Practical Power System Harmonics, Earthing and Power Quality - Problems and Solutions

THE WORKSHOP

The power system harmonics, earthing and power quality workshop is a comprehensive, highly practical and interactive course dealing with the various types of power quality problems that have a wide ranging effect on the power systems equipment and apparatus in any plant. You will have the opportunity to learn and discuss the fundamentals of power quality problems such as surges and voltage sags. Other problems having wide ranging effects on power system equipment such as voltage swells, voltage fluctuations, supply interruptions, frequency variations, harmonics and noise shall also be discussed in detail. Issues related to control of the occurrence of these problems by appropriate system design and mitigation of the effects of these by adoption of appropriate protective measures and by the addition of power conditioning equipment shall be discussed. Also, aspects related to designing of the systems, proper installation practices, analysis of the probable reasons and corrective measures will be discussed in detail. Practical examples from actual projects will be used extensively to illustrate the principles and drive home the point.

The material is covered by means of an interactive lecturing style, with plenty of practical examples and realistic case studies derived from real work performed in this area
