Localization of partial discharge source in power transformer using bat algorithm

Abstract

Partial discharge (PD) source location in power transformer by measured acoustic signals using bat algorithm is presented. The available literature data considered for this case study is five sensors but for identification of PD source location needs not more than four sensors. Thus, five combinations results are analyzed using bat algorithm. This algorithm is tested on the measured acoustic TDOA signals which were reported in the literature. The results shows that bat algorithm enhances the search operation and there by PD location accuracy is better with other population based methods existing in the literature.
