Abstract

This paper presents an initial simulation study of the propagation of Partial discharge (PD) Acoustic Emission (AE) signals from high voltage equipment. The paper helps to investigate the propagation behaviour of the AE waves at the interface of two different media namely oil and steel. Reflection, refraction and scattering of the PD shock waves are simulated and displayed. The initial results show that the signals as expected can alter significantly based on the properties of the oil and the steel. The Partial Differential Equations (PDE) describing the signals have been solved using Finite Element Analysis (FEA). Through studying the theoretical aspects of PD AE signals, researchers and practitioners will better understand the properties and characteristic of PD experimental and practical high voltage equipment signatures e.g. power transformers.
