- Neutral earthing transformers are normally provided in 3-phase system, which is without neutral and earth fault protection.
- Neutral earthing transformer is having zig-zag (interstar) winding to achieve the required zero phase impedance.Â
- In addition an auxiliary winding can also be provided to meet the requirement of auxiliary power supply in these electrical earthing transformers.
