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. |
