What is Hi-Pot Test for Grid Station HV Equipments?
Answer Posted / shao
Thank you so much Naresh!
But i think we only measure the respective leakage current at that phase on which we have applied voltage.?
e-g; Applied 40KV at Red phase for 60sec, & measured leakage current was 0.6micro Amperes.
Actually im seeing this testing at a 132KV Grid Station.
