An electrical apparatus for electrical energy handling comprises a housing with at least one insulation space, in which an electrical component is arranged and which contains an insulation medium surrounding the electrical component. The insulation medium comprises an organofluorine compound and at least one further gaseous component. Apparatus further comprises a gas flow generating device for flowing an initial gas mixture, containing the organofluorine compound and at least one further component of the insulation medium, out of the insulation space through an outlet opening arranged in the housing. A substance recovery device downstream of outlet opening comprises a separator for separating the organofluorine compound from the at least one further component of the initial gas mixture, the separator being a liquefaction device for liquefying and/or solidification device for solidifying the organofluorine compound.
