  • SYSTEM FOR ANALYZING AND LOCATING PARTIAL DISCHARGES
    Publication number: 20170336459
    Abstract: A sensor detects partial discharges (PDs) in an electrical power system and generates a corresponding analog electrical signal. A data acquisition component receives the signal from the sensor and converts it to digitized zero span data for a series of uniformly spaced frequencies in a frequency spectrum of interest. A digital signal processing component receives the digitized zero span data, analyzes such data, and generates a corresponding phase resolved spectrum signal in three dimensional format including dimensions of amplitude, phase and frequency for each of the uniformly spaced frequencies. A display component receives the analyzed data stream from the processing component and actuates one or more displays from which characteristics of the PD can be identified, such as different types of PDs from different sources, and information on the location of a PD relative to the sensor.
