Could someone tell me the general approach for a problem of this nature or lead me to useful information.
Problem
A 415V, 50Hz, three-phase motor takes a line current of 15A when operating at a lagging power factor of 0.65. When a capacitor bank is connected across the motor terminals, the line current is reduced to 11.5A. Calculate the kVAR rating and the capacitance per phase of the capacitor bank for:
1) A star connection
2) A delta connection
Find also the new overall power factor.
Any response will be greatly appreciated.
