Maintenance of 20 kV SUTM Distribution Network System (ROSE Feeder) at PT. PLN ULP Krian

Distribution channel power distribution is usually called 20 KV Medium Voltage Overhead Line (SUTM). The main problem that frequently experiences disruptions in the distribution network's function is overcoming disturbances quickly and precisely. The most frequent disturbances experienced in the electric power system are in the distribution network, such as disturbances due to lightning, wind, rain, animals and damage. This research aims to determine the disturbances in the 20 kV distribution network and how to maintain the 20 kV SUTM distribution network system at PT. PLN (Persero) ULP Krian which is currently being carried out. This research applies a method of carrying out preventive maintenance or what is known as ROW (Right Of Way) maintenance to increase the effectiveness of the 20 kV distribution network. The research results showed that the disturbances that occurred were caused by internal factors such as disturbances in the SUTM channel and external factors caused by natural disasters, animals and kites. Preventive maintenance or ROW (Right Of Way) maintenance is implemented as an effort to increase the effectiveness of the distribution network, such as cutting down tree branches that have touched the network, straightening slanted poles, cleaning broken wires, replacing lightning arresters, and replacing broken pins. Highlights: Swift disruption resolution: Prompt response is vital for network reliability. Internal and external factors: Disturbances arise from channel issues and external elements. Preventive maintenance: ROW approach enhances network efficiency, tackling various issues. Keywords: Distribution Network Disruption, ROW Maintenance, Medium Voltage Air Line Maintenance
