Theoretical Study of the Electrical Corona on a Long Wire.

Abstract

This report contains a theoretical study of the electrical corona on a long wire. The physics of the phenomenon is discussed in detail, and formulated mathematically in terms of coupled nonlinear partial differential equations. A number of boundary-value problems for these equations are solved to predict the corona breakdown field and the d-c corona voltage-current characteristic. The results are in good agreement with experiment. Finally, the d-c corona effect on large signal propagation along a single wire above ground is examined by solving a nonlinear transmission line equation. The purpose of this study is to identify the set of basic corona equations as well as the mathematical nature of the problem. The application of these equations to analyze the corona effect on aircraft long-wire antennas will entail the solution of certain time-dependent problems of considerable mathematical complexity. These latter problems are not covered in the present study, and should form the subject of future investigations. (Author)
