Hands-On Power Quality and Harmonics

Course Description

Nearly all electrical devices have power supplies that may cause a disturbance to the current sine wave of a power source. Most published surveys show that 65-85 of the power quality problems are the result of something happening within the facility, on the customer side of the point of common coupling. It may be the wiring or the loads themselves that make the supplied voltage incompatible with equipment within the facility. The result is that the process is interrupted, productivity is halted, and dollars are lost.

This Hands-On course combines extensive field testing and field 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.

Equipment Requirements
(This apply's to our hands-on courses only)

BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.
