Electrical System Testing & Maintenance

It is taught in Lab This 5 day course has been taught continuously since 1981; it is 80% hands on and will teach your staff how to commission, inspect, test, troubleshoot, maintain and evaluate common electrical equipment. It is taught in Lab One 1, one of our fleet of mobile electrical training centers and is set up specifically for maintaining and testing electrical equipment.

Stored throughout the lab are three phase transformers, motors, circuit breakers, cables and other equipment. Students learn the failure modes of all of this equipment and each team of two students tests and analyzes the results on their own test specimens. Participants will be involved in a combination of classroom and hands-on labs which they can then apply to their own testing and maintenance programs.

These are pictures of the interior of our Lab One 1; the left picture is a view from the entrance. Down the right side are storage lockers for smaller test specimens and test instruments. The large black unit in the right foreground is a circuit breaker primary injection tester capable of producing 10,000 amps AC. Down the left side are 4 benches for two students each. Beside each bench is either a 15 kV vacuum or 15kV SF6 circuit breaker. At the far end is a 24 kV SF6 breaker, shown in the right picture. At the right side of it you can see a linear transducer permanently mounted to the breaker for time travel analysis.

Your equipment will also be incorporated into the training. If your equipment is not available for practical work then the instructor will explain the testing required for your equipment including examples and demonstrations. Our instructors have extensive experience with substation and plant electrical equipment and can address a broad range of systems. This course has been attended by engineers, electricians, technicians, technologists, supervisors, managers as well as instrument supervisors managing electrical departments.

To conduct the tests we provide our students with meggers, DC hipots, AC hipots, thumper,TDR’s, TTR’s, C&DF bridge, DLRO’s, primary injection testers, secondary injection testers, first trip breaker analyzers, protective relay testers, CT tester, breaker contact timers, time travel analyzer, winding resistance ohmmeters, winding impedance testers, winding surge tester, corona generator and detectors, oil sample syringes, valves, test tank and oil dielectric testers, clamp-on ground resistance tester, and ground resistivity testers. In addition to these test instruments that we bring, we also incorporate client test equipment into our training such as VLF hipots, Doble testers, partial discharge testers, PdMA and Baker testers, sweep frequency response analyzers, etc.

To ensure that your students are learning world class skills we reference the following standards in our training;
Canadian Standards Association: CSA Z463 – Guideline on Maintenance of Electrical Systems
InterNational Electrical Testing Association (NETA): ANSI/NETA 2011 Standard for Maintenance Testing Specifications; ANSI/NETA 2009 Standard for Acceptance Testing Specifications.
Professional Electrical Apparatus Recyclers League: Reconditioning Standards for Electrical Equipment, Components and Apparatus for Reuse in Commercial and Industrial Applications; Inspect & Test Standards for Electrical Equipment, Components and Apparatus for Reuse in Commercial and Industrial Applications. Institute of Electrical and Electronics Engineers: 3007.1-2010 – IEEE Recommended Practice for the Operation and Management of Industrial and Commercial Power Systems; 3007.2-2010 – IEEE Recommended Practice for the Maintenance of Industrial and Commercial Power Systems.
National Fire Protection Association: NFPA 70B – Recommended Practice For Electrical Equipment Maintenance.

Each student receives three comprehensive binders of reference material including maintenance frequencies, PEARL test standards and test forms as well as a copy of Paul Gill’s Electrical Power Equipment Maintenance and Testing, Second Edition.

The documentation received will enable you to develop a comprehensive maintenance program for your electrical equipment that exceeds the requirements of CSA Z463.  Additionally, as certified course developers, our courses are professionally designed to the standards of the American Society of Training and Development, the Canadian Society of Training and Development, as well as the International Board of Standards for Training, Performance and Instruction. We are also proud to be ISO 9001 certified.

Student Testimonials


“Fred was able to inform us of what tests to perform and the dangers and why we are performing. He shared a lot of great tips/advice and he had a great ability to convey his knowledge.”

Andrew MacGillivray, Syncrude

“This was a very informative course. I liked using the different test equipment and seeing how the different breakers work. The instructor, Fred Tanguay explains things well and definitely knows his stuff. I don’t like it when an instructor reads to you out of the text book, Fred doesn’t do that. I got a lot out of this course.”

Chris Doan, Koch Fertilizer ULC

“Fred is an excellent instructor, very knowledgeable with many years of experience. He took the time to explain in details and made sure that we understand everything.”

Gerry Favis, Suncor Energy

“I do believe Fred does a great, thorough job teaching this course. With his experience in his past jobs, it has brought forward a great way to bring his awareness and safety for us as a tradesman.”

Mike Lysohirka, Areva

“The course was very well presented and the class numbers work because the instructor was able to help each one of us out when needed. The equipment was good examples of different types of testing equipment, old and new. Very well organized instructor with a great sense of humour (thanks for that).”

M. Zwick, Mosaic Potash

"This was a valuable interpretation of control circuits, grounding and motor starters. I would recommend this course to other electricians. It had excellent content and the instructor was very knowledgeable."

Mark Capron, Shell Canada Ltd
