Organization: IEC
Publication Date: 1 February 2016
Status: active
Page Count: 38
ICS Code (Electromagnetic compatibility in general): 33.100.01
scope:

This part of IEC 61000, which is a Technical Report, provides definitions of various electrical power quantities and the relationship between them under non-sinusoidal conditions, in order to give clear information on both components in the power factor: the fundamental power factor, which is due to the phase difference between the voltage and current at the fundamental frequency, and the non-fundamental power factor, which is related to the distortion of the voltage and/or current. This Technical Report is applicable only to singlephase systems.

This Technical Report provides definitions for the three following cases:

• the general case where the voltage and current are both distorted (Clause 5),

• the case where the voltage is assumed to be sinusoidal and the current is only distorted with harmonic components (Clause 6),

• the particular case where the voltage and current are both sinusoidal (Annex A).

Annex B gives information on the fundamental active factor, which is used to describe the behaviour of a piece of equipment as a load or a generator.
