A study on Lightning Outages on the 150 kV Transmission Line of Payakumbuh-Koto Panjang in West Sumatra in Indonesia

Abstract: Lightning is a natural phenomenon that can cause a disturbance on a transmission line. From the data of the Distribution and Load Control Centre Sumatra (Sumatra P3B), the intensity of lightning trip-outs on a 150 kV transmission line was very high in Indonesia, reaching 66%. The results of the investigation showed correlations between the occurrence of trip-outs on a 150 kV transmission line and two factors, namely, the footing resistance of towers, and the span length of the towers.
