ABSTRACT:
A resistivity sensor system for use with sealed, gas-insulated electrical apparatus. The system includes a resistivity sensor for placement within a housing of the electrical apparatus. The sensor itself includes an electrically insulating substrate, a pair of spaced-apart electrodes located on the substrate, and a polymer film in the space between the electrodes. The electrical resistivity across the polymer film changing significantly with the occurrence of a fault within the vicinity of the sensor, as the fault causes a reaction at the polymer film. To detect the location of the fault, a voltage is applied across the electrodes, and the current flowing through the electrodes is measured.
