transformer?
Answer Posted / santosh
Always HT volts are the out put of a EHV transformer which is Delta-Delta connection.But in general Distribution transformer,We have HT(11kv) primary side and LT(415v) secondary side. So 11kv should be Connected with delta connection and 415v should have star connection.
Mainly LV/2ndary side connected to home appliances,which is running with 1-phase and 1-neutral.
