Behavior of the corona current in coaxial systems with negative corona under controlled pressure conditions

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This paper studies the behavior of the corona effect in dry air and coaxial configuration for different pressure values. The study is conducted in a system of four parallel-connected coaxial cylinders placed inside a controlled pressure chamber. During the tests, DC current is measured through the coaxial system for various pressure values when a voltage, higher than the corona onset, is applied; then, a mathematical model that describes the behavior of the corona current as a function of pressure and applied voltage is obtained. The mathematical model accurately reproduces the behavior observed during the measurements.
