	You have asked an incomplete question. What is the system voltage, what is the Transformer Apparant power rating? After you have established these points then we will discuss the SC (fault current) level and System current. Also that once all details have been provided which also include Transformer HT and LT terminal connections. Then we can advise you about some protection scheme.
