An electrical apparatus for electrical energy handling includes 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 includes an organofluorine compound and at least one further gaseous component. The apparatus further includes 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 includes 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.
