摘要
Analysis of transmission lines backflashovers is of particular importance for the service quality. The tower surge impedance is a key parameter for the prediction and estimation of backflashovers. In this paper we introduce a new multi-region soil model to take into account soil model variations along a transmission line while using a global full-wave modelling approach. This new capability focuses on the transient behavior of the whole system to assess backflashover occurrences along the transmission line.
