Question:
Three single phase transformers with three windings are connected as below for three-phase operation:
Winding #1: Star connected and grounded through an impedance of Zn = j0.05 pu
Winding #2: Star connected with star point solidly grounded
Winding #3: Delta connected the impedance of each winding is given to be (0.01 + j0.02) pu.
All impedance values are on a common system base SKETCH THE SEQUENCE EQUIVALENT NETWORK for the transformer.
