Inspection of Wave Propagation Due to Partial Discharge Occurring in Current Transformer Using 3-D Finite Difference Time Domain Based Technique

R. M. Sharkawy and Tamer Adel Aziz

Abstract—This work aims to investigate the impact of a Partial Discharge (PD) pulse happening in the insulator conductor of a Current Transformer (CT) in a metallic tank filled with mineral oil. Finite Difference Time domain (FDTD, being an acceptable computation technique in the electromagnetic (EM) domain, is utilized for the simulation of the transient waves due to the PD pulse at different locations. The electric field intensity distribution at different planes is visualized. Analysis estimated both the optimal position of a sensor for PD detection and the dominant frequency enclosing the signals. Simulation run results are coded and recorded using Matlab. Observation of the PCOLOR outputs is discussed.

Index Terms—Current transformer (CT), electromagnetic (EM) waves, discharge (PD), finite difference time domain (FDTD), MATLAB
