Answer / senthil kumar
we can able to test ac or dc. thats manufactures chosen.in ac hi-pot leakage current will be more(mA).but DC hi-pot leakage current will be less. but dc voltage charge the capacitance. in ac hi-pot we are applying 2V+1X 0.8 in dc hi-pot 2V+1X1.414X 0.8.

Yes, we can.
For test voltage we have to apply 80% of factory test
voltage i.e. 80% of 70 kv ac (factory test voltage) =56 kv
for 1 min.
