1 3261When we are working on transformer(132\11KV). we are going to isolate the transformer from both HV side and LV side. then we are applying grounding on both side. My question is that we required to isolate the VT which is still connected from secondary side.?
1 4118i am iti student i have project to do. that IS 100MW 220\33KV SUBSTATION I WANT TO KNOW HOW TO START, LIKE CALCULATION, WHAT RATING OF CT,CVT, PT, ISOLATOR LIGHTING ARRESTER WAVE TRAP CIRCUIT BREAKER IN 22OKV SIDE, ALSO TO WARDS 33KV SIDE PLS HELP ME WITH THIS, THIS MY LIFE NOW, I KNOW AUTOCAD, I LIKE TO KNOW HOW TO CALCULATE ALL THE THINGS
