Grounding Transformers three-phase electric power systems wind farms Skip to content


Grounding transformers are used to provide a ground path to either an ungrounded “Y” or delta connected system. 

Large multi-turbine wind farms often require Grounding transformers for fault protection on ungrounded lines. A Grounding transformer placed on the turbine string provides a ground path in the event the string becomes isolated from the system ground. 

Grounding transformers are typically constructed with either a Zig-Zag connected winding with or without an auxiliary winding or as a Wye connected winding with a Delta connected secondary.
