thought this video was a good overview of transformer winding resistance testing

Nice Post. And you just opened up the world of good Omicron vids for me. Thanks

Thanks for this Video Sir Sanjayo. .

I'm going to have a winding test this March 24 for a 3MVA transformer. . .

The criteria for this is Less than or equal to 2.00% difference between phases?

I will be using DV Power Winding Ohmmeter... .


Thanks. . .
