Grounding Transformer

This device is a three-phase transformer. It generates an artificial loadable neutral point for neutral-less power systems to implement system grounding. In the event of a single-phase grounding fault, the system can maintain stable operation with a dedicated fault current path.
Available grounding configurations include direct grounding, as well as composite grounding matched with arc suppression coils, resistors or grounding reactors. The grounding transformer may be fitted with a continuous-duty secondary winding to act as station service power supply for substations.
It is applicable to 6 kV–35 kV medium-voltage distribution networks, power plants, substations, and collector lines & step-up substation systems of wind and photovoltaic power stations.
