Abstract: An electric network for generation and transmission of electric power has a power generating part (1), a point of common connection (PCC) for the power generating part, a transmission link (T, W, CAB), a load network (LN), and a reactive power compensating means (2, 2'). The transmission link is coupled between the point of common connection and a grid connection point (PGC) at the load network, and the reactive power compensating means is coupled to transmission link. The power generating part comprises at least one wind turbine (111) with an electric generator (113) of induction type, coupled to the point of common connection, and the reactive power compensating means comprises a capacitor bank (21) and in parallel coupling to said capacitor bank a controllable inductor (22). The inductor has a magnetic core (221), a main winding (222) for alternating current, and a DC-control winding (223) for direct current (Id), said DC-control winding for control of the magnetic flux set up by the main winding via orthogonal magnetization of the core.

Abstract: A device for quick closing of an electric high-voltage circuit. A main spark gap is provided with a first and a second main electrode, and a triggering device. The triggering device includes an auxiliary electrode gap provided with a first and a second auxiliary electrode and is adapted, where necessary, to generate an arc in the auxiliary spark gap for igniting an arc in the main spark gap. Each auxiliary electrode is provided with a guide rail designed such that the arc, via the guide rails and under the influence of the generated inherent magnetic field, moves into the main spark gap. The two guide rails each have a length that is larger than the width of the auxiliary spark gap. The auxiliary electrodes are adapted so as to be protected from the effect of plasma formed in the main spark gap. A hermetic enclosure encloses the main spark gap and the auxiliary spark gap.

The device comprises a spark gap (1), provided with a first (2) and a second (3) main electrode, and a triggering device (10). The triggering device comprises an auxiliary spark gap (4) provided with a first (5) and a second (6) auxiliary electrode and is adapted, where necessary, to generate an arc (a) in the auxiliary spark gap (4) to ignite an arc (A) in the main spark gap (1). According to the invention, each auxiliary electrode (5, 6) is provided with a guide rail (13, 14) designed such that the arc, via the guide rails and while being influenced by the generated magnetic field, moves into the main spark gap (1). The length of the guide rails is larger than the width of the auxiliary spark gap (4). The auxiliary electrodes (5, 6) are arranged such that they are protected from the effect of plasma formed in the main spark gap. The spark gaps are enclosed in a hermetic enclosure. The invention also relates to a method and a use.
