Optical waveguide arrangement for a high-voltage insulator

Abstract From the Canadian patent

In a high-voltage-conducting assembly (10) such as, for, example, the current transducer arrangement for a highvoltage outdoor installation, measurement information items are transmitted via optical waveguides from high-voltage potential to ground potential. To reduce the voltage gradient along the optical waveguide, the latter is spirally conducted along an optical waveguide carrier (7) between the high-voltage side (9) and the ground potential side (5) of a high-voltage insulator (6). The optical waveguide support (7) can be a self-supporting plastic coil (7) or the outer layer of the insulator tube of fibre-glass-reinforced plastic of the high-voltage insulator (6) or its silicon layer …
