Earth-transforming generally exists in a three-phase system without neutral and earth fault protection. Neutral earthing transformers are often provided with a Zigzag (interstar) winding which is used in neutral earthing transformers to obtain the needed zero phase impedance. To address the need for an auxiliary power source, an additional auxiliary winding might be offered using the traditional pressed steel radiators, ONAN/ONAF cooling. The range is according to the needs of the location and includes up to 33 KV systems.
