Abstract
Arc Flash melepaskan energi yang dapat merusak peralatan dan membahayakan pekerja yang berada di lingkungan tersebut, karena dapat mengandung energi dengan radiasi panas mencapai 〖35.000〗^0F. Oleh karena dampak yang mungkin terjadi maka diperlukan batas aman bagi pekerja berdasarkan energi yang terjadi, analisis arc flash dapat menggunakan IEEE 1584-2002 maupun dengan metode modifikasi. Standar IEEE 1584-2002 menghitung insiden energi menggunakan bolted three-phase fault terbesar dan fault clearing time untuk mengamankan arus gangguan yang terjadi, sedangkan metode modifikasi menghitung berdasarkan mula kontribusi arus hubung singkat hingga waktu mengamankan gangguan (fault clearing time). Dari hasil perhitungan untuk analisis arc flash pada sistem kelistrikan 6 kV, nilai insiden energi arc flash menggunakan metode modifikasi memiliki nilai yang lebih rendah dibanding standar IEEE 1584-2002. Menggunakan standar IEEE 1584-2002 pada bus 10BBA01, 10BBB01, 10BCA01, dan 10BCB01 menghasilkan insiden energi secara berurutan sebesar 46,29 cal/〖cm〗^2, 43,65 cal/〖cm〗^2, 24,10 cal/〖cm〗^2 dan 22,88 cal/〖cm〗^2, sedangkan metode modifikasi menghasilkan insiden energi 38,73 cal/〖cm〗^2, 36,32 cal/〖cm〗^2, 20,54 cal/〖cm〗^2, 19,23 cal/〖cm〗^2. Selain itu pada rele differensial 87GTU terdapat kesalahan pemilihan pick up yang menyababkan rele bekerja saat terjadi gangguan eksternal 2 phase pada bus 10BAA. Hasil analisis didapatkan setting rele differensial adalah I_set=1,4Ie, I_(instan )=5,2Ie, dan slope=0,75.

Arc flash release energy can damage equipment and dangerous for the workers who working in the area, because it can contain energy with heat radiation reaching of 〖35.000〗^0F. Because of the impact that might occur, a flash protection boundary is needed for the workers based on the energy that occurs, arc flash analysis can use IEEE 1584-2002 or by modification methods. The IEEE 1584-2002 standard calculates energy incidents using the largest bolted three-phase fault and fault clearing time to secure the occurrence of fault currents, while the modification method calculates based on the contribution of short-circuit currents to fault clearing time. From the results of calculations for arc flash analysis on a 6 kV electrical system, the value of incident arc flash energy using the modified method has a lower value than the IEEE 1584-2002 standard. Using the IEEE 1584-2002 standard on bus 10BBA01, 10BBB01, 10BCA01, and 10BCB01 produce energy incidents in a sequence of 46,29 cal/〖cm〗^2, 43,65 cal/〖cm〗^2, 24,10 cal/〖cm〗^2 dan 22,88 cal/〖cm〗^2, while the modification method produced an energy incident of 38,73 cal/〖cm〗^2, 36,32 cal/〖cm〗^2, 20,54 cal/〖cm〗^2, 19,23 cal/〖cm〗^2. Furthermore, at 87 GTU differential relay, the pick-up is error that will cause relay to work when there is an external 2 phase short circuit on the 10BAA or PLN 500 kV bus. Based on the results of the analysis it is recommended that the differential relay setting would be I_set=1,4 Ie, I_(instan )=5,28Ie, and slope= 0,75.
