NettetA high power factor indicates that the power supplied to the electrical system is effectively used. A system with low power factor doesn’t effectively consume the incoming electric supply and results in losses. There is no power factor involved in DC circuits due to zero frequency. But, in AC circuits, the value of power factor always lies ... NettetThe answer depends on how you define "low." If the desired power factor for the power distribution system is 0.95, anything below that could be considered to be "low." By that definition, the power factor of a squirrel cage induction motor is "low" at light and heavy loads. If you compare the power factor at rated load with the power factor at ...
