Propagation Characteristics and Modeling of Traveling Lightning Surge Waveshapeson UHV Designed Transmission Line

Abstract

An experimental investigation was performed on a UHV long distance transmission line model for the EMTP calculation of lightning overvoltage at substation. The various lightning surge propagation characteristics were measured on an actual UHV transmission line.
In this paper, we present the traveling lightning surge waveshapes, propagation characteristics of peak voltage and front waveshapes and analyzed waveshapes by EMTP for insulation design of substation on UHV transmission line. In addition, we report on the relationships between peak voltage and propagation at 200km analyzed by EMTP.
