Breaker Lifting arrangement

5.2.1 Checking of foundation (Refer fig. 5/1) Check the foundation with respect to the foundation drawing supplied. The foundation frame on which the cubicles are to be installed must be properly leveled. The level difference more than the 1mm is not permitted. Refer figure for details. Level is to be checked using a water level. 5.2.2 Mounting of first cubicle on foundation frame. Start installation of cubicle from anyone side. The cubicle when dispatched from company is pallet mounted. It should be unloaded from the pallet as close as possible to the foundation frame position so that less movement is required after the cubicle is on the ground. Once the cubicle with pallet is on the ground, the same is to be pushed with manually on the foundation frame. If the use of the crowbar is unavoidable, the crowbar is to be inserted either on sides or on rear of the cubicle. Do not insert the crowbar in the front side of the cubicle. Please insure that the cubicle, when mounted on the frame is vertical. If necessary, use shim to make the cubicle vertical.]

Recommended tightening torque Nm  Lubricant CAUTION! The encapsulating sheet steel of cubicles may have sharp edges inside and on the roof. Before erection the highest point of the floor is identified. The erection begins with the left hand cubicle which is placed in level with the highest point. The cubicles are trestled if necessary in the front, at the back and the middle along the switchgear. This is made by one or more layers of thin steel plates. If the cubicle will be mounted against the w all make sure that the bolts for the rear cover are tightened before fixing the cubicles. See also 4.4 & Fig 4.5 before the next cubicle is installed. Next cubicle can then be installed and aligned and adjusted to the first one. Tighten the cubicles with bolts in the fitting holes close to the front and rear sides. The fixing is made by M8X25 bolts. Remaining cubicles should be erected in the same way.

1) The rated tightening torques for fasteners without lubricationis based on a coefficient of friction for the thread 0.14 (the actual values are subject to an unavoidable range, in part not inconsiderable.) 2) Rated tightening torques for fasteners with lubrication in accordance with DIN 43 673 standard. 3) Thread and head contact surface lubricated.  Any tightening torques which deviates from those in the general table (e.g. for contact system or device terminals) must be taken in account as stated in the detailed technical documentation. It is recommended that the threads and the head contact surface of the bolt should be lightly oiled or greased, so as to achieve a precise rated tightening torque. The individual installation stages are as follows  Remove the withdrawable parts from the switchgear panels and store them with suitable protection.  Dismantle lifting eyebolts  Transport the switchgear panels to the prepared installation point following the sequence shown on the switch gear plan.  Release and remove floor cover 5.17  If any top-mounted enclosures or instrument transformer have been removed for transport, bolt these in place in the specified position where the rear and middle pressure relief plates would otherwise be located on the switchgear panels and make the internal connections again. (Figure 5/28, 6.2.3/4).   Align the switchgear panel on the floor frame for correct positioning and vertical alignment (deviation of the panel edges from the vertical must not be exceed 2 mm. especially at the front) and bolt the panels together. It is advisable to start from the centre when assembling switchgears with more than ten panels.  When the switchgear has been properly assembled, fix the panels to the concrete floor using plugs, or weld or adequately bolt them to the foundation frame. 5.4 Installation of the busbars

Fig 4.4 5.2.3 Mounting of second, third… cubicles on the frame Follow the procedure described 5.2.2.When the second cubicle is placed on the foundation, it must be pushed as close as possible to the first cubicle so that two cubicles touch each other from top to bottom. Do not weld other cubicles on frame till all cubicles are erected and busbars are couple 5.3 Assembly of switchgear panels (Figure 3/3, 5/15 to 5/42)

CAUTION! The encapsulating sheet steel of cubicles may have sharp edges inside and on the roof.  Access possibilities for the main busbars installation are shown on the below figure, they are: -side access during installing the adjacent cubicle -removable roof plate -removable rear cover + rear plate of the main busbar compartment It is advisable that the busbar erection is done in parallel with the cubicles erection when access to the main busbar compartment is available from side. The insulated main busbars, and tee-boots are delivered loose in each respective

Fig 5.3.2 Access for main busbars installation The insulated busbars must be protected against damaging of the insulation. Damaged insulation must be renewed. The PVC protective with air cushion will protect the insulated parts from damages also during transport and installation period. Keep them on the busbars as long as possible until commissioning. Busbar assembly work requires cleanness as the dielectric strength will be decreased by metal dust etc.

CAUTION! The encapsulating sheet steel of cubicles may have sharp edges, be careful ! All cubicles have a copper bar for the earth system. The main earth bar is placed at bottom of cubicle under the earthing switches. Those bars should be bolted together and the station earth system shall be connected to through earth bar. Conical washers to ABB standard 9ADA334 must also be used throughout the earth bar connections. The bare earth bar and the cubicle steel plates must not "just touch" either must be fixed with an air gap or bolted as connection. Copper bars used for earth connection to the Aluzinc plate must be greased "type E" to avoid galvanic corrosion. The earth main bars have standard length.

5.7 Cable connection 5.7.1 Power cables (Figure 5/18, 5/19, 5/41) The standard method for the entry of power cables in the switchgear is shown in Fig.5/18 and 5/19. the cables are conveyed from below through floor covering 17, which is divided at the cable entry point. The cables go through rubber cable glands, which can be adapted to the required cable diameter. Cables are fastened in the panel by means of clamps mounted on cable strips, which are part of the panel floor covering. The clamps make it possible to fasten cables. Cable sealing ends are mounted on the cable cores according to the manufacturer's instructions. It is possible to use cable sealing ends of different manufactures (e.g. Raychem) but it is necessary to keep the length of the cable ends, including cable sealing ends, which is given by the distance of cable connecting bars 23 from the panel floor covering. These bars have different versions. Which differs in there number of parallel cables and the values rated and short-circuit currents. See fig. 5/41, 5/42. The bars are equipped with the holes for M16 screws. If M12 screws are used for cable connections, special washers with the diameter M12 screws are supplied. In all cases, the earthing of cable screens is carried out on the strip-holding cable clamps. The cable strip is connected to the earth potential. It is also possible to place the removable arrangement of voltage transformer in the cable compartment. These can be fitted with HV fuses similar to those in the measuring panel. Three fixed mounted surge arresters can also be installed here. But in both these cases the number of parallel cables must be reduced. Note: The cable glands are not in scope of ABB.

6.3 Test Procedure 6.3.1 Testing the off-circuit condition Switchgear panels which are not equipped with capacitive voltage indication, checking the off-circuit condition is carried out with a HV tester on the contact pin, after the corresponding upper shutter or lower shutter has been opened. If the panels are equipped with capacitive voltage indication, checking the offcircuit condition can be carried out by means of this device. In this case, proceed according to the manufacturer's instructions or the indicators. (Optionally, switchgear can be equipped with various types of indicators coming from various manufacturers). In case of any doubt about correct operation of capacitive voltage indication, the off-circuit condition must be checked using a HV tester. CAUTION! Checking the off-circuit condition must

6.3.2 Current and voltage tests (Figures 6/16, 6/19) The testing and earthing module 142 is available for carrying out current and voltage tests. It is also suitable for supplying primary current to any current transformers which may be fitted during measurements in the protection circuit and, for example, for application of a test voltage during insulating tests.  Isolate and secure the working area in accordance with the IEC safety regulations.  For primary current supply, fix the connecting cable of the test transformer to the contact pins 142.7.  For AC voltage tests, ball 142.4 is required on the contact pin. The bore in the ball is used for connection of the voltage supply.  For current tests, for example of small connected generators, the short-circuit bridge 142.8 must be fixed onto the contact pins. Note: With voltage tests at power frequency withstand voltage and/or impulse voltage, carry out the following procedure:  Disconnect any voltage transformers and capacitive dividers and cover them with an insulating plate. 6.4 Service Trucks Instead of earthing, short-circuiting and testing with module 142 it is possible to use the service trucks. These trucks are divided into four different types: Earthing truck without making capacity These trucks carry out the same function as the earthing switches without making capacity. Therefore they do not have any capacity to earth the live circuits under fault conditions. They are used to ensure fixed additional earthing, as required by the plant service and maintenance procedures, as at further guarantee for personnel. The use of these trucks foresees removal of the switching device from the switchgear (circuitbreaker) and its replacement with the truck. The units preset for use of earthing trucks are fitted with a key lock which, if activated, prevents their racking-in. This truck is available in two versions:  main busbar system earthing;  Power cable earthing. During the racking-in phase, the main busbar earthing truck only lifts the top shutter and earths the contacts connected to the top branches (and therefore to the main busbar system) by means of the switchgear structure. During the racking-in phase, the power cable earthing truck only lifts the bottom shutter and earths the contacts connected to the bottom branches (and therefore to the power cables) by means of the switchgear structure. These trucks can also be used in the bus-tie units. In this case, they earth the two sides of the main busbar system.

7. Maintenance 7.1 General Maintenance serves to preserve trouble-free operation and achieve the longest possible working life of the switchgear. It comprises the following closely related activities: Inspection: Determination of the actual condition Servicing: Measures to preserve the specified condition Repair: Measures to restore the specified condition Note: When carrying out all maintenance work, the regulations in the country of installation must be strictly complied with. Maintenance work may only be performed in a careful manner by trained personnel familiar with the characteristics of the individual switchgear, in accordance with all relevant IEC safety regulations and those of other technical authorities, and with other overriding instructions. It is recommended that ABB service personnel be called in to perform the servicing and repair work detailed below. The inspection and servicing intervals for some of the equipment/components (e.g. parts subjects to wear) are determined by fixed criteria, such as switching frequency, length of service and number of short-circuit breaking operations. On the other hand, for other parts the length of the intervals may depend, for example, on the different modes of operation in individual cases, the degree of loading, and also environmental influences (including pollution and aggressive air). Operating instructions must also be followed, together with this instruction manual of the VD4. If necessary, further details can be taken from the technical documentation for the switchgear  Installation (including, for example, any special operating conditions agreed on). 7.1.1 Intervals for inspection, servicing and repairs Time intervals for maintenance work to be carried out always depend on the operating conditions of the switchgear, and mainly on the mode of operation, the number of rated and short-circuit current switching operations, ambient temperature, pollution etc. We recommend carrying out the maintenance work at the following intervals:

7.2 Inspection • Where necessary, the working area must be isolated and secured against reconnection in accordance with the Safety Regulations specified by IEC and appropriate national standards before inspection. • Correct condition of the switchgear should be monitored by regular inspections. • Under normal operating conditions, inspection should be carried out once every four years by specially trained professional electricians. • Under abnormal operating conditions (including adverse climatic conditions) and/or special environmental stresses (heavy pollution and aggressive atmosphere, among others), inspection may be necessary at shorter intervals. • Inspection is primarily to carry out a visual check for grime, corrosion and moisture: - Effects of high temperature on the main circuits, - Traces of partial discharge on the insulating material parts, - Traces of leakage current on the insulating material parts, - Surfaces of the contact systems. • However, inspection must also to include correct mechanical/electrical operation of the following parts: switching devices, actuating, interlocking, protection and signaling devices.

1) Under more demanding service conditions, we recommend shortening this interval appropriate – also sect. 7.1 and 7.2. 2) According to results of inspection. 3) See the instruction manual of the circuit-breakers.

Caution: instrument transformer circuit. With regard to the switching devices, their separate Instruction manual should be followed. Check all switchgear accessories and auxiliary devices (e.g. storage batteries). No partial discharge must occur on the surfaces of equipment at operating voltage. This can, for example, be detected by characteristic noises, a clearly perceptible smell of ozone, or visible glowing in the dark. Visually checking the contact system. We recommend to turn the contact system alternately in order to clean the inner contact points of the contact system. The contact points should be cleaned if signs of overheating (discoloured surface) are visible (see section 7.4). If any irregular conditions are detected, then relative repair measures must be taken.

7.3 Servicing If, during the course of an inspection in accordance with section 7.2, the need for cleaning measures has been established, proceed as follows: • Where necessary, the working area must be switched off and secured against reconnection in Accordance with the Safety Regulations specified by IEC and appropriate national standards before cleaning. • Clean the surfaces in general: - Weakly adhering dry dust deposits: with a soft dry cloth. - More strongly adherent grime: with mildly alkaline household cleanser or with ETHANOL F 25 M. • Clean insulating surfaces and conductive components with ETHANOL F 25 M. • Wipe down after cleaning, using clean water, and dry properly.

•

Should partial discharges occur as a result of condensation, application of a thin silicone film on the surface concerned is often effective as a temporary remedy. It is advisable to ask the ABB after-sales service department for advice regarding permanent solutions to this type of unusual problem.
