what role neutral plays in electrical circuit? If neutral is not there what will be the effect
1 3953IN MY SYSTEM THERE IS ONLY OVER CURRENT EARTH FAULT RELAY IS AVAILABLE. FOR THE UNBALANCE SENSING IS THERE ANY RELAY IS AVAILABLE? THE SAME CTs WHICH ARE USED FOR THE OVER CURRENT EARTH FAULT RELAY CAN USE FOR UNBALANCE ALSO?
2 3166Could u pls tell me the NPCIL electrical engineering interview questions for Executive trainee, and also guide me how to face the interview.
3862if there is nutral in phase why we use earthing wire and grounding? even at fault condition the fault current flows to neutral (it is a lower path)
1323How much the fault level of 11 k.v.,22 k.v., 33 k.v. (in Maharashtra- M.S.E.D.C.L) for calculation of short circuit current & selection of h.t.cable.
1 5893I have a question, I visit 01 site and face a problem, there is 2.5 ton Air Con working, when air con compressor is running at that time rectifier voltages are increasing upto 290-295 v and rectifier is giving main high alarm (rectifier is APC single phase, before starting compressor rectifier voltages was 230v. when air con is going off rectifier voltages are decreasing smoothly at its actual voltages 230v. Load on Genset phases is this: Red-13.5 amp AC (Air Con load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp AC (telecom system load), Genset phase to phase and neutral to phase voltages are also ok. These are 10 sites having same system and same rectifier APC brand at every site 02 genset are working but the problem is same at all these 10 sites. What will be the reason behind???
