  • Electrostatic shield for an HVDC transmission component
    Patent number: 8520357
    Abstract: An electrostatic shield for an HVDC transmission component, the terminals of which lie at high potential relative to earth during operation, in particular for an HVDC transmission air-core coil, is distinguished by a sheathing, which is provided on at least one end with a collector electrode running substantially over its periphery for connection to one of the terminals of the HVDC transmission component, wherein the sheathing is made from a film composed of electrostatically dissipative material with a surface resistivity in the range of 109 to 1014 ohm/square.
    Type: Grant
    Filed: January 30, 2009
