Dear all
i am working on the theory of isolation transformer . i was wondering if i have a transformer 11/0.415 KV that is Dyn11 connected. now if i want to connect as iisolation transformer on the .415KV side. so that i input the isolation transformer with .415KV and then get at the output again .415Kv. what i wanted to ask was. my .415KV in Star connected. so i will have a neutral wire too. what will be the connections of my isolation transformer? will i input it in delta or star? if i input in the delta what will happen to the neutral wire.? your help would be highly appreciated..
