A software application for estimating corona inception field of typical overhead line conductors under variable atmospheric conditions

A software application for the estimation of the corona inception field and voltage of typical ACSR transmission line conductors is presented. The software, developed in Python, runs as an executable Microsoft Windows application. It calculates the inception field and voltage of line conductors, based on a physical model that considers the ionization processes involved in corona discharge as affected by atmospheric conditions and operating voltage polarity. With a user-friendly interface, the developed software is a useful tool for the design of overhead transmission lines allowing for the evaluation of corona activity, through parametric analysis.
