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”

Frequency Response of Instrument Transformers in the kHz Range

Published by Dr. Kerstin Kunde, Dr.-Ing. Holger Däumling, Dipl.-Ing. Ralf Huth, Dipl.- Ing. Hans-Werner Schlierf and Dr.-Ing. Joachim Schmid As the number of non-sinusoidal sources and loads in the network continues to grow, the importance of information concerning the quality of the current and the voltage becomes ever more important. Each deviation in frequency canContinue reading “Frequency Response of Instrument Transformers in the kHz Range”
