The Study on Locating Technology of Partial Discharge Fault for 110kV GIS
In order to study the location of GIS partial discharge using UHF method,the location system of partial discharge is developed.In the system the data is sampled by oscilloscope and the data processing and computing are completed by computer.The time difference which is calculated by the algorithm of cross correlation is used by the software as the location method.The partial discharge sources are placed in the different position of the GIS model.The result of the location experiment shows that the system can effectively detect the partial discharge signal and complete the fault location.The software and hardware design of the system is feasible.
