    Abstract: A method and device for operating a fluid-insulated electrical apparatus (1) are disclosed. The insulation fluid (10) of the electrical apparatus (1) comprises at least two components (A, B). The method comprises the step of determining a physical state of the insulation fluid (10) by measuring at least three measurement variables (p, p, T) by means of sensors (30). The method further comprises the step of deriving trend variables indicative of changes over time for the measurement variables (e.g. ρ, p, T) and/or for characterizing variables (e.g. p/T, PA/PB, PA/T, PB/T). These characterizing variables (p/T, PA/PB, PA/T, PB/T) are derived from the measurement variables (ρ, p, T) by using a relating equation, such as an equation of state, and are also indicative of the physical state of the insulation fluid (10). By testing for specific patterns of the trend variables, an operating state (O, Fl, F2) of the electrical apparatus (1) is determined. The possible operating states (O, Fl, F2) correspond to specific and distinguishable non-fault and fault scenarios for the electrical apparatus (1). Thus, operating states can be distinguished and troubleshooting in case of a failure is simplified.

    Abstract: The invention relates to a method for deriving at least one operating parameter P of a fluid-insulated electrical apparatus (1), in particular of gas-insulated switchgear (1). The operating parameter P is dependent on a dielectric breakdown strength E
    bd of an insulation fluid (10) of the electrical apparatus (1). The insulation fluid (10) comprises at least three components X, Y, and Z that are assigned to at least a first and a second component group A and B such that at least one component group comprises at least two components. The component groups A and B differ in their weighted average values of the molecular masses of the components in the respective component groups. Then, at least one quantity which is indicative of the concentration c
    A of the first component group A and of the concentration c
    B of the second component group B is determined from the insulation fluid (10), e.g. by measuring one or more measurement variables (p, p, T, λ, η, c
    s ) by means of one or more sensors (30). The operating parameter P is then derived using the at least one quantity.
