Analysis of Transmission Lightning Arrester Locations Using Tflash
Abstract: Tropical countries
with extensive lightning activity, such as Malaysia, encounter numerous problems
on their electrical transmission and distribution systems. Many overhead lines
trip because of back flashover of lightning and shielding failures of the
grounding system. To overcome the problem and improve transmission line
performance, a detailed lightning study is required to analyse the
corresponding lines and determine the best location for transmission line
arrester (TLA) installation. We used TFlash to analyse a TLA installation on a
132-kV SSWW-BBST overhead transmission line system located in Selangor,
Malaysia. Based on the results, the installation of the TLA at the optimum
quantity and at appropriate towers have reduced the number of lines that trip.
