The effects of conducted interference on static electricity meters

Online, 21 April 2021 at 10:00 – 12:30 CEST

This free of charge online workshop will present challenges and results from EMPIR project Electromagnetic interference on static electricity meters (MeterEMI, 17NRM02).  The three-year project aimed to resolve issues around reported errors on some makes of smart meter and define new testing procedures and equipment for possible future normative standards.

The project was set-up in response of the findings by the University of Twente in the Netherlands which reported some serious (>500%) meter errors induced by fast current changes.

During the workshop these effects will be discussed.  Also, speakers will present:

  • Results of further testing of meters carried out using waveforms captured from mass market electrical products,
  • Results of further testing of meters carried out using waveforms recorded on-site at meter connection points and
  • examples of captured waveforms and associated meter errors will be presented.


The characteristics of the current waveforms that cause errors will be presented, together with a toolbox of techniques that can be used to specify waveforms that can be used to test meters to check whether a particular design of meter give high errors. These waveforms will be applied using testbeds used in testing labs and the challenges and progress of developing/retrofitting suitable laboratory apparatus to test meters will be presented.

The project findings are expected to influence future normative standards and testing procedures and the outlook for future standardisation will be given.

Who should participate?

Electricity suppliers, meter manufacturers, market regulators, representatives of standards committees, consumer groups, EMC specialists, electrical metrologists.
