Grounding Transofrmer Application:
The grounding transformer is used to provide a path to an
ungrounded system or when the
system neutral is not available for some reason, for example, when a system is delta connected.
It provides a low impedance path to the neutral and also limits the transient overvoltage when the
ground faults occur in the system. The grounding of the system can be done in the following
wayDelta-Star Grounding Transformer
In a case of delta-star grounding transformer, the delta side is closed to provide a path for zero-sequence current.
The star winding must be of the same voltage rating as the circuit that is to be grounded, whereas the delta voltage
rating can be chosen to be any standard voltage level.
