Abstract

This paper presents a simulation of locating noise source (Partial Discharge) on high-voltage apparatuses, by using antenna array that consisted of four monopole antennas as sensor to record the electromagnetic waves (EM) emitted from Partial Discharge (PD). The detection algorithm is based on the time difference of arrival (TDOA) of the signals received between antennas (by using one of four antennas as reference antenna). The methods to determine TDOAs are Akaike Information Criterion method, Energy Criterion method, Gabor Centroid method, threshold detection method, peak detection method, and/or cross-correlation method. These system use Y-shaped array configuration. The adjusted distance between antennas are 2 meter and 4 meter. From the observation and analysis results, Y-shaped array antenna configuration has accuracy 97.76%. The best method to get TDOA is the cross-correlation method.
