Abstract

This paper has investigated a surge propagation characteristic of an 1, 100 kV transmission line based on field test results and EMTP simulations. It has been made clear by the EMTP simulations that the archorn voltage is almost the same as the phase-wire voltage to earth, and thus the measured archorn voltage can be regarded as the phase-to-earth voltage. Surge-wave deformation after a distance greater than 2 km measured in the field test is analytically explained due to separation of modal traveling waves, the earth-return and the aerial modes, for the traveling times of the two modes become noticeably different. A distinctive feature of the 1, 100 kV line is very small attenuation, about a half of that on a 500 kV transmission line.
