The growth of power converters in equipment such as renewable generation and electric vehicle chargers has led to a build-up of electromagnetic interference (EMI) in the 2-150 kHz range. These frequencies are above the traditional power quality range, which is used to regulate emissions of equipment connected to the public electricity supply. The lack of emission limits in the past has resulted in increased EMI related malfunction of mass market goods as well as premature aging of connected consumer and professional equipment. The lack of measurement infrastructure in the 2-150 kHz range is hindering the ability to regulate emission in this frequency range and this workshop will explore the challenges and progress toward a framework for PQ measurements.
The project
EMPIR project Grid measurements of 2 kHz - 150 kHz harmonics to support normative emission limits for mass-market electrical goods (18NRM05, SupraEMI) was initiated to define a new normative measurement method for the 2-150kHz frequency range and associated R&D.
The workshop
This workshop will present outcomes and results at the halfway point in this three-year project.
