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”

What is Short Circuit Analysis, and Why is it Done?
Published by Carelabs (Carelabz), Website: carelabz.com A Short circuit analysis is used to determine the magnitude of short circuit current, the system is capable of producing, and compares that magnitude with the interrupting rating of the overcurrent protective devices (OCPD). Since the interrupting ratings are based by the standards, the methods used in conducting a short circuitContinue reading “What is Short Circuit Analysis, and Why is it Done?”
