What is a earthing transformer:

Grounding transformer or grounding transformer is an auxiliary transformer used in three-phase power system to provide grounding path for Ungrounded Wye or delta connected system. The grounding transformer is a part of the network grounding system. They allow three-phase (delta connected) systems to adapt to phase neutral loads by providing a return path of current to the neutral point.

Grounding transformers are generally used for:

Provide a relatively low impedance grounding line to keep the system neutral at or near the grounding potential

When a ground fault occurs again, the magnitude of transient overvoltage shall be limited.

Provide ground fault current source in case of line to ground fault.

Phase neutral load connections are allowed if required

Zigzag grounding transformer

The most common grounding transformer is a single winding transformer with a zigzag winding configuration, but you can also create a delta winding transformer. Neutral grounding transformer is very common on generators in power plants and wind farms. Neutral grounding transformer is sometimes used in high-voltage (secondary transmission) systems, such as 33 kV, otherwise the circuit will not be grounded; For example, if a system is powered by a delta connected transformer. The grounding point of the transformer can be connected through resistance or arc suppression coil to limit the fault current of the system in case of line to ground fault.
