how net resistance islow in star connection and viseversa in delta connection...? if anybody could explain in detail it wud be helpful.
How line capacitance & line inductance varies with increase in height tower.
Good day everyone,currently in our premise we using 30kw slip ring motor with resistance bank which we use as forward and reverse at conveyor bar handling. So,my question is how do we calculate the resistance bank which is suit the motor. Kindly,assist me... thank you
