Hi-pot test used for the measurement of leakage current
thrugh the cable and measure the capacitance beatween the
pahse to earth.

Answer / tanmay kumar

hi-pot done for power cable i.e ht cables...to calculate how much leakage current is flowing from conductor to earth...e.g-if we are test a 6.6k.v ht cable hi.pot testing then we have to provide a dc current of 2n+1's 80% to the conductor.

Will it be OK to connect a 5MVA 33/6.6kV Ynd11 Transformer to a Star connected Motor. Or on other words connecting a Delta to a Star. I have another 30MVA 33/11 Dyn11 and would it be practical to convert it to Dd0 consequently converting the Voltage Ratio to 33/6.35kV Dd0.
