Investigation of lightning tripouts on 150‐kV transmission lines in West Sumatra in Indonesia

Abstract: Lightning activity in Indonesia is very high, and the ratio of lightning tripouts of the transmission line is also very high, reaching 66%. The results of our investigation show that a positive correlation exists between the number of lightning tripouts on a 150-kV transmission line and the tower-footing resistance and that the main cause of the tripouts is the back-flashover. Moreover, it turns out that the flashover at the lower arm increases in case of high tower-footing resistance.

“…Back-flashovers that occurred in the transmission line at rate of 74% were detected by the high value of the tower footing resistance. The high tower footing resistance value itself was influenced by the rock type in the transmission line and the location of the towers, 66% in hilly or mountainous areas [15]- [18].…”

“…Sistem transmisi tenaga listrik di Indonesia kususnya di Sumatera Barat yakni Payakumbuh-Koto Panjang didominasi menggunakan saluran udara dibandingkan dengan kabel bawah tanah (Warmi dan Michishita, 2016) (Warmi dan Ismail, 2018). Saluran udara cukup rentan terhadap sambaran petir karena konstruksinya yang tinggi (Warmi dan Ismail, 2018) (Warmi dan Michishita, 2015).…”

“…Pembahasan yang dilakukan adalah menentukan tegangan flashover isolator terhadap coating isolator dengan standar BIL. Menurut referensi (Warmi & Michishita, 2016), basic insulator level (BIL) untuk satu string isolator adalah 1,21 -1,27 MV. BIL bertujuan sebagai standar tegangan tembus isolator.…”
