Zero sequence networks for different 3-phase loads are shown below.
The zero sequence equivalent circuits of 3-phase transformers can be drawn by using the following general circuit.
Z is the zero sequence impedance of the windings of the transformer. These are two series and two shunt switches. One series and one shunt switches are for both sides separately.
The series switch of a particular side is closed if it is star grounded and the shunt switch is closed if that side is delta connected, otherwise they are left open.
Application:
In the given circuit diagram, both the shunt switches are closed. Therefore, both the primary and secondary are delta-connected.
