About the Event

Power quality is of utmost importance to electrical engineers, since it can greatly affect power system performance, design requirements, and project costs. Power system engineers have dealt with power quality issues for decades, and yet, despite this knowledge and experience, power quality still poses a challenge to daily system operations.

Seminar Description

The Power System Harmonics and Power Quality course is designed to help attendees understand the causes, effects, and methods of addressing various power quality problems. The course presents study approach, field measurement, and monitoring programs to familiarize attendees with the definitions and concepts used to evaluate power quality. The course introduces methods of modeling and simulating power systems for study purposes, and these methods are demonstrated using case studies of actual power quality problems. The effects of harmonics on various power system components and methods of reducing excessive harmonics will be addressed as well. Power quality and harmonics standards, IEEE recommendations, and NEC and CSA requirements are also emphasized in this course.

The main course objectives are to:

  • Understand the basic principles of power quality and its impact on electrical systems and equipment;
  • Know how power quality is measured and analyzed;
  • Obtain an overall understanding of the applicable standards (IEEE, NEC, CSA, etc.); and
  • Apply sound design techniques to new or existing installations.

Who Should Attend?

This course is designed to familiarize power system engineers dealing with planning and operating power systems, as well as managers responsible for power quality monitoring programs.


Basic knowledge of power system analysis.

Course Methodology

This is a practical course in which participants focus on power quality concepts and complete exercises using typical case scenarios. The course will include formal presentations and discussions, as well as practical examples based on real-life problems.
