We maintain the P.F. of DG Set approx 0.95 by two methods :-
1.By decreasing the voltage
2.By using power capacitor

Advantage is that for higher PF load current will be low to
deliver the same KW/MW from DG Set.

Can we use a absolute encoder to show rpm of a motor ? what about the condition when power is off ? what is difference if a incremental one is used ?abanirout@gmail.com
