What is Power Factor?

Power factor is the ratio of real power (kW) to apparent power (KVA). This ratio can be a value from 0 to 1, and it indicates how efficiently an AC circuit is using electricity, with a value of 1 representing high efficiency. The third type of power, called reactive power (KVAr), causes electronics to be inefficient and draws the ratio closer to 0 by creating a difference between real power and apparent power.
