要約(日本語): Location of partial discharge source is a key issue for a diagnosis of electric power apparatus and facilities. The system of monitoring an entire substation is a cost-effective approach. Following this concept, we have developed the localization method for a partial discharge source. This paper presents further work with respect to multiple sources, which locates source positions based on the maximum a posteriori estimation. The capability of the proposed system was confirmed by simulations using the finite difference time domain method. The results include the comparison of performance for the number of sensors.
