Abstract

Pada studi ini, penulis menguji kinerja dari surge arrester pada saluran distribusi tegangan menengah 20 kV terhadap sambaran petir berulang sebanyak tiga kali sambaran. Penguji melakukan tes untuk melihat tingkat keberhasilan surge arrester terhadap tingkat keberhasilan surge arrester ketika tiga petir melakukan sambaran dengan jarak waktu antar petir dipersingkat dan amplitude petir yang ditingkatkan. Pada penelitian ini dibuat model dan dilakukan simulasi pada saluran distribusi tegangan menengah yang tersambar petir menggunakan software ATPDraw. Pada simulasi ini digunakan variabel Tstart dan Amplitudo petir berulang yang berbeda untuk mengetes kinerja surge arrester. Variasi yang digunakan adalah Tstart sebesar (0 s, 0,06 s, 0,12 s) dan (0 s, 0,03 s, 0,09 s) dan untuk amplitude nya digunakan sebesar (16.000 A, 10.000 A, 10.000 A) dan (20.000 A, 14.000 A, 10.000 A). Hasil dari simulasi ini adalah ketika menggunakan surge arrester, tegangan yang masuk kedalam beban-beban sistem distribusi tegangan menegah lebih kecil dibandingkan tegangan ketika tidak menggunakan surge arrester. Terpotongnya tegangan listrik bisa sampai 50.000 kV sampai 80.000 kV dari tegangan asli yang masuk ketika tanpa menggunakan surge arrester.

In this study, the authors tested the performance of a surge arrester on a 20 kV medium voltage distribution line against three repeated lightning strikes. The tester conducted a test to see the success rate of the surge arrester against the success rate of the surge arrester when three lightning strikes with the time interval between lightning shortened and the lightning amplitude increased. In this study, a model was created and a simulation was carried out on a medium voltage distribution line that was struck by lightning using the ATP-Draw software. In this simulation, the variable Tstart and amplitude of repeated lightning are used to test the performance of the surge arrester. The variations used are Tstart of (0 s, 0.06 s, 0.12 s) and (0 s, 0.03 s, 0.09 s) and for the amplitudes used are (16,000 A, 10,000 A, 10,000 A ) and (20,000 A, 14,000 A, 10,000 A). The result of this simulation is when using a surge arrester, the voltage that goes into the loads of the medium voltage distribution system is smaller than the voltage when not using a surge arrester. The cut off of the mains voltage can be up to 50,000 kV to 80,000 kV from the original incoming voltage without using a surge arrester
