Note the following information: Check the shipment for completeness on the basis of the shipping documents. Store the parts in a dry place until installation. The product must remain in its airtight, protective wrapping and may only be removed immediately before installation You will find more information in the "Packaging, transport, and storage" chapter On-load tap-changer Function description On-load tap-changers are used to adjust the transmission ratio of transformers without interrupting the load flow. Fluctuations in voltage occurring in the power transmission grid, for example, can therefore be compensated for. For this purpose, on-load tap-changers are fitted in transformers and connected to the active part of the transformer. A motor-drive unit which receives a control impulse (e.g. from a voltage regulator) changes the operating position of the on-load tap-changer, as a result of which the transformer's transmission ratio is adapted to the prevailing operating requirements.

24 3 Product description 3.4 RS protective relay Function description The protective relay is used to protect the on-load tap-changer and the transformer when a malfunction occurs in the diverter switch oil compartment or selector switch oil compartment. It is tripped when the specified speed of oil flow from the on-load tap-changer head to the oil conservator is exceeded due to a fault. The flowing oil actuates the flap valve which tips over into position OFF. The contact in the dry-reed magnetic switch is thereby actuated, the circuit breakers are tripped, and the transformer is de-energized. The protective relay is part of an oil-insulated on-load tap-changer and its properties conform to IEC publication of the valid version. Therefore, it is part of the scope of our delivery. Diverter switch operations at rated switching capacity or at permissible overload will not cause the protective relay to trip. The protective relay responds to oil flow, not to gas accumulated in the protective relay. It is not necessary to bleed the protective relay when filling the transformer with oil. Gas accumulation in the protective relay is normal Front view Setup/models of protective relay Figure 9: RS Inspection window 24 VACUTAP VV /00 EN Maschinenfabrik Reinhausen GmbH 2015

26 3 Product description The protective relay RS 2003 and RS 2004 has a 1/2"-14NPT adapter in place of the cable connection (position 7) Pressure monitoring device DW Function description The DW 2000 pressure-operated relay protects the on-load tap-changer from unacceptable pressure increases, contributing to the safety of the transformer. The pressure-operated relay is installed on the outside of the on-load tap-changer and is tripped by unacceptable static and dynamic pressures in the on-load tap-changer oil vessel. The pressure-operated relay works on the same principle as a barometric corrugated tube with a counter-pressure spring and a mechanically linked snap-action switch. The sensor on the snap-action switch snaps to the other position by itself after tripping and has to be reset into the initial position by hand. The pressure increase activates the sensor on the snap-action switch that flips into the OFF position. This triggers the circuit breaker and de-energizes the transformer. Low-energy interference does not cause the pressure-operated relay to trip since the required tripping pressure is not reached. The tripping pressure is set at the factory and prevented from being changed. The pressure-operated relay responds faster than the RS 2001 protective relay in relation to large pressure increases. The RS 2001 protective relay is part of the default MR protection system that comes standard. Additional use of a pressure-operated relay also requires installation of the provided RS 2001 protective relay. The features and characteristics of the pressure-operated relay comply with the respective applicable version of IEC publication Diverter switch operations at the rated switching capacity or permitted overload do not cause the pressure-operated relay to trip. The pressure-operated relay responds to a pressure change and not to gas accumulation under the pressure-operated relay. Gas accumulation under the pressure-operated relay is normal. 26 VACUTAP VV /00 EN Maschinenfabrik Reinhausen GmbH 2015

27 3 Product description Structure/versions of the pressure-operated relay This chapter gives you an overview of the structure of the pressure-operated relay. The pressure-operated relay consists of a pressure measuring element and an adjacent snap-action switch. Figure 12: Snap-action switch and pressure measuring element 1 Snap-action switch 2 Pressure measuring element The snap-action switch has a normally open switch and normally closed switch with snap action. During operation, the snap-action switch and pressure measuring element are protected by a cover cap. Ventilation is provided on the top of the pressure-operated relay.

29 4 Commissioning transformer at installation site 4 Commissioning transformer at installation site Before energizing the transformer, check that the motor-drive unit and protective relay are functioning correctly and fill the on-load tap-changer oil compartment with new mineral insulating oil. Proceed as follows: 4.1 Checking motor-drive unit Before commissioning the transformer, repeat the function tests on the motor-drive unit as described in the operating instructions "TAPMOTION ED". WARNING NOTICE NOTICE Danger of death or severe injury! Danger of death or severe injury due to incorrect operation! Under no circumstances is the transformer to be commissioned if the functions are not satisfied in accordance with the Function tests section. Damage to the on-load tap-changer and motor-drive unit! Damage to on-load tap-changer and motor-drive unit due to condensate in the motor-drive unit! Always keep protective housing of the motor-drive unit tightly closed. If the standstill time before commissioning exceeds 8 weeks or operation is interrupted for longer than 2 weeks, the heater must be connected and turned on to prevent the condensation of moisture inside the protective housing. If this is not possible (e.g. during transportation), place a sufficient amount of dehydrating agent in the protective housing. Damage to the on-load tap-changer and motor-drive unit! Damage to on-load tap-changer and motor-drive unit due to incorrect use of position transmitter equipment! Only circuits stated in the chapter Technical data for position transmitter equipment of the operating instructions "TAPMOTION ED" may be connected to the position transmitter module connections. The switchover point of the position transmitter equipment in the motordrive unit is not the same as the switchover point of the diverter switch operation. This depends on the type of diverter switch. This fact should be noted when project planning the locking circuits between the motordrive unit and external equipment (e.g. transformer circuit breaker). For external monitoring, locking, and control purposes, it is not therefore the position transmitter equipment but the "Tap changer in operation" position transit contact shown in the connection diagram that should be used.

32 4 Commissioning transformer at installation site NOTICE Damage to the on-load tap-changer! Damage to the on-load tap-changer by actuating the on-load tap-changer without oil! Before actuating the on-load tap-changer for the first time, the tap selector must be completely immersed in transformer oil and the oil compartment completely filled with oil. The on-load tap-changer can be operated in the temperature range of the surrounding transformer oil of between -25 and +105 C and with overload up to +115 C in accordance with IEC Establish a connecting lead between the pipe connection E2 and one of the pipe connections R, S or Q to ensure equal pressure during evacuation in the oil compartment and transformer. Figure 14: Connecting lead 2. Fill on-load tap-changer with new mineral insulating oil for transformers in accordance with IEC using one of the two free pipe connections of the on-load tap-changer head. Figure 15: Pipe connection S and R 3. Take oil sample from oil compartment. 32 VACUTAP VV /00 EN Maschinenfabrik Reinhausen GmbH 2015

33 4 Commissioning transformer at installation site 4. Record temperature of oil sample just after sample is taken. 5. Determine dielectric strength and water content at a diverter switch oil temperature of 20 C ± 5 C. The dielectric strength and water content must comply with the limit values provided in the appendix [ 44]. 6. Bleed the on-load tap-changer. 7. Carry out tap change operation tests. 4.5 Commissioning the transformer 1. Loop the signaling contact for falling below the minimum oil level in the on-load tap-changer's oil conservator into the tripping circuit of the circuit breaker. 2. Loop protective relay and additional protective devices (e.g. pressure relief device) into circuit breaker's tripping circuit. 3. Ensure that all stop-cocks between on-load tap-changer and oil conservator of the on-load tap-changer are open. 4. NOTICE! Switch on transformer. Once the transformer has been switched on, ensure that the inrush current impulse has fully subsided before undertaking an on-load tap change operation. The inrush current impulses are usually a multiple of the transformer rated current and can overload the on-load tap-changer during the diverter switch operation. ð After the transformer has been switched on and the inrush current impulse has subsided, on-load tap-changer tap-change operations can be performed both under no load and load conditions. During all function checks and tests when commissioning, in addition to the safety instructions in Chapter 2, also note the safety notice provided in the chapter Electrical high voltage tests on the transformer.

Only actuate the motor-drive unit with the hand crank fitted in the motor-drive unit. Otherwise, there is a risk of serious injury. The safety switch in the hand crank disconnects the motor circuit at two poles however, it does not disconnect the control circuit. Only actuate motor-drive unit with hand crank to center. NOTICE! Only actuate the motor-drive unit with the hand crank in an emergency provided that the motor-drive unit has been correctly centered. Failure to do so may result in damage to the on-load tap-changer and transformer. An emergency should be understood to be failure of the motor-drive unit's voltage supply when there is an urgent need to perform a tap change. NOTICE! It is essential to complete all started tap changes without changing direction of rotation. The tap change is complete when the indicator is in the mid-position of the area marked in gray on the tapchange indicator. Failure to do so may result in damage to the on-load tap-changer and transformer. 5.2 Monitoring during operation WARNING NOTICE Danger of death or severe injury! Danger of death or severe injury from explosive gases under the on-load tap-changer head cover, in the pipework system, in the oil conservator or at the dehydrating breather opening! Ensure that there are no naked flames, hot surfaces or sparks (for example caused by static charging) in the immediate surroundings and that none occur. Damage to the on-load tap-changer! Damage to the on-load tap-changer! Make sure that the contact that indicates that the oil has fallen below the minimum oil level in the on-load tap-changer's oil conservator was looped through to the tripping circuit of the circuit breaker and that the circuit breaker will immediately de-energize the transformer when the oil falls below this minimum oil level in the oil conservator. Make sure that the protective relay RS and additional protective devices (e.g. pressure relief device MPreC ) were looped through to the tripping circuit of the circuit breaker and that the circuit breaker will immediately de-energize the transformer when the protective relay or additional protective devices have been tripped. 34 VACUTAP VV /00 EN Maschinenfabrik Reinhausen GmbH 2015

35 5 Operation Monitoring the on-load tap-changer and motor-drive unit is limited to occasional visual checks of on-load tap-changer head, protective relay, and motor-drive unit. For efficiency reasons these visual checks can be combined with the usual checks on the transformer. Pay particular attention to the following: Oil impermeability at the sealing points of the on-load tap-changer head, protective relay, and connected pipes Gaskets of protective housing of motor-drive unit Correct functioning of installed electrical heater in protective housing of motor-drive unit Correction function of protective relay (see) Perfect condition of the silica gel breather for the on-load tap-changer oil conservator The insulating oils in the transformer, including the on-load tap-changer, are to be monitored by the operator following the appropriate rules and regulations. The oil quality of the on-load tap-changer oil should be checked at regular intervals: For on-load tap-changers used on the neutral point of windings (class 1 in accordance with IEC ): every 7 years For on-load tap-changers used at points other than the neutral point of windings (class 2 in accordance with IEC ): every 2 years To do so, proceed as follows: 1. Take oil sample from oil compartment. 2. Record temperature of oil sample just after sample is taken. 3. Determine dielectric strength and water content at a diverter switch oil temperature of 20 C ± 5 C. The dielectric strength and water content must comply with the limit values provided in the appendix [ 44]. Maschinenfabrik Reinhausen GmbH /00 EN VACUTAP VV 35
