Abstract


PT. Semen Indonesia pabrik Aceh merupakan perusahaan patungan (joint venture company) antara PT. Semen Indonesia (Persero) bersama PT. Samana Citra Agung. Total daya listrik yang dibutuhkan sebesar 85.8 MW dengan sistem kelistrikan pada sistem tegangan rendah dan menengah. Guna menjaga kontinuitas daya listrik, diperlukan koordinasi proteksi untuk meminimalisir dampak yang ditimbulkan ketika terjadi gangguan. Salah satu dampak yang ditimbulkan adalah adanya busur api (arc flash). Namun demikian, energi yang dihasilkan oleh busur api setelah dilakukan koordinasi proteksi perlu dipertimbangkan agar tidak melampaui standard yang diizinkan. Analisa busur api dilakukan dengan menggunakan perhitungan standar IEEE 1584-2002. Setelah dilakukan beberapa analisa didapatkan bahwa beberapa daerah di PT. Semen Indonesia pabrik Aceh memiliki nilai insiden energi diatas kategori 4, sehingga diperlukan tambahan peralatan berupa rele differensial sebagai pengaman utama agar nilai insiden energi busur api bisa dikategorikan sesuai standard NFPA 70E.
