Repairs/replacement of 200 KVA three Phase Servo Stabilizer installed at M and HED complex Shalteng srinagar..

Amount

Complete Servicing of 200 KVA Three phase servo stabilizer by way of dismantling of servo stabilizer, removal of core coil assembly from transformer oil tank by using chain pulley block. The job includes checking of servo motor (synchronizing motor) that rotates arm connected to the dimmer in proper direction according to input voltage and replacement of worn out or damaged carbon brushes. The job also includes checking the yellow, blue and red bus bar connections to the three phases. The job further includes checking and replacement of wires, voltmeter, terminals etc. and their checking and rectification for proper working and cleaning of cooling fins etc. The job also includes reassembling of the parts after repairs. All tools/ tackles and chain pulley block required for the job are shall be arranged by the contracting agency.

Dismantling of 03N0. damaged 300Amp Dimmer stat coils from the servo stabilizer by using skilled labour and shifting the same to workshop for repairs by way of removing of carbon and finishing / rewinding wherever necessary and refitting of the coils to the servo stabilizer and testing/operation of servo stabilizer on no load/Full load after repairs.

Providing and fitting of ML-10 contactor to give desired constant voltage in input voltage, avoiding frequent switching and ensuring stable system. The job includes providing and fitting of 25 sqmm single core copper wire (20meter) with thimbles and providing and fitting of High cut and low-cut card along with time delay system controlling fluctuations in input voltage/.

Providing and filling of transformer oil for 200 KVA Three phase servo stabilizer for topping up.

Providing and fitting of PCB digital card having an intelligent microcontroller to keep AC synchronous servo motor running, overload trips, low /high voltage trips, input and output voltage monitor etc.

Providing and fitting of Aluminum thimbles for 95sqmm cables in changeover switch (Four Pole ) and servo stabilizer replaced by the damaged thimbles
