Grid Transformer

Touch-safe self-supply from the medium-voltage grid

EPRO Gallspach GmbH has developed a compact sized, touch-safe transformer that enables a 230V supply in transfer sta­tions of wind, PV, or hybrid parks for example, to be easily implemented. The transformer is installed on the grid side and supplies the stations from the generated medium voltage with 230V.

The transformer is used wherever:

  • a supply from an nearby network is not possible.
  • there is no supply transformer available, or no connection point is provided.
  • only limited space is available, requiring a compact size and touch safety.
  • no additional cable transferring work can be carried out for the low-voltage supply.

 
2 transformers are available:
 
Type HVOTT 24/5 transforms 20 kV auf 230 V,
and Type HVOTT 36/5, 33 kV auf 230 V, with a power rating of 5 kVA
 
The type designation refers to the insulation level and the rated power. Other voltage and power on request.
