Estimation of Sparkover Rate of Medium-Voltage Line Due to Indirect Lightning Hit Taking account of Statistics on Return-stroke Current

Year: 2006

Type: article

Abstract: The authors have developed a method of analysis of induced voltages where the Agrawal's model is adopted as a field-to-line coupling model. In this letter, the sparkover rate of a power distribution line associated with indirect hits is investigated based on numerical calculations taking account of statistics on return-stroke current. It turns out that the sparkover rate associated with a subsequent stroke is higher than that associated with a first stroke when the line is equipped with surge arresters.
