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.

Current and voltage waveforms on the branches of each node of a power distribution network are sampled. The samples are converted to digital signals which are resolved into spectral components and processed to obtain the power (KVA) phasor at each frequency (harmonic component) of interest. The phase angles of the phasors describe the directions of movement, and thereby the locations of the sources, of the power harmonics in the network. A summary report is generated.

System and method for monitoring the condition of electricity conductor support systems, i.e. towers, in a power network distribution system employing a tower structure integrity sensor assemblage. The system allows for identifying particular portions of a structural system for maintenance attention. The tower sensors allow identification of structural failures of electricity transmission towers.
