Resumo:
In this work, we develop a method for locating partial discharges (PDs), in power transformers, based on GPS (Global Positioning System) algorithm. For analyzing the structure, we implement a software in which the di erential equations that describe the propagation of acoustic waves are solved numerically by the Acoustic Finite-Di erence Time-Domain (AFDTD) method. The AFDTD computational domain is truncated by the CPML technique (Convolutional Perfectly Matched Layer). The obtained results are compared to estimates produced using electromagnetic waves generated by PDs.
