why surge suppressor in vaccum circuit breaker and it is
only in motor feeder why not in tranformer feeder?no surge
suppresor in ocb in motor feeder?
Answer / kalyan dilip
Surge Suppressor is used to control the current
fluctuations.In motor there will be fluctuations in current
with the change in load. So Surge Suppressor is used in motor.
In case of Transformer there will no fluctuations in current
with the change in load because voltage is maintained constant
therefore it is not neccessary to use Surge Suppressor in
Transformer Feeder.

Dear Sirs, I am a technical persons.In one of our Electrical Sub- Station, We have installed three numbers of 1250KVA ,11KV/0.415KV Transformer to feed the Factory load. We have found some abnormality. In one of our Transformers the leakeage current from transformer body to earth through earth continuity wire is almost 86 Amp but in other transformer it is (5-10)Amp. where the load current on three phase and neutral are respectively 1360Amp,1400Amp,1370 Amp & 176Amp. So please any technical person help me about the reasons of this situation and how I can rectify the fault. Moreover,I have measured the earth resistance of the Earth continuity wire which is less than 1 Ohm. Thanks Tapas Barua
suppose if oil in transformer is not used than what constructional change you will do,for insulation and cooling?
