Abstract

Indonesia is a country that located on the equator, which stretches across the nation. This geographical condition resulted in a high number of thunderstorms per year, leading to a significant incidence of lightning strikes. These strikes can disrupt the delivery of electricity and affect power systems. Therefore, a protective system is needed to anticipate these issues, specifically the use of the lightning arresters to protect equipment from lightning strikes. Lightning arresters are essential devices that safeguard electrical system equipment, such as transformers, from overvoltage disturbances caused by short circuits or lightning strikes. The goal of this study is to determine the optimum distance of lightning arresters to transformers as protection against lightning disturbance. The maximum calculated distance between lightning arrester and transformers is 10,96 m while the one installed at the Tengkawang substation is positioned 3,50 m away. This distance is still well below the maximum threshold, indicating that the closer the lightning arrester is to the equipment it protects, the better the protection, and the voltage that has reached the transformer is below than the basic insulation level of transformer that 650 kV the number of voltages that has reach the transformer is 501,75 kV.
