Power factor is the percentage of actual useful energy obtained from an electrical device as opposed to the wasted energy lost to impedience of a circuit. ie heat, voltage drop. Improvement is to raise this percentage to as close to 100% as possible.

Improving power factor does nothing to improve a circuit. It merely affects the amount of current drawn by the load.

Can we improve generator power factor for increasing active power?

The 0.8 Power Factor provided by generator manufacturers is not the load power factor, but it is the nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output. Alternators are therefore designed to supply their rated kVA at 0.8 lagging power factor.


How select the rating of capacitor with respect to KW for improving power factor?

The capacitors must be sized according to the reactive power being used, not the real power being used, to improve power factor.


Is it possible to transmit power with leading power factor?

The power factor depends on the properties of the load, and if any power factor correction is done it has to happen at the load, so that the current in the transmission lines is reduced. Correcting the power factor at the sending end fails to address the problem.
