Power Quality Troubleshooting Training

Power Quality Troubleshooting Training

This Power Quality Troubleshooting Training course will help to maximize industrial productivity and help to solve problems faster and reduce electrical equipment downtime.

Establishing preventative maintenance programs is becoming critical to maintaining the uptime of electrical equipment and can significantly reduce both planned and unplanned downtime. Unplanned downtime costs are difficult to calculate, but often significant. For some industries, it can represent 1 to 3 per cent of revenue (potentially 30 per cent to - 40 per cent of profits) annually.

The course will review equipment necessary to perform a Site Survey, such as industry oscilloscopes and Multimeters, Power Quality Analyzers, Current Clamp meters, and Mini Infrared Thermometers.



  • Learn how to perform insulation tests, insulation voltages, plus a wide range of DMM tasks with confidence and ease. Necessary for work on motors, cables and switchgear.
  • Learn how to accurately measure AC current without breaking the circuit
  • Check for hot spots and measure temperature with the Mini non-contact thermometers.
  • Measure voltage level, current balance, harmonics, power, energy, power factor, displacement power factor, determine bad or marginal circuit breakers, “K” factor, Crest factor.


WHO should attend

Design engineers, electrical engineers, commissioning and testing engineers, consulting engineers, electrical technologists, project managers, project engineers, plant managers, operating and maintenance personnel and all individuals involved in electrical equipment maintenance, testing and commissioning project execution.
