Generation, transmission, and distribution are the main components of a modern electrical power system. Transmission plays a crucial role in delivering electricity from power generation sources to main substations and then distributing it to customers. Indonesia, a maritime continental country spanning the equator, experiences significant lightning activity. According to NASA's LIS data, the Tegalluar Traction Substation area has a high density of lightning strikes (16 flashes/km2/year). The Tegalluar Traction Substation is a critical supply point for the 27.5 kV Jakarta - Bandung High - Speed Train system, served by Substations Gede Bage and Ujung Berung. These substations are particularly vulnerable due to their proximity to areas with high lightning strike density. Tall structures, such as transmission towers, are most susceptible to lightning strikes. The supply from these two substations serves as the main source for the Tegalluar Traction Substation, which features a tall multicircuit tower, increasing its exposure to lightning strikes. This study evaluates the condition of the existing tower concerning tropical lightning disturbances and provides recommendations for a safe and cost-effective (techno-economic) protection system to mitigate the impact of lightning strikes. The research findings are expected to enhance the operational reliability of the Jakarta - Bandung High - Speed rain by addressing the threat of tropical lightning disturbances. © 2024 IEEE.
