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: An electric machine comprises a core ( 10 ) of magnetic material and a first insulating layer ( 14 ) of a solid electrically insulating material surrounding the core. A high-voltage winding ( 17 ) in the form of an electric conductor is wound around a first part ( 16 ) of the first insulating layer and a field-equalizing member ( 19 ) is arranged around a second part ( 18 ) of the first insulation layer. Further, a second insulating layer ( 20 ) of a solid electrically insulating material surrounds the high-voltage winding and the field-equalizing member. The field-equalizing member comprises at least one first sub-member in the form of a winding ( 27, 28, 37, 38 ), and an electric cable conductor ( 31 ) is intended to be connected to the high-voltage winding at the field-equalizing member.

Abstract: The invention relates to an electric circuit breaker that includes at least one mobile contact. The contact is connected to operating means that includes an electric motor (6). Movement converting means (16, 17) are provided for converting rotary movement of the motor (6) to translatory movement for linear movment of the mobile contact. The object is to provide an improved movement conversion means. According to the invention, the movement conversion means includes a first body, such as a screw (17), and a second body, such as a nut (16). The threads of the screw (17) and the nut (16) co-act in engagement with each other. The invention also relates to an electric plant that is equipped with such a circuit breaker, to the use of the breaker for breaking electric current, and to a method of breaking electric current with the aid of the inventive circuit breaker.

Abstract: The present invention is related to an operating device (200) for driving and controlling the opening and closing of an electrical high voltage or medium voltage switching apparatus, such as a switch or a circuit breaker. The operating device comprises a rotating electric machine (201) which is operatively connected to a mobile contact (203) of the switching apparatus. The rotating electric machine (201) operates the mobile contact via a mechanical coupling (202) upon receiving control signals (208) from a control unit (205). The rotating electric machine (201) may, upon a decelerating motion of the mobile contact (203), transform the kinetic energy of the mobile contact (203) into electrical energy which can be transferred to a suitable energy storage or supply unit (204). The operating device according to the invention is especially suited to operate circuit breakers of all types.
