for testing busbar (33kv) hi-pot .whether we can apply DC r
not.and what is the test volt for that .explain
Answer Posted / 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.
