Fundamentals of Harmonics Webinar

This four hour seminar teaches the fundamentals of harmonics, including harmonic distortion and its causes, problems associated with harmonics and practical limits for harmonic distortion. The seminar teaches methods to identify, reduce and to avoid harmonics problems.

Upon completion of this course, participants should have a meaningful understanding of harmonic voltage and current distortion, the impact that harmonics can have on electric power systems, the typical causes and methods to avoid or minimize harmonics.

This course is applicable to electrical industry professionals serving either industrial or

commercial environments.

For maximum benefit of this course, participants should have an understanding of basic electrical principles such as Ohms law, power, electrical metering, motors and general electrical equipment and systems and a working knowledge of basic algebra.
