siemens sf6 o2 device for transformers

platform for an earthing transformer, the earthing unit is built directly within the same tank as the transformer's active part. This saves additional weight by omitting an extra tank for the device. The earthing transformer is built in together with the active part and assembled and tested in the same transformer factory as the main unit.

  • First SF6-free voltage transformers - Siemens Energy Global

    Until now, SF 6-free voltage transformers were available for voltages up to 245 kV. Recently, Siemens has succeeded to expand the blue portfolio, which exists of a broad spectrum of CO 2 equivalent-free equipment for air-insulated and gas-insulated switchgear, with a 420 kV voltage transformer. Hereby blue products enter the highest available voltage range in Germany of 420 kV.

  • mobile SF6 GDM | References | Siemens Energy Global

    As SF6 is an insulation gas with excellent electrical characteristics, it is possible to distribute and transmit energy with highest electrical safety. If pressure rises inside a compartment, as a result of an internal fault or lightning, the monitor detects this fast-rising pressure and instantly communicated with the control and protection system to reestablish a fault-free operational condition.
