Answer / gopi

synchronous generator can be operated in overexited at no
load condition. then it acts as a synchronous condenser.

Answer / dhivyabharathi

When it is over excited it will act as a synchronous
condenser. when the synchronous motor is over excited, it
will also act as the synchronous condenser.synchronous
condenser is like a capacitance.synch.condenser can be used
in power factor improvement.

Answer / praadeep_dd@yahoo.com

At peak load time Synchronous Gen. act as Synchronous
condenser. At peak load time the p.f. is very poor resulting
in low vtg at receiving end. Hence to feed reactive power to
inductive load the Synchronous Gen. is over excited. This
improves p.f. improving vts profile at R.E.

Answer / shariff

When a synchronous generator is overexcited and its terminal voltage becomes more than the supply voltage, then it will act as a generator.

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
