Learn how to test a transformer: insulation resistance, TTR, winding resistance, polarity, continuity, and dielectric checks.

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

Bob is a service technician who is well trained and nationally certified. However, he sometimes suffers from the same confusion that all technicians occasionally do — the facts that he gathers may or ...

Bushings are the most critical component of a low-voltage (LV) transformer. They are important to the transformer’s operation because they are active parts. Unfortunately, bushing failures are the ...

Omicron’s new Votano 100 is the first voltage transformer testing and calibration system to combine mobility (total weight less than 33 lbs /15 kg) with the highest level of accuracy (precise ...
