Electromagnetic compatibility (EMC) – Part 4-37: Testing and measurement techniques – Calibration and verification protocol for harmonic emission compliance test systems - Edition 1.0; Includes Access to Additional Content
 N 61000-4-37

Annotation

This part of IEC 61000, which is a Technical Report, outlines a typical test procedure for harmonic analysis in systems comprising

• tests apparatus designed to comply with IEC 61000-4-7, and

• products designed to comply with IEC 61000-3-2 and/or IEC 61000-3-12.

The test procedure is intended to provide a systematic guidance suitable for use by manufacturers, end users, independent test laboratories and other bodies, for the purpose of determining the applicable compliance status within a wide range of harmonic current emissions.

The test procedure is derived from conditions observed in actual product testing and simulates closely conditions that can reasonably be expected.

The accuracy of harmonic analyzers and complete tests systems having adjustments or procedures, either hardware or software-based, may be optimized using external reference equipment of sufficient accuracy and the methodology in this Technical Report.

This Technical Report is not intended as a replacement for type testing of harmonic analyzers, nor does it check all of the parameters specified in IEC 61000-4-7, IEC 61000-3-2, and IEC 61000-3-12.
