1、no-load apparent power
2、rated apparent power on line side
3、The power factor (pf) is the ratio of average power to apparent power.
4、In an electric power system, the following parameters often need measuring: voltage, current, power factor, power, reactive power and apparent power.
5、Power Factor Power factor is the cosine of the angle between the actie power( kW) and apparent power( kA) in a circuit.
