A Simulation Study of Performances for Different Substrates Sizes and Copper Thickness For PD Antenna Design

Abstract

Partial discharge (PD) is a phenomenon that consistently happens throughout the millennium in the power equipment. This phenomenon has an unpredictable and intermittent characteristic that hard to be detected easily. There are various available methods to detect this phenomenon, but each technique has its own flaws and drawback. This paper explored the early step to select, design, and simulate a PD UHF antenna for power transformer through CST MWS simulation. This task is crucial to choose the optimized substrate size and copper thickness for the PD antenna design. Based on the detailed analysis, it is substantially proven that there is an important relationship between substrate size towards antenna performance and characteristics to design an improved and efficient PD antenna.
