Grid measurements of 2 kHz -150 kHz harmonics to support normative emission limits for mass-market electrical goods

The build-up of product emissions in the supraharmonic frequency range of 2-150 kHz, threatens to cause malfunction of other electrical products, power line communications, and critical infrastructure.

The overall aim of the SupraEMI project is to develop new normative measurement techniques to enable regulation of interference caused by mass-market electrical products. Unlike other frequency ranges, the supraharmonic band has no effective regulation or normative measurement framework. This project will work with standards committees to develop a new measurement framework to facilitate the setting of realistic and credible supraharmonic interference limits and enable the regulation and compliance testing of mass-market goods.
