IEC Releases IEC TR 61000-4-37:2016, Technical Report on EMC Testing and Measurement Techniques

BinderThe International Electrotechnical Commission (IEC) has published IEC TR 61000-4-37:2016, a technical report on “Electromagnetic compatibility (EMC) – Part 4-37: Testing and measurement techniques – Calibration and verification protocol for harmonic emission compliance test systems.” It is now available for purchase on the IEC’s webstore.

Description*

IEC TR 61000-4-37:2016 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. It 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. This publication contains attached files in the form of an xls document and a user guide. These files are intended to be used as a complement and do not form an integral part of the standard.”

Mastering High Voltage: The Importance of Accurate Test Equipment

This whitepaper underscores that precise calibration of high-voltage test gear — especially when measuring 1 kV–150 kV systems — is essential for safety, reliability, and regulatory compliance. It details measurement techniques (voltage dividers, step-down transformers, etc.), the impact of environmental and connection factors on accuracy, and why traceable calibration (e.g. to NIST / A2LA) is a must to ensure consistent, reliable results.
