OPEN-BOUNDARY FINITE-ELEMENT ANALYSIS OF IONIZED FIELD AROUND MONOPOLAR TRANSMISSION LINES

Abstract This paper presents a new iterative finite-element ballooning technique to solve Poisson's equation for different numbers of ballooning layers to set different boundaries of the ionized field around the transmission-line coronating conductor. This is aimed at explaining how the accuracy of calculation increases with the increase of the number of ballooning layers. A laboratory model was built to check the accuracy of the calculated corona current and the ground plane current density.
