Radiating signal model for broadband acoustic emission from high voltage equipment

This paper presents a radiating signal model that simulates the acoustic emission from high voltage equipment. This theoretical model was formulated for radiating signals originate from high voltage equipment such as transformer, insulator and gas-insulated chamber using the numerical method known as the finite-difference time-domain (FDTD) method. The FDTD method has been widely applied in the analysis of electromagnetic waves. Its applications range from the design of antennas to the study of radiation effects on the human body. A simple one source one receiver model was used to demonstrate the capability of the FDTD method. Using the FDTD method to study the theoretical aspects of high voltage acoustic emissions, researchers can better understand the properties and characteristics of the phenomena.
