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.
