How to synchoronize the generator (with gcb,GT) to grid????? ????? from Grid iam getting power (rated 400kv/20kv) through GT and its goes to UAT.,,ST.,, now my generator(rated 20kv ) ready.,, now iam closing my GCB.,, in GT iam suddenly giving 20kv on that Gt.,, what will happend
2026WHY IS THE NO LOAD CURRENT SMALL FOR A TRANSFORMER COMPARED TO OTHER ROTATING ELECTRICAL MACHINES??
1 4328Three set (each phase contain 2 cable of 400 mmsq CU XLPE AWA) of single core cables are connected to 11 KV motor of 14 MW & the switch gear supplay is taken from 11kv feeder & this supplay taken from 275 KV substation. Problem is one pair cable(L3- 2 cable ) getting very hot & gland melted and damaged in switch gear side. the other two cable haven't any more hot(ambient temp only & L3 haveing 95- 100 Degree C. The same problem happened in 275 KV substation switch gear side also where the supply taken for 11 kv switch gear. But here L2 phese cable had problem. Why it is happening like this?. The cable having temperature different at different location from gland side inthe case of 11KV feeder of 275 kv substation. why ?
