Power Quality Training for Electrical Professionals
Comprehensive 2 Day Power Quality Training for Electrical Professionals
This 2-day learning event offers a combination of classroom style seminars with live demonstrations in real world settings. This seminar, presented by the Power Quality Specialists at Allied Industrial Marketing, Inc., provides an in-depth study of both Power Factor and Harmonics.
This training program will be held at the Eaton Power Systems Experience Center (PSEC) near Pittsburgh, PA. The PSEC is a one of a kind electrical power quality demonstration facility with industrial, commercial and residential systems and equipment. This seminar offers an opportunity for power quality education in the latest technology facility, with theory and live demonstrations.
Participants will gain a working knowledge of both power factor and harmonics. The first part of the seminar explains the three types of power factor, from a cause and effect basis and then teaches the intricacies of each type along with the methods to improve each power factor. The seminar demonstrates the proper way to size power factor capacitors for various types of situations and the pitfalls to be avoided when applying capacitors.
The second part of the seminar explains harmonic distortion and its causes, and identifies problems associated with harmonics as well as limits (IEEE-519-2014) for harmonic distortion. Participants will learn methods to identify and to solve or avoid harmonics problems as well as methods to predict estimated levels of harmonic distortion. Live demonstrations plus real life examples reinforce the techniques learned to analyze distortion levels, evaluate alternative harmonic mitigation techniques or equipment and to quantify expected results.
Upon completion of this course, participants should have a meaningful understanding of both power factor and harmonics. The power factor session covers the various types of power factor, the impact that low power factor has on electric power systems and energy costs, the causes of low power factor plus methods to analyze and improve power factor. The harmonics session covers harmonic voltage and current distortion, the impact that harmonics can have on electrical power systems, the typical causes, simple methods to analyze harmonic distortion and methods to 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.
