ABSTRACT:
An instrument system for monitoring corona and like conditions of electrical equipment such as generators includes an optical probe which receives light from a plurality of different areas in the equipment and separately conveys the light acquired from each area to a position-sensitive photoelectric converter. The probe includes optical fibers with terminal ends disposed in spaced holes in the wall of a tubular housing. The output of the photoelectric converter is analyzed to determine the presence of corona, arcing, flame ignition combustion, or smoldering conditions at each of the monitored areas in the equipment, the severity of such conditions, and the identity of materials involved in such conditions based on the intensity and spectral content of the acquired light. The photoelectric converter includes a photomultiplier, a photodiode array, and means for automatically directing the acquired light to either one in accordance with its intensity.
