Abstract
Indonesia is a country with the highest lightning density in the world. Lightning strikes are the highest cause of failure in transmission lines which will interrupt the availability of electricity. PLN as an asset owner and manager of transmission lines wants to make sure the reliability of its assets from any disturbances. To minimize the impact of lightning strikes on the transmission lines, PLN utilizes data from the lightning detection system installed since 2017 to support the planning and operational processes. To improve the performance of transmission lines against lightning strikes, several mitigation options are implemented in the field such as installation of separated ground wire on towers, installation of transmission lightning arresters, and installation of active air terminals. Performance evaluation of each mitigation options is also presented in this paper.
