Calculation of Flashover Characteristics in the Electromagnetic Transients Program

This paper proposes arcing horn flashover models for a multi-phase flashover analysis and a lightning surge analysis by the ATP (EMTP). One is the leader development model which consists of nonlinear resistances. Another is the integration method which is not considered a predischarge current, but it is convenient to calculate. The calculated results by the proposed models agree well with experimental results. It is effective to simulate electrical power networks with various parameters (gap lengths, lightning currents, circuit models, and so on).
