Study of EM Wave Propagation for Transformer PD Monitoring Using FDTD Method

Abstract:

Ultra high frequency (UHF) partial discharge (PD) detection technique is drawing attention to transformer insulation accident prevention. However, the configuration of a large oil-immersed transformer is very complicated, so the reflection, refraction and absorption phenomena between PD sources and UHF sensors need to be considered. The phenomena make it difficult to calibrate the magnitude and locate the source of a PD activity. Therefore, detailed investigation of EM wave propagation inside the tank is carried out to enhance the performance of UHF method. Numerical simulations are performed on the 3D models using finite difference time domain (FDTD) method. From the results, the effects of transformer oil, cores and the tanks are clarified.
