Continuous ‘Hands Off’ Insulation Resistance Testing of Critical Motors, Paper360º January/February 2020

For decades, pulp and paper plant personnel have performed insulation resistance tests with handheld megohmmeters to prevent motor failures that lead to costly unplanned shutdowns and re-winding repairs, yet these tests only provide a “snap-shot” of motor health. In only a few days, motor windings and cables exposed to moisture, chemicals, contaminants, or vibration can become compromised and fail at startup.

Portable megohmmeters also require electrical technicians to manually disconnect the equipment cables and connect the test leads on potentially energized or damaged equipment to perform the manual testing. These tests expose technicians to potential arc flashes when they access the cabinet. In the United States, non-fatal arc flash incidents occur approximately 5 to 10 times per day, with fatalities at the rate of approximately one per day.
