Answer Posted / jitesh kotecha
induction motor is an inductive device and we know that in
inductive circuit current lags behind voltage due to the
inductive reactance of the motor. so that the phase angle
between voltage and current will increase. and the cosine
angle i.e. P.F. will decreases.to improve the p.f we have
to supply leading Kvar to the system. it is possible by
different way. either use capacitor bank which will supply
leading kvar to the syswtem and overall lagging kvar will
decreases and if we see the power triangle then the angle
between KW and KVA will decrease so that the p.f. will
improve. second method is to run synchronous motor on
leading p.f.in parallel with the system.

1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2.
