  • Neutral earthing transformers - Cressall

    For delta-connected 3-wire electrical systems with no star point, one solution to the absence of a neutral for connection to the earth or ground connection is to create an artificial neutral by using a zigzag or delta-star earthing transformer with a low voltage secondary winding. This can be connected to a suitably rated resistor of which the other terminal is earthed.
