How to Reduce Motor Load Current with a Capacitor Bank
Power Factor correction by capacitor bank installation will reduce the current consumption of a particular motor. I have a motor with the followings specs: 225kW 300HP 2965rpm. FLC 358Amp @ 415V 50Hz PF 0.94. During pump performance test, my motor was running at 420Amps ( short time ) but we still unable to get the required pressure for the pump.
Capacitor bank selection
Any technician with minimum electrical knowledge can determine or calculate reactive power compensation. The most common practice is using "a single" electricity bill. The emphasis here is on the "single" electricity bill as it is precisely here that a series of errors can start, which can often end up, with higher costs than those involved when a capacitor bank is correctly determined.
