Abstract
Seiring berkembangnya perusahaan dari tahun ke tahun, pasti kebutuhan pelanggan semakin meningkat. Tidak menutup kemungkinan perusahaan tersebut akan menambahkan beban baru pada sistem kelistrikannya. Dalam kondisi tersebut maka perusahaan harus menyadari akan keandalan peralatan yang saat ini sedang digunakan untuk bekerja secara terus menerus dan meminimalisir akan terjadinya pemadaman yang akan menimbulkan kerugian materi yang cukup besar dan kerusakan peralatan. Maka dibutuhkan suatu perencanaan sistem tenaga listrik untuk beberapa tahun kedepan. Dalam melakukan koordinasi pengaman dibutuhkan pengaturan rele yang tepat, agar Pemutus tenaga membuka ketika rele merasakan adanya gangguan hubungan singkat. Dengan kondisi sistem kelistrikan eksisting PT. Smelting Gresik yang belum terkoordinasi dengan baik berdasarkan waktu jeda rele antar pengaman yang cukup cepat. Dengan dilakukan evaluasi pengaturan waktu tunda sesuai standar rele utama dan rele cadangan telah terkoordinasi dengan baik. Selain itu juga melakukan perhitungan insiden energi dan lama terjadinya Busur Api ketika Pemutus tenaga membuka jarak aman bagi teknisi menggunakan standar IEEE 1584-2002 dan NFPA 70E-2015. Berdasarkan hasil evaluasi, insiden energi mengalami sedikit kenaikan dengan selisih paling besar yaitu 10,92 cal/m2. Dikarenakan faktor waktu buka rele hingga pemutus tenaga terbuka kondisi eksisting yang lebih kecil daripada kondisi pengaturan ulang yang sudah terkoordinasi lebih baik. Untuk tugas akhir ini juga diperlukan perangkat lunak pendukung untuk simulasi yaitu ETAP 12.6.

As the company grows from year to year, surely customer needs are increasing. It does not rule out the possibility that the company will add a new burden to the electricity system. Under these conditions, the company must be aware of the reliability of equipment that is currently being used to work continuously and minimize the occurrence of blackouts that will cause substantial material losses and equipment damage. Then a power system planning is needed for the next few years. In protection coordination, the right relay setting is needed, so that the circuit breaker opens when the relay senses a short circuit. With the condition of electrical system of existing PT. Smelting Gresik which has not been coordinated well based on the lag time of the inter-secure rele. With the evaluation of time delay setting according to main relay standard and backup relay has been well coordinated. Based on the results of the evaluation, the energy incident experienced a slight increase with the greatest difference of 10.92 cal/m2. Due to the fault clearing time of existing condition that is smaller than the resetting condition that has been better coordinated. In addition it also calculates energy incidents and the duration of arcflash when a circuit breaker opens a safe distance for technicians using the IEEE 1584-2002 and NFPA 70E-2015 standard. For this final project, supporting software is also needed for simulation, namely ETAP 12.6.
