Answer / amit rajak

YES,
it has very important role in working of synchronous
machine or any electrical equipment or devices.

by power factor correction we balances the current and
voltage cosine angle and hence ultimately power factor
which is very neccesary for maximum efficiency of the
electrical machine

by balancing it we actually balancies the abnormalities
which is arising due to vatious faulty condition.

How is efficiency of DG set calculated? At many places I found the efficiency to be mentioned in percentage. But at some other places I found kWH/ litres. I want to know how dimensionless percentage value is arrived at?
