Ali Naderian, P. Eng.

Director, High Voltage Testing Services


T: 1.905.232.7300

I am a professional engineer with 20 years of experience in high voltage testing, condition assessment, and diagnostics. During my career, I worked in multiple high voltage labs to test outdoor insulators, cables, transformers, switchgears, CT/PTs, CVTs, terminations, motors, and generators. At METSCO,  I lead HV projects including commissioning, maintenance,  diagnostics, root cause failure, and condition assessment of MV and HV power apparatus.

I am an active member of the IEEE Transfor mer Committee, the IEEE Insulated Conductors Committee, the CIGRE working groups including A2/D1.51: “Improvement to Partial Discharge Measurement for Factory and Site Acceptance tests”.

I have published more than 50 conference and journal papers in the area of HV testing and condition assessment. I am  a senior member of IEEE and recognized reviewer of IEEE Power & Energy Society since 2009.

To give our clients a piece of mind by offering third party independent testing and condition assessment. HV testing and diagnostics is my work passion and I always like to be on top of the latest testing technologies within the R&D world to ensure our clients have complete access to the latest information on the state of their assets with limited budget and time.

I like to play tennis and football (the real one!). I also enjoy playing traditional drums at home when nobody is around. In the past five years, one of my volunteer works that I am proud of is to assist in educating new immigrants to settle and find jobs in Canada through different local organizations. Additionally, I volunteer my time by participiating in IEEE Dielectirc Insualtion, Toronto Chapter.
