- The internal fault of the transformer is simulated by an applied fault inside both side CTs and the External fault is simulated by an applied fault outside

- Inrush current also can be simulated by switch the transformer on no load

- RMS value of current can be observed on both side of distribution transformer and CT design give current for relaying algorithm
