Abstract: The present invention relates to a method for diagnosing, monitoring and/or predicting a condition of a switching apparatus, the switching apparatus containing an insulation medium comprising at least one organofluorine compound C1, said method comprising the steps of : a) selecting at least one physical quantity x of the insulation medium; b) determining the difference between value x
so of the physical quantity x at initial state S0 of the apparatus and value x
S1 of the physical quantity x at second state S1, with SI being later in time than S0, and c) deducing from the difference between x
so and x
S1 the decrease in amount of the organofluorine compound C1 and/or the total amount of the organofluorine compound C1, wherein the physical quantity x is the amount of a decomposition product C2 of the organofluorine compound CI or a physical quantity dependent thereon.

Abstract: The present invention relates to an electrical apparatus having an insulating space which contains a dielectric insulation fluid comprising an organofluorine compound. At least one solid component of the apparatus that is directly exposed to the insulation fluid contains a basic body made of a first material and a protective layer made of a second material different from the first material, the protective layer being directly or indirectly applied on the basic body and having a thickness of at least 50 μm. The organofluorine compound is selected from the group consisting of: fluoroethers, fluoroketones, fluoroolefins, fluoronitriles, and mixtures thereof, and the first material comprises or consists of a material selected from the group consisting of: a polymeric material, a ceramic, a composite material, and mixtures or combinations thereof.

Abstract: The present invention relates to an electrical device (1) comprising a gas-insulated transformer (101) or reactor. The electrical device (1) comprises a housing (12) enclosing an interior space (14), at least a portion of which defining an insulation space (16) containing a dielectric insulation fluid comprising an organofluorine compound, and an electrical component (18) being arranged in the insulation space (16) and being surrounded by the insulation fluid. The electrical component (18) comprises at least one winding (20, 22). The electrical device (1) further comprises an electrical connector (32) for bringing the apparatus (10) from non- operational state to operational state by connecting at least one winding (20, 22) to a power grid. The device (1) further comprises an auxiliary power source (34) which is connectable to at least one winding (20, 22) when the apparatus (10) is in the non-operational state.
