Power factor power factor is the cosine of the Angle between the active power (kW) and apparentpower (kVA) in a circuit.
功率因数功率因数是电路中有功功率(w)视在功率(VA)间夹角的余弦值。

In an electric power system, the following parameters often need measuring: voltage, current, power factor, power, reactive power and apparentpower.
电力系统中常需测量电压、电流、功率因数、有功功率、无功功率和视在功率等参数。

The output power is very stable after the temperature cycling and vibration test. No apparentpower decrease has been observed as the device working continuously for 500 h.
