Abstract

Dalam suatu sistem distribusi tenaga listrik sering terjadi adanya gangguan. Salah satu gangguan yang biasa terjadi pada sistem adalah gangguan hubung singkat. Gangguan hubung singkat dapat disebabkan oleh gangguan antar fasa maupun fasa ke tanah. Oleh karena itu, dibutuhkan setting relai yang baik untuk meminimalisir dampak gangguan. Pada penulisan ini penulis melakukan analisis gangguan pada sistem distribusi di feeder A01 MSS PT.Bukit Asam Tanjung Enim. Dari hasil perhitungan besarnya arus gangguan fasa ke fasa dan fasa ke tanah dengan berturut-turut pada feeder A01 yaitu 624,88 A dan 214,4 A. Kemudian hasil dari perhitungan pada setting relai OCR (Over Current Relay) dan GFR (Ground Fault Relay) berturut-turut adalah 675,024 A dan 25,68 A. Serta besar nilai waktu kerja relai (TMS) pada relai OCR dan GFR berturut-turut adalah 74 ms dan 160 ms. Dari perhitungan dan perbandingan nilai setting relai terdapat perbedaan antara hasil perhitungan dan data lapangan yang ada, hal ini terjadi karena adanya perbedaan ketelitian pada saat perhitungan dan kondisi yang dibutuhkan dilapangan.
