Abstract:
Apparatus for monitoring the temperature of a high voltage conductor, which comprises:a) an electrically and thermally conductive fixture for attachment to a high voltage conductor, b) a high voltage insulator having a high voltage end and a reference potential end and a fiber optic cable passageway from the reference potential end to the high voltage end, said insulator being connected at said high voltage end to said fixture, c) a fiber optic cable within said passageway of said insulator, said cable extending beyond said insulator, d) an optical temperature sensor head optically coupled to said cable, said sensor head comprising a sensor crystal which transmits light that varies with temperature of the sensor crystal, e) an electrically and thermally conductive enclosure for said sensor head, supported in said fixture for thermally conductive contact with said high voltage conductor effective to couple the temperature of the high voltage conductor to said sensor crystal.
