Description: Overhauling of 11KV Breaker and LT panel with allied works at ISLS IV AA I under NTK Project Name of Work Overhauling of 11KV Breaker LT panel with allied works at ISLS IV AA I under NTK Project
Details: For HT panel :Thorough testing and calibration of 11KV VCB 3 Panel distribution board at site:A) Disconnection of 11KV HT cables.B) Cleaning of entire panel by carbon cleaner to remove all carbon particles.C) Cleaning of all dismantled components to remove all carbon particles and sulphation to improve insulation resistor (IR).D) 11KV Breaker completely servicing, cleaning by CRC & checking of all parts and make it in proper condition.E) Cable and termination to be cleaned by carbon cleaner.F) After servicing of all switch gear & checking its IR with respect to earth and phase to phase, they are racked in service position & kept at ON condition. At this condition High Voltage testing.G) All over current and earthfall relays tested by secondary injection.H) IR value checking of PT & CT.I) Tripping test of Breaker by primary injection.J)After testing all the HT cables (11KV) reconnected for successfully charging of 11KV supply on put on load condition. For LT PCC panel :A) Thorou
