Abstract
The electric protection system in overhead transmission network is the main requirement to protect electrical equipment from various potential hazards. With this protection system, the age of the electrical components in the network can be maintained. Overhead transmission network is vulnerable to various hazards, especially lightning strikes, so a protection system is needed. Lightning strikes can disrupt the distribution of air transmission currents. Therefore, air transmission lines generally have protective elements such as Over Head Ground Wire (OHGW), lightning arresters, and grounding. These parts will protect the overhead network from lightning strikes. Arrester components were installed every 250 meters, while Overhead Ground wire components were installed at 12.5 meters. Arrester and OHGW distance and height can be adjusted to optimize trolley wire protection. Based on observations, the components installed were in accordance with the nominal pressure. With this arrangement, the potential for damage to the parts contained in the air transmission line can be minimized.
