Abstract
The present invention relates to an electrical device comprising a gas-insulated transformer or reactor. The electrical device comprises a housing enclosing an interior space, at least a portion of which defining an insulation space containing a dielectric insulation fluid comprising an organofluorine compound, and an electrical component being arranged in the insulation space and being surrounded by the insulation fluid. The electrical component comprises at least one winding. The electrical device further comprises an electrical connector for bringing the apparatus from non-operational state to operational state by connecting at least one winding to a power grid. The device further comprises an auxiliary power source which is connectable to at least one winding when the apparatus is in the non-operational state.
