ETR — grounding (neutral-forming) transformers 6–52 kV
ETR grounding (neutral-forming) transformers for 6–52 kV networks with a rating of 200–8000 kVA. They create an artificial neutral in distribution networks, to which arc-suppression reactors or resistors are connected.

Description
The transformers are built for network voltages of 6, 10, 15, 20, 35 and 52 kV. The vector group is ZN, ZNyn11 or another on request. The tank is hermetically sealed or has an oil conservator. Such a transformer is installed where the neutral of the power transformers is not available for connecting a reactor or resistor.
