Here are some of the reasons behind -- and solutions for -- low power factor caused by motor loads
Improving power factor (PF) pays handsome dividends in the form of electric bill reductions, improved inplant voltage stability, more efficient utilization of the plant power distribution system, and deferral of capital investment in additional power distribution capacity. There are, however, some negative side effects if care is not exercised in compensating for low power factor caused by induction motors.
Power factor explained. All devices that operate on the principle of electromagnetic induction draw a reactive, magnetizing current component that lags the ...
