In power system distribution sector is very important section as per protection purpose. Because maximum faults are occurred at distribution level because human mistake as well as environmental condition. Protection of Distribution transformers is very important role in power system. The distribution networks throughout the world of modern power systems. In this invention, the fault-current-limiting capability is enabled in power transformers by accepting the theory of virtual-air-gap (VAG) in electromagnetics. The concept of VAG is nothing but the saturate a certain portion of the magnetic core to change the reluctance of magnetic loops. VAG is not an actual air gap but a saturated portion of the magnetic core, which restricts the magnetic flux to follow through it. In distribution transformers, electric power is transferred between electric windings through the magnetic core interface. By changing the dc current, the redistribution of magnetic flux and isolation between the electric windings can be achieved. The power rating of the power electronics drive in VAG can be much smaller than the power rating of power transformers, which would greatly reduce the cost of device. __
