For 11kv suppy it is 40kv/2mm at normal temprature is ok. As per my experience it is reach upto 125kv/2mm at 40°c after filtration but we keep it 60kv/2mm NB-Below 24kv/2mm is rejected oil.

at meter room 50 hrc switch installed,but there are not get earthing proper,so what happen?and 11kv transformer out put going in to hrc main 400a three nog each? so earthing is require for all switch? (some customer made earthing at there home.)
