What is the effect of leading power factor for power
transformer & D.G?
Answer Posted / om prakash
Leading power factor makes the current leading the voltage
it does not affect the transofmer but it affects the
D.G./Power generation unit. As for the power generation we
need to excite the excitor field which take the sensing
reference voltage from the output line of the generator.In
case of leading power factor the voltage will not dip on
increasing the load and hence the AVR will not be able to
excite the system properly.

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
