In 1000KVA Transformer why does we connect HT with delta
connection and LT with star connection.Illustrate by showing
formula?
Answer Posted / guest
Stepdown transformer(HT/LT) generaly used for distribution purpose so secondary side star is necessary and to increase voltage ratio primary side delta is necessary ie. in delta we get line voltage which is 1.732 time of phase voltage (star voltag) therefore less turn required in secondary side.
