Abstract: PROBLEM TO BE SOLVED: To provide a supporting insulator of a gas-insulated switchgear which is constructed so as to make a discharge path between the inner conductor (2) and capsule (3) of the switchgear have a partial section having a direction opposite to a bridging direction. SOLUTION: Surfaces (41 and 51) of a supporting insulator (4) have recessed parts (4b) having openings having concave shapes facing a component (2) or a supporter (3) in a region between the component (2) and the supporter (3).

Abstract: PROBLEM TO BE SOLVED: To provide a disconnector which has a high dielectric strength, and can be simply and inexpensively manufactured in small size. SOLUTION: The disconnector provides two insulated contacts (2) disposed in a conductive capsule container (1) filled with essentially insulating gas, and an insulated finger (3) movable between the insulated contacts. An insulating coating (7) is formed in the capsule container and has a protrusion (8) protruding toward the inner. The insulating coating prevents a spark generated in the disconnector from flashing over the capsule container (1) when the disconnector is opened. Another protrusion (9) prevents the spark from propagating toward the insulated contacts (2).

Abstract: A method and device for determining the linear response of an electrical multi-port component (1) has an "estimation procedure" in which an estimated admittance matrix is determined by applying voltages to the ports of the component and measuring the response of the component. The estimation procedure can e.g. consist of a conventional measurement of the admittance matrix. The method further has a "measurement procedure" in which several voltage patterns are applied to the port. The voltage patterns correspond to the eigenvectors of the estimated admittance matrix. For each applied voltage pattern, the response of the component is measured. This allows to measure the linear response of the component accurately even if the eigenvalues of the admittance matrix differ by several orders of magnitude.

Abstract: The supporting insulator has an insulating body (3) and at least one protective body (6) at least partly forming the surface of the insulator. The protective body contains a material with a lower dielectric constant than the material of the insulating body and/or has a structure with a lower mean dielectric constant than the material of the insulating body.

Abstract: The disconnector essentially comprises two isolating contacts (2), which are arranged in electrically conductive encapsulation (1) filled with insulating gas, and an isolating contact finger (3) arranged such that it can be moved between them. An insulation coating (7) is applied to the inside of the encapsulation (1) and has projections (8) pointing inward.The insulation coating prevents a disconnector spark (5), whose production cannot be avoided when the disconnector is opened, from flashing over onto the encapsulation (1). Furthermore, additional projections (9) prevent the spark from propagating in the direction of the isolating contacts (2).
