Answer / meenakshi

conductors are the substance that has mobile electrons which
moves from one atom to another CONSTANTLY(juz imagine line
of people passing the ball constantly as they get the ball
to their hand)..but semiconductors are those substance in
which the electrons does'nt move readily unless it is
doped(here distance between the people is large,so people
become lazy to pass the ball...this is case for undoped ..)

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.
