HARMONICS & POWER QUALITY

INTRODUCTION

The Power Quality and Harmonic Analysis Seminar combines extensive field measurement and study experience to familiarize attendees with the terminology and concepts to evaluate power quality. The effects of harmonics on various power system components and methods of reducing excessive harmonics will also be addressed. IEEE recommendations, National Electric Code requirements and Canadian Standards Association are also emphasized in this course.

OBJECTIVES

This course is designed to enable participants to:

1. Describe various equipment used for power monitoring.
2. Recognize the cause and source of power system disturbances.
3. Explain how to mitigate any existing and potential problems, thereby minimizing equipment disoperation and process downtime.
4. Analyze types of electrical systems loads and their power quality considerations.
5. Calculate harmonic voltages and currents
