Partial Discharge Analysis for Transformer Insulation Testing

[EE4me]

TL;DR

I would like to know how to test turn to turn insulation.

I would like to test the insulation of a transformer using partial discharge analysis. Testing insulation between the primary and secondary is pretty straightforward. I short the primary as well as the secondary, apply voltage across the two, then take my measurements.

I also need to test the turn to turn insulation for the primary and the secondary using partial discharge analysis which I'm not sure how to do. Any help is appreciated.

I'm not an expert on that. But the first place I would look is this:
