EMC for 2 to 150 kHz: A proposal for emission and immunity of equipment including power-line communication

Published by Anders Larsson and Math Bollen, ELFORSK, Elforsk rapport 09:29, October 2008 Summary The frequency range from 2 to 150 kHz is not sufficiently covered in international standards. The contrast with the frequency range below 2 kHz is striking. There have traditionally been good reasons to emphasize on the lower frequency range, where theContinue reading “EMC for 2 to 150 kHz: A proposal for emission and immunity of equipment including power-line communication”
