Abstract

A correlation of unsynchronized multi-end windows technique is used for locating partial discharge (PD) source on covered-conductor (CC) overhead lines. The maximum correlation factor between signal arrivals at two-end measuring points is used in order to find the ratio of correlation. Then the ratio of correlation signals is ploted against its ratio of difference distance. The graph is plotted using LAB Fit software. The algorithm is developed and tested by the means of simulation. Electromagnetic Transient Program-Alternating Transient Program (EMTP-ATP) is used to implement and analyze a PD monitoring system. The proposed algorithm performance is evaluated by extracting the high frequency features using windowed-standard deviation (STD). The simulated evaluation proves that an accurate PD source location can be achieved using the proposed algorithm technique.
