Zero Sequence Equivalent Circuit Diagram of a Single Phase Distribution Transformer

Zero Sequence Equivalent Circuit Diagram of a Single Phase Distribution Transformer

Zero Sequence Equivalent Circuit Diagram of a Single Phase Distribution Transformer

(OP)
Hello everyone,

May i ask if how to represent the zero sequence equivalent circuit diagram of a single phase distribution transformer which primary winding is connected to phase A to ground of a four-wire system (A,B,C,N) or wye-grounded system? And its secondary winding is connected to a single phase loads.

Are there any references to support this query?

Thanks,

GRAEE

As seen from the high side it is simply a 1LG fault with impedance. In this case it is the impedance of the transformer.
