Answer / suthar bharat

using vector group of a 3ph tranformer ,we can say that ,it
defined different phase angle between primary winding and
secondary winding. Like ,different group 0',30',-30',180'..

How you calculating the current for a 2.5 Sqmm cable. A 30 Hp 3 phase AC motor of power what size of cable is used for this motor.

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.
