Adaptive finite-element ballooning analysis of monopolar ionized field

الملخص EN

This paper presents an adaptive finite-element technique for the analysis of monopolar ionized field in conductor-to-plane configurations without resort to Deutsch’s assumption.

A new iterative-element ballooning technique is proposed to solve Poisson’s equation wherein the commonly used artificial boundary around the transmission line conductor is simulated at infinity.

The proposed technique seeks a solution to only one second-order partial differential equation (PDE) rather than a solution to a nonlinear third-order PDE or a solution to two simultaneous second order PDEs as reported in the literature.

The calculated corona current and the ground plane current-density agreed well with those measured experimentally for a laboratory model.

Accuracy and simplicity in programming characterize the proposed method.
