Earthing Transformers & Reactors

Earthing transformers

A return path for earth current is needed to protect a system against earth fault currents. Earthing transformers, sometimes also called neutral couplers or grounding transformers, are used to create an artificial neutral point in a three phase system, which provides possibility for neutral earthing.

Our earthing transformers are naturally cooled and of hermetically sealed design with corrugated tank. The insulating liquid is inhibited mineral oil. Standard surface treatment according to C3 (ISO 12944).

The transformers are easy to install thanks to plug-in bushings and auxiliary wiring box for connection of signal cables. For personal safety are the low voltage bushings of auxiliary winding additionally equipped with protective covers.

Our design is flexible and we are able to design according to specific requirements on for instance zero sequence impedance or short circuit impedance if required.
