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

The Megger MIT200 series of 250-V, 500-V and 1000-V insulation and continuity testers perform insulation testing to 1000 MΩ Continuity testing can be done at 200 mA down to 0.01 Ω. The testers include ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

With the new MCT1605 test set from Megger, comprehensive testing of current transformers – including multi-ratio types – can be carried out quickly and easily. With the new MCT1605 test set from ...
