  • Earthing transformers - Hitachi ABB Power Grids

    2021-9-13u2002·u2002Earthing transformers. An earthing transformer is usually associated with three-phase supply systems. On a three-phase system, the neutral would be earthed either directly or through some limiting impedance resistance. When the neutral point is not available or does not exist with a delta secondary winding of the transformer, a neutral point ...
