We have 2 no. 4MW DG set. and GEB supply.
But, we running, only 1 DG set. when we done APFC/Power
factor setting : 0.90, then winding temp. Low. but when
setting done : 0.83, then Winding temp. increase.
WHY Why ? ? ?, plz give me answer.
Answer Posted / suthan prabhu
The reacive power taken by the load will be same but the
current supplied by the source will increase bcoz the p.f
is decreased from 0.9 to 0.83.hence the winding temperature
increased.
