why induction motor always operate at lagging p.f.?..

Answer / gaurav

Induction motor always operates at lagging power factor
because induction motor is a electrical machine in which
only stator is supplied and rotor gets its power through
mutual induction.In the rotor how much current lag behind
the voltage is actually depends on the material used for
rotor.

we have one pumping station and 4.6 MW 7 no.s synchronous motors.so there is no required HT capacitor to improve power factor.But we have two no.s of 25 Mva power transformer connect to distribute the power for motors connect with 220 kv line.So i have required the HT capacitor to improve power factor at HT side i mean power transformer bus side.So please suggest how much HT capacitor banks required for same.
