Can you suggest what is more advantage or helpful in Transformer testing, doing insulation resistance test or insulation power factor test.
Thank you.

Power factor test set = $$$
Insulation resistance test set = $
Hiring a competent testing contractor to show up and do the tests usually means you get BOTH tests anyway. They are part of a pretty standard battery of tests on oil-filled transformers above a certain size.
