PD IEC/TR 61000-1-7:2016

This standard PD IEC/TR 61000-1-7:2016 Electromagnetic compatibility (EMC) is classified in these ICS categories:

• 33.100.01 Electromagnetic compatibility in general

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:

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

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

3. 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.
