BS EN IEC 61000-4-30:2025

This standard BS EN IEC 61000-4-30:2025 Electromagnetic compatibility (EMC) is classified in these ICS categories:

• 33.100.99 Other aspects related to EMC
• 17.220.20 Measurement of electrical and magnetic quantities

IEC 61000-4-30:2025 defines the methods for measurement and interpretation of results for power quality parameters in AC power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method’s implementation. This document addresses measurement methods for in-situ measurements. This document covers two classes of measurement methods (Class A and Class S). The classes of measurement are specified in Clause 4. NOTE 1 In this document, “A” stands for “advanced” and “S” stands for “surveys”. Measurement of parameters covered by this document is limited to conducted phenomena in power systems. The power quality parameters considered in this document are power frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage interruptions, transient voltages, supply voltage unbalance, voltage harmonics and interharmonics, rapid voltage changes, mains communicating system (MCS) voltages, magnitude of current, harmonic currents, interharmonic currents and current unbalance. Emissions in the 2 kHz to 150 kHz range are considered in Annex C and Annex D. Depending on the purpose of the measurement, all or a subset of the phenomena on this list can be measured. NOTE 2 Test methods for verifying compliance with this document can be found in IEC 62586-2. NOTE 3 The effects of transducers inserted between the power system and the instrument are acknowledged but not addressed in detail in this document. Guidance about effects of transducers can be found IEC TR 61869-103. This fourth edition cancels and replaces the third edition published in 2015. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition: a) IEC 61000-4-30:2015/AMD1:2021 and IEC 61000-4-30:2015/COR1:2016 were included. b) The measurement method for rapid voltage changes (RVC) has been corrected and extended. c) The measurement method for voltage events has been updated and extended. d) Annex C was divided into 2 parts: 1) Annex C: The measurement method from IEC 61000-4-7:2002 and IEC 61000‑4‑7:2002/AMD1:2008, Annex B for conducted emissions in the 2 kHz to 9 kHz range has been separate 2) Annex D: A new measurement method for conducted emissions in the 9 kHz to 150 kHz range has been added. e) Annex D (underdeviation and overdeviation parameters) was removed. f) Annex E (Class B) was removed.
