Abstract: A power device includes a gas chamber adapted to include an insulation gas under a set of use conditions including a predetermined installation pressure, and an insulation component including a material in which said insulation gas is soluble and being arranged in relation to said gas chamber so as to be at least partly exposed to said insulation gas when the power device is in said use state. The power device has a delivery state, being a state of said power device before and/or at an installation time at which the power device is installed in said electric energy power arrangement under said set of use conditions including said installation pressure of said insulation gas in said gas chamber, wherein, in said delivery state, said insulation component includes an amount of pre-filled insulation gas which is dissolved in the material of the insulation component.

Abstract: An apparatus for heating an insulation fluid in a medium-voltage or high-voltage switchgear comprises an infrared source which is adapted to emit infrared radiation of at least one wavelength. Thus, at least one vibrational or rotational mode of at least one component of the insulation fluid is excited by absorption of at least a part of the infrared radiation, and condensation of the insulation fluid is efficiently prevented by this direct heating of the insulation fluid. A closed loop temperature regulator is used to heat only when required. A circulator in a heating chamber further provides for a mixing of the insulation fluid, thus preventing steep temperature gradients.

Abstract: An open surge arrester has an active part with a number of surge arrester elements of a metal oxide varistor material, arranged between two end fittings, and, a retaining part with a number of rods of an insulating material for mechanically holding the surge arrester together. Both the active part and the retaining part are exposed to the environment surrounding the surge arrester and are individually profiled to provide an extended creep distance between the end fittings.
