Patent number: 8729905Abstract: This invention relates to a method of detecting faults on an electrical power line (7) and a sensor (5) for use in such a method. Preferably, the sensor is a line-mounted sensor (5). The method comprises the initial step of determining an initial impedance profile for the power line (7), and thereafter the method comprises the subsequent steps of the line-mounted sensor (5) transmitting a conducted communication signal (41) along the power line, receiving a reflected signal (43) particular to the transmitted communication signal and correlating the transmitted signal and the reflected signal. By correlating the signals, it is possible to determine the actual impedance of the power line. The actual impedance of the power line may then be compared with the initial impedance profile and it is possible to ascertain whether a fault exists on the power line. Preferably, the method uses an adaptive filter to determine the location of the fault.Type: GrantFiled: May 22, 2007Date of Patent: May 20, 2014Assignee: General Electric CompanyInventors: Michael Anthony McCormack, Charles Brendan O'Sullivan

Publication number: 20110031977Abstract: This invention relates to a method and system for locating line faults in a medium voltage network (3). Heretofore, the known methods and systems provided relatively limited resolution of fault location. Typically, the fault location information was limited to a distance from the substation (5). In complex medium voltage networks with branching, these systems and methods are not ideal as faults could potentially be in a number of different locations, spread out over a large area. According to the present invention, line mounted sensors (23(a)-23(I) are positioned both upstream and downstream of each of the branch points (11 (a)-11 (e), 29(a)-29(b) and this enables a more accurate determination of the location of the fault in the medium voltage net-work. Furthermore, artificial neural networks are employed to improve detection and location of faults in the medium voltage net-work.Type: ApplicationFiled: April 16, 2009Publication date: February 10, 2011Inventors: Charles Brendan O'Sullivan, Michael Anthony McCormack
