Transformer test
Transformer test
(OP)
We have a three distribuiton transformer (1MVA 12.47kV/480V), and we would like to run different test to calculate the following
capacitances:
- Phase to Phase
- Primary to secondary
- Phase to ground.
I was wondering if anybody knows of any technique/procedure or circuit configuration that allows to measure such capacitances.

AVO/Megger also manufactures test equipment for testing capacitance or power factor/dissipation factor.
God bless!

As for phase to phase. I'm not sure if it would work, but if you can isolate the three windings you maybe able to do it. The test connection would be different.
