    Abstract: Pressure sensor for measurement of gas pressure in a cylinder of a combustion engine, including a tube shaped in cross section as an hourglass. In the axial direction the tube consists in part of a section connected to the cylinder and open to the cylinder, in part of a measuring section and in part of a final section the end of which is closed. The measuring section of the tube is shaped so that in the tubes axial direction two parallel measuring surfaces are established against which are two beams connected to force transferring yokes arranged to influence force measuring organs for the determination of the force with which the gas pressure influences the parallel measuring surfaces of the tube. In this pressure sensor and other embodiments the influences of temperature fluctuations and any shunting effects of the material of the measuring tube are reduced to a minimum.

    Abstract: A power transformer/inductor includes at least one winding. The winding is made of a high voltage cable that includes an electric conductor, and around the electric conductor is arranged a first semiconducting layer, around the first semiconducting layer is an insulating layer, and around the insulating layer is a second semiconducting layer. The second semiconducting layer is directly earthed at both ends of the winding and furthermore at least at two points per turn of every winding such that one or more points are indirectly earthed.

    Abstract: PCT No. PCT/SE97/00802 Sec. 371 Date Nov. 12, 1998 Sec. 102(e) Date Nov. 12, 1998 PCT Filed May 16, 1997 PCT Pub. No. WO97/44795 PCT Pub. Date Nov. 27, 1997A controllable inductor comprises at least a tubular core, a main winding (1) surrounding the core and a control winding (3) passing substantially axially through the core. It is adapted for connection to a three phase alternating current network and has for this sake for each phase (14-16) a main winding (1) for connection to the phase, a core and a control winding, and the control windings of the three phases are electrically connected in series to each other.

    Abstract: The magnetic circuit of a synchronous compensator plant is included in an electric machine which is directly connected to a high supply voltage of 20-800 kV, preferably higher than 36 kV. The electric machine is provided with solid insulation and its winding(s) is/are built up of a cable (6) intended for high voltage comprising one or more current-carrying conductors (31) with a number of strands (36) surrounded by at least one outer and one inner semiconducting layer (34, 32) and intermediate insulating layers (33). The plant is made as a mobile unit.
