要約(英語): Lightning surge analysis is very important for rational lightning protection design of distribution line. In order to establish a calculation method of a power distribution line flashover ratio due to lightning, it is important to estimate flashover behavior of a distribution insulator accurately. Insulator voltage waveform, which appears across an insulator on distribution line by a lightning stroke, tends to very short wave tail. However, flashover phenomena of the distribution insulator with the short wave tail lightning impulse voltage waveform and its modeling methods are not clarified.This paper proposes a distribution insulator flashover model for lightning surge analysis. At first, we clarify the flashover characteristics of a distribution insulator with a short wave tail lightning impulse voltage waveform. Then, we propose the flashover model based on the integration method. The proposed model consists of simple two equations, and can be realized very easily on transient analysis programs. A comparison of results calculated by the proposed model with the experimental results shows good agreements.
