description: The topic of this graduate qualification paper is âCorona inception modeling on overhead line conductorsâ. The paper study the corona inception parameters such as electric field and voltage. The authors try to find a universal engineering method for calculating the corona inception parameters of many electrodes configurations. This paper uses the FreeFem++ program as a typical finite element method program. The authors analyze three typical calculating way of the corona inception parameters: empiric formulas' method and Townsend equation method and kinetic equations' method. From these methods the authors select the Townsend equation method as the most suitable for engineering practice. For this choice's approve the authors create the Townsend equation model for the well-known electrodes' configuration. This model can use for calculating the corona inception parameters on an overhead line's conductors. As a result, the authors discover strongly depends this engineering method on the Townsend coefficients' quality which are determined experimentally. So this method describes experimental data well only in few cases. Also, the authors give another reason of the difference between theory and experiment: few quantities and low quality of unipolar corona inception experimental data.
