Modeling and Calculation of the Sharp Conductor Structure of Corona Discharge

In order to study the corona discharge on the sharp conductor structure, the relationship between conductor radius and corona was found by analysis of the three basic structures of corona discharge, and calculating the potential around the conductor in the three cases. Based on the three basic structures, the model of sharp conductor structure of corona discharge was established. Since of it, the threshold voltage of it could be easily calculated, which may provide supports for the further research on corona discharge on the sharp conductor structure.
