Abstract: A system for detecting a partial discharge in electric power equipment is disclosed. The has a sensor located so as to receive ultra-high frequency signals related to the partial discharge, which has antenna and two or more envelope detectors connected to the antenna through respective bandpass filters. A measurement hub is located so as to allow safe access and has a computational platform. The sensor and the measurement hub are interconnected by a cable. The antenna derives UHF signals in different frequency bands, and envelope detectors simultaneously detect respective baseband signals from the UHF signals. Cable transmits the baseband signals on corresponding signal lines of the cable from the sensor to the measurement hub. A corresponding method is also provided.

Abstract: Method and system for identifying sources of partial discharge (PD), from a set of potential sources, in an alternating current three-phase high-voltage power-distribution system are disclosed. A timing signal is generated, phase-locked to a selected phase of three phases of the power-distribution system, having a measurable phase displacement from the selected phase. A cyclical timer is generated for indicating time within a power cycle based on a master clock phase-locked to the timing signal. A power-cycle period is partitioned into a number of dual observation windows, each dual observation window corresponding to a potential source and having two individual windows, ?-radians apart, and a specified window width. From a PD-detection apparatus, using the timing signal and the timer, magnitudes and time instants of PD detection during successive power cycles are received. PD detection is associated with respective dual observation windows, hence respective PD sources based, on the time instants.

Abstract: A method for detecting a partial discharge in electric power equipment is disclosed. Two or more narrowband signals corresponding to respective frequency bands of the partial discharge are obtained by two or more receivers, and a temporal coincidence of the two or more narrowband signals is detected, thereby indicating a possible presence of the partial discharge. Then a synchronous recurrence of the partial discharge over a plurality of power cycles is determined, thereby validating the possible presence of the partial discharge. A corresponding system is also provided.
