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”
