Fundamentals of Harmonics Seminar – 4 Credit Hours
Power Quality Seminars Approved by Wisconsin Department of Safety and Professional Services DSPS Course ID # 17383
For a strong power quality foundation – attend both The Power Factor Seminar (March 9) and The Fundamentals of Harmonics (March 10)
Fundamentals of Harmonics Seminar is a four hour seminar which 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. Register for this seminar by sending this PDF to PFMA.
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.
