| Summary: | This paper presents a comparative lightning performance study conducted on the
275kY and 132 kV transmission line from Kimanis and SPR Power Stations to PMU
kolopis and PMU Lok Kawi, Sabah in quadruple circuit shielded transmission line
using a software programs, TFlash. The line performance was investigated by using
both a single stroke and a statistical performance analysis and considering cases of
shielding failure and backflashover. A sensitivity analysis was carried out to
determine the relationship between the flashover rate and the parameters influencing
it. To improve the lightning performance of the line, transmission line surge arresters
were introduced using different phase and line locations. Optimised arrester
affangements are proposed |
