Abstract: A hand-held system and method for detecting impaired electric power equipment. An exemplary embodiment may receive electromagnetic radiation and process the resulting signal. For example, signal processing may be used to identify electromagnetic radiation having a particular pattern that is characteristic of electric power equipment. Furthermore, an embodiment may determine the time and/or location during testing. As a result, an exemplary embodiment may be useful for stationary and/or mobile testing of an electrical system.

Abstract: System and method for detecting partial discharge arcing phenomena in a power network distribution system which employs a mobile receiving assemblage including a wideband antenna, a computer controllable wideband radio receiver deriving an amplitude detected output and a global positioning system providing system position data. The amplitude detected outputs are digitized and treated with a digital signal processor based analysis including fast Fourier transforms extracting narrowband signal frequencies that are harmonically related to the network fundamental frequency. The narrowband signal frequencies are analyzed for peak amplitudes which are summed to derive maintenance merit values related to the arcing phenomena.
