Abstract
This paper presents a three-dimensional (3D) localization system for locating partial discharge (PD) on high-voltage apparatuses. An antenna array consisted of four sensors is employed to record the electromagnetic waves (EM) emitted from PD. The localization algorithm is based on the time difference of arrival (TDOA) of the signals. The TDOAs can be determined using the cross-correlation method, peak detection method, Akaike Information Criterion (AIC) method, Energy Criterion (EC) method, Gabor Centroid method, and/or threshold detection method. These system use two kind of antenna configurations. The first configuration is squared array with distance between antennas are 2 meter, and the second configuration is squared array with distance between antennas are 4 meter. In experimental setup, the implemented configuration is the first configuration, due to limitation of the experiment area. The effectiveness of the location method is tested through a computer simulation and the results are presented. From simulation result, the second configuration gives 11.12% better accuracy than the first configuration.
