Abstract
Miskoordinasi proteksi terjadi ketika relay tidak bekerja selektif sehingga perangkat hulu dapat trip bersamaan atau lebih cepat daripada relay hilir. Kondisi ini tidak hanya menurunkan keandalan sistem, tetapi juga memperbesar dampak gangguan, termasuk potensi munculnya arc flash. Arc flash merupakan fenomena pelepasan busur api listrik yang keluar ke udara dan mengalir melalui konduktor antar fasa atau fasa ke tanah. Analisis arc flash perlu dilakukan guna menentukan Personal Protective Equipment (PPE) sebagai langkah menjaga keamanan pekerja dan lingkungan dari potensi bahaya akibat energi yang terpancar selama terjadinya arc flash. Permasalahan miskoordinasi dan tingginya risiko arc flash ditemukan pada perusahaan eksplorasi dan produksi migas di Sumatera Selatan, di mana beberapa relai menunjukkan ketidakselektifan. Penelitian ini menggunakan standar IEEE 1584-2002 untuk simulasi dan analisis arc flash, metode kurva syarat batas energi sebagai analisis tambahan terhadap tingkat bahaya arc flash, serta standar NFPA 70E-2018 untuk penentuan kategori PPE. Pemodelan sistem, simulasi koordinasi proteksi, dan simulasi arc flash dilakukan menggunakan perangkat lunak ETAP 21.0.1. Hasil penelitian diharapkan memberikan rekomendasi setting proteksi yang lebih selektif serta kategori PPE yang sesuai pada area berisiko.

Protection miscoordination occurs when protective relays fail to operate selectively, causing upstream protective devices to trip simultaneously with or earlier than downstream relays. This condition not only reduces power system reliability but also increases the severity of disturbances, including the potential occurrence of arc flash. Arc flash is a phenomenon in which an electric arc is released into the air and flows through conductors between phases or from phase to ground. Arc flash analysis is required to determine the appropriate Personal Protective Equipment (PPE) to ensure the safety of personnel and the surrounding environment from the hazards associated with the thermal energy released during an arc flash event. Protection miscoordination and the high risk of arc flash were identified in an oil and gas exploration company in South Sumatra, where several protective relays exhibited non-selective operation. This study employs the IEEE 1584-2002 standard for arc flash simulation and analysis, the Energy Boundary Curve Method as an additional approach for evaluating the level of arc flash hazard, and the NFPA 70E-2018 standard for determining the appropriate PPE category. System modeling, protection coordination analysis, and arc flash simulations were carried out using ETAP 21.0.1 software. The results of this study are expected to provide recommendations for more selective protection settings and appropriate PPE categories for high-risk areas.
