Instrument transformer VIE series

cast resinprotectionfor indoor service

Our production line includes single or double pole supporting type voltage transformers for indoor installation. They contain up to three windings for revenue metering and protection purposes. An extra 100/3 V winding can be provided in case the earth fault detection is demanded. Their cores are constructed from high quality siliceoussteel laminations. All active parts are altogether impregnated with cycloaliphatic outdoor resin. If an additional ratio is requested, thiscan be achieved by an intermediate terminal at the secondary coil or an additional coil. Each terminal of the secondary coil can be grounded individually directly to the metal base through a bolt. These types aremaintenance free,and with respect to their main dimensions many types correspond to the German standards DIN 42600.
