what is the safe meggar values for motor, transformer HT, LT and Cables? IF we want to replace I/C bay at our 220 kv substation which is of 140 mw load capacity bay to be replaced by 400 mw capacity bay.other than CT(1200/1) what are the other equipment i have to replace. why we generally use 3.5 core cable or in other word 1/2 core for neutral and also confirm me that in balance conditiob(3 phase)current in neutral will zero
