Abstract
Suatu sistem proteksi harus memiliki keandalan yang tinggi agar dapat menjaga kualitas dan ketahanan suatu sistem tenaga listrik terhadap gangguan. Salah satu sistem koordinasi proteksi yang sangat penting adalah sistem proteksi terhadap arus lebih dimana dapat melindungi sistem dari gangguan arus lebih sampai gangguan hubung singkat. Namun demikian energi yang ditimbulkan oleh adanya insiden busur api juga perlu untuk dipertimbangkan agar tidak menghasilkan energi yang terlalu besar sehingga dapat membahayakan pekerja. Analisa dan perhitungan insiden busur api berfungsi untuk menentukan jarak aman pekerja ke peralatan listrik dan juga pelindung apa yg harus dikenakan oleh pekerja ketika berada di sekitar peralatan listrik. Dalam penelitian ini dilakukan studi tentang kelayakan sistem koordinasi proteksi arus lebih dengan mempertimbangkan arc flash pada PT. Medco E&P Lematang Analisa busur api dilakukan dengan menggunakan standart IEEE 1584-2002. Analisa dan simulasi akan dilakukan menggunakan software ETAP Power Station 12.6. Dari hasil analisa, pada sistem koordinasi proteksi kondisi eksisting terdapat kesalahan pada grading time antar rele yang terlalu cepat sehingga perlu dilakukan setting rele kembali sesuai standart agar tidak terjadi kesalahan trip. Dengan melakukan pengaturan ulang didapatkan hasil sistem koordinasi yang sudah tepat. Setelah itu dilakukan evaluasi insiden busur api pada bus dengan level tegangan 6,6 KV. Dari hasil evaluasi menunjukkan adanya penurunan insiden energi sebesar 0,34 – 1,46 cal/cm2 di beberapa bus.

A protection system must have high reliability in order to maintain the quality and resistance of an electric power system to interference. One of the most important protection coordination systems is the overcurrent protection system which can protect the system from overcurrent disturbance to short circuit interference. However, the energy generated by the arc incident also needs to be considered so as not to produce energy that is too large so that it can endanger workers. The analysis and calculation of the arc incident serves to determine the safe distance of workers to electrical equipment and also what protection should be worn by workers when in the vicinity of electrical equipment. In this study a study of the feasibility of an overcurrent protection coordination system by considering the arc flash at PT. Medco E&P Lematang Arc analysis is carried out using the IEEE 1584-2002 standard. Analysis and simulation will be carried out using ETAP Power Station 12.6 software. From the results of the analysis, in the existing condition protection coordination system there is an error in the grading time between the relay which is too fast so that the relay setting needs to be done according to the standard so that no trip error occurs. By rearranging the results of the coordination system is already right. After that an evaluation of the incident arc on the bus with a voltage level of 6.6 KV. From the evaluation results showed a decrease in energy incidences of 0.34 - 1.46 cal / cm2 on several buses.
