Abstract:
1. A sensor assembly for determining the concentration of hydrogen in an insulating fluid in electric power generation, transmission, and distribution equipment comprising: (a) a housing having an opening therein communicating with the fluid; (b) a hydrogen sensor disposed in the housing and responsive to the concentration of hydrogen in the fluid and generating a signal related to the concentration of hydrogen; (c) a pressure sensor disposed in the housing responsive to the fluid and generating a second signal indicative of the pressure of the fluid in the equipment; and; (d) a signal processor disposed in the housing and connected to the hydrogen sensor and the pressure sensor and responsive to the first and second signals for generating a third signal representing the concentration of hydrogen in the fluid, wherein the housing comprises a flange having a first threaded opening therethrough, a tube threaded into the opening, and in which the hydrogen sensor is disposed in the tube.
