Abstract


Upaya terakhir untuk menghitung bahaya yang berhubungan dengan potensi bahaya arc flash bergantung pada proteksi arus lebih untuk menghilangkan kondisi saat diberi gangguan. Efektivitas berbagai perangkat ditentukan oleh clearing time terkait dengan gangguan arus maksimum yang ada untuk setiap lokasi sistem. Industri komersial mulai melakukan prosedur pelabelan arc flash dan mulai mengenali pencegahan arc flash sebagai bagian dari program safety, perhitungan current method memungkinkan untuk menghitung incident energy (cal/cm² ) terkait dengan gangguan maksimum tiga phasa. Kesalahan terbanyak adalah besaran arus kurang dari besaran arus tiga phasa maksimum. Dalam Tugas Akhir ini akan dibahas perhitungan energy dan durasi lama terjadinya arc flash pada system kelistrikan pada electrical room.
