Power Quality Standards

Published by Mark McGranaghan, Electrotek Concepts, Inc. Electrical Contractor Magazine, Power Quality for the Electrical Contractor Course Introduction Power quality has always been important. However, for many years the equation defining power quality was very simple: POWER QUALITY = RELIABILITY Customer loads were linear in nature. When a sinusoidal voltage was supplied to them, theyContinue reading “Power Quality Standards”

The Need for Harmonic Modeling and Mitigation in Generator Applications: A Conversation and Guide

White Paper 08-03-2021 Published by Michael McGraw, USA National Sales Manager, Mirus International Inc., Introduction & Structure It is widely accepted that performing harmonic studies for non-linear applications is important to ensure a workable and energy efficient installation. It is also accepted that these harmonic studies be performed under normal source conditions and maximum operatingContinue reading “The Need for Harmonic Modeling and Mitigation in Generator Applications: A Conversation and Guide”

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”
