Two papers were presented to the Conference for Precision Electromagnetic Metrology (CPEM 2020).  One paper described a new real-time algorithm to measure supra harmonics in the frequency range 2-150kHz which will be used to measure conducted interference on the electricity network. This interference is often caused by renewable energy and EV power convertors which leads… Read More


The project presented a comparison of 2-150kHz measurement algorithms, reviewing them in terms of accuracy, reproducibility, and computational cost.  Methods of long term measurements were also discussed.  Various use cases were presented to categorize different types of emissions.… Read More


The project presented its initial ideas to IEC SC77A WG9 on power quality measurements. This committee is responsible for the redefinition of IEC61000-4-30 on power quality measurements and will include a new method for 2 to 150 kHz measurements as part of a new normative Annex C. The project team is now reviewing suitable algorithms… Read More


The project team has held a webinar for conveners of several IEC working groups to discuss the project objectives and to give the IEC experts an opportunity to influence the direction of the work of the project.… Read More
