IEC/TR 61000-1-4 Ed. 2.0 en:2022

Electromagnetic compatibility (EMC) - Part 1-4: General - Historical rationale for the limitation of power-frequency conducted harmonic current emissions from equipment, in the frequency range up to 2 kHz

IEC/TR 61000-1-4 Ed. 2.0 en:2022

Electromagnetic compatibility (EMC) - Part 1-4: General - Historical rationale for the limitation of power-frequency conducted harmonic current emissions from equipment, in the frequency range up to 2 kHz.

IEC TR 61000-1-4:2022 is available as IEC TR 61000-1-4:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC TR 61000-1-4:2022, which is a technical report, reviews the sources and effects of power frequency conducted harmonic current emissions in the frequency range up to 2 kHz on the public electricity supply, and gives an account of the reasoning and calculations leading to the existing emission limits for equipment in the editions of IEC 61000-3-2, up to and including the fifth edition (2018) with Amendment 1 (2020), and in the second edition of IEC 61000-3-12.

The history is traced from the first supra-national standard on low-frequency conducted emissions into the public electricity supply, EN 50006:1975 and its evolution through IEC (60)555-2 to IEC 61000-3-2, IEC TR 61000-3-4 and IEC 61000-3-12. To give a full picture of the history, that of the standard for the measuring instrument IEC 61000-4-7 is mentioned as well.

NOTE All IEC standards were renumbered starting from 60000 from 1998-01-01. To indicate the references of standards withdrawn before, or not reprinted after, that date, the “60x” prefix is here enclosed in parentheses. Hence “IEC (60)555-2”.

Some concepts in this document apply to all low voltage AC systems, but the numerical values apply specifically to the European 230 V/400 V 50 Hz system.

This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

  • relation between compatibility levels, emission limits and immunity requirements clarified;
  • sharing of emission levels between LV, MV and HV clarified;
  • new historical information added.
