Introduction to Harmonic Analysis Basics

COURSE NO: E05-009
Introduction to Harmonic Analysis Basics
Course Highlights

This online engineering PDH course provides an introduction to harmonic theory. It addresses various power quality phenomena, how electrical systems are modelled for the purpose of harmonic calculations and how harmonic filters are sized.


A harmonic-producing load can affect other loads if significant voltage distortion is caused. The general procedure is to first develop a model that can accurately simulate the harmonic response of the present system and then to add a model of the new addition. Only very small circuits can be effectively analyzed without a computer program. Typically, a computer program for harmonic analysis has the capability to predict the actual distortion based on models of converters, arc furnaces, and other nonlinear loads.


This 5 PDH online course is suitable for electrical engineers with a desire to understand the fundamentals of harmonic phenomena and power quality in general.
