Natural Contamination and Surface Flashover on Silicone Rubber Surface under Haze–Fog Environment

Anti-pollution flashover of insulator is important for power systems. In recent years, haze-fog weather occurs frequently, which makes discharge occurs easily on the insulator surface and accelerates insulation aging of insulator. In order to study the influence of haze-fog on the surface discharge of room temperature vulcanized silicone rubber, an artificial haze-fog lab was established. Based...

From Maxwell’s displacement current to superconducting current

We investigate the nature of the superconducting current from the Maxwell’s displacement current. We argue that the conduction current density term of the Maxwell’s equations is physically untrue, and it should be eliminated from the equations. Essentially, both the superconducting current and conduction current are originated from the Maxwell’s displacement current characterizing the changes o...

Analysis of Leakage Current to Predict Insulator Flashover Using Artificial Neural Network

Problem statement: The phenomenon of flashover in polluted insulators has been continued by the study of the characteristics of contaminating layers deposited on the surface of insulators in high voltage laboratories. In the literature, Experimental investigations have been carried out on a real insulator or a flat plate model of insulators under high voltage application. This study proposed th...
