Differential Protection is intended to protect the
transformer windings. For this purpose we need to arrange
the CTs on both primary and secondary side of the
transformer and connect both the secondaries in such a way
that whenever the fault level increases above the threshold
value then the the associted relay will trip the power
circuit.

we all know that corona is nothing but ionization of air around the conductor and there by allowing current to pass through ionized air.but we are not getting any short circuit in between the respective phases though the air turned as a conductive media between them??
