WebPower factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period. It is found by multiplying (kVA = V x A). The result is expressed as kVA units. WebPF = cos φ. where. PF = power factor. φ = phase angle between voltage and current. The power factor defined by IEEE and IEC is the ratio between the applied active (true) power - and the apparent power, and can in general be expressed as: PF = P / S (1) where. PF = power factor. P = active (true or real) power (Watts)
