Answer Posted / infosys
neutral grounding transformers are used to derive a
neutral-to-earth connection for systems that do not
otherwise have one.
The grounding transformer can have a zigzag winding
arrangement, or a wye-delta arrangement.
The transformer primary terminals (wye side) are connected
to the power system, and its neutral is connected to earth,
perhaps through a controlled impedance. (Usually, with
Wye-delta grounding transformers, the impedance is connected
inside the delta.) No other load is connected to the delta
of the transformer.
These transformers provide a high impedance to normal
currents (positive & negative sequence), but allow ground
fault currents (zero sequence) to flow, thereby allowing
protective devices to operate if a ground fault occurs.
