21) Tank earthing terminal and connector – two numbers, to provide double earth connections as required in the Indian Electricity Rules and suitable for connecting 4/0 copper wire of overall dia. 13.41mm.

22) Buchholz relay of suitable size double float type with one set of contacts for alarm and the other set for trip, complete with shut – off valve on conservator side and flange couplings,. The contacts shall be wired up to the marshalling kiosk with weather proof cables in metallic conduits. A testing pet cock shall also be provided.

23) Dial type winding hot spot temperature indicator WTI for each winding with three mercury switches responsive to the combination of top oil temperature and winding current complete with the required current transformers on the main windings, image coils, temperature detectors, oil capillary tubing for measuring the hottest spot winding temperature, heater resistors, etc., to be mounted on the transformer cubicle. The contacts of the WTI will be used for remote alarm and tripping and shall be wired up to a terminal block in the transformer marshalling kiosk. The WTI shall have inter-phasing with two outputs of 4-20MA, one output connected to repeater and another to SCADA.

24) Repeater for WTI for mounting on the main control board, working as an extension from the dial type WTI with a switch to connect either of the WTI’s for the measurement of the winding temperature of HV or LV at a time would be supplied.

25) Tank mounted/Floor mounted weather proof and vermin proof marshalling box with hinged door and padlock for housing control equipment and terminal connections.

26) Rating, diagram and terminal marking plate.27) Valve schedule plate.28) Off circuit tap changing gear.

3.13.00 PROTECTION:The transformers are supplied with inbuilt protection as are required for the satisfactory operation. These protections will generally comprise detecting and actuating devices for external alarm/tripping for the following conditions:i) Buchholz alarm and trip for incipient faults.ii) Oil and Water flow Indicators with one contact for alarm.iii) Low and high oil level for the transformer conservator for alarm.iv) Thermal alarm and trip for both oil and winding temperature.v) Necessary thermal overload relays for oil motors.vi) Pressure relief device with trip contact for transformers.vii) Overall Differential protection and restricted earth fault

protection.

3.14.00 POWER SUPPLY TO AUXILIARIES:

3.14.01 A.C. supply to auxiliaries shall be 3ø, 4 wire, 50 cycles + 3/-5%, 415/240V ± 10%, with grounded neutral from the station auxiliary

transformer. All electrical equipments such as motors, heaters, illuminating lamps, etc., would be suitable for the above A.C. supply.

3.14.02 DC power supply shall be at 110V ± 10%, from the switch yard battery through DC auxiliary switchboard. All indicating lights, alarm and trip devices shall be suitable for the above D.C. supply.
