Power Quality and Harmonics
A two-day power quality course that explains the Engineering Recommendations associated with power quality, and demonstrates their application through worked examples and case studies.
This practical course will take you step by step through the Engineering Recommendation G5/5 on harmonics, explaining the background to the recommendation and the relevance of British and International standards to modern power networks.
The course will take you through the theory behind various types of disturbance on power networks, including the concept of electromagnetic compatibility, the causes and effects of harmonics, voltage fluctuations and flicker, and the effects of variable speed drives, UPS and switched mode power supplies.
You will then get the opportunity to test your understanding of G5/5 by working through a number of worked examples. Finally the workshop course will discuss power quality measurements and how the results can be interpreted, as well as the kind of power quality mitigation and conditioning techniques that you can apply.
