A composite electrical insulator including an integrated optical fiber sensor.

摘要

Composite insulator (1) has central rod (2), separately formed disks (4) and metallic pylon/line terminations (3,3'). An optical fibre (5) traverses the insulator under the disks and through the terminations. One end of the fibre is connected to a transmitter/ receiver (7,8) and the other in the line termination (3') is made reflective. Electrical discharges in the insulator damage the optical fibre sheath and are detected by the transmitter/receiver An Independent claim is also included for: A method for managing the transmission capacity of an electrical overhead line by using an integral optical fibre and Bragg network to indicate insulator temperature
