ABSTRAK

Sistem pengaman tentu dibutuhkan sebuah industri untuk menjaga kontinuitas pelayanan sistem kelistrikan. Hal ini tidak lepas dari pengamanan peralatan sistem kelistrikan. Pada perusahaan penghasil amoniak seperti PT.KPI Bontang memiliki banyak perangkat motor penggerak maupun pompa dengan daya yang cukup besar. Sistem kelistrikan tentunya diikuti dengan proses gangguan-gangguan yang dapat terjadi kapanpun dengan berbagai macam faktor salah satunya seperti short circuit. Penelitian kali ini akan membahas tentang sistem pengaman PT.KPI Bontang. Sistem pengaman pada PT.KPI Bontang kondisi existing masih memerlukan perbaikan setting time delay rele tidak sesuai dengan standar perhitungan belum adanya studi lanjut mengenai energi busur api yang tentunya penting untuk sistem pengaman kelistrikan PT.KPI Bontang. Kondisi awal analisa busur api pada main bus memiliki kategori 4 ini artinya energi busur api ketika terjadi gangguan short circuit sangat besar dan berbahaya. Pada penelitian ini akan dilakukan Resetting perhitungan busur api mencari incident energy yang dapat digunakan untuk menetukan flash protection boundary serta pada kondisi resetting koordinasi rele pengaman juga akan berpengaruh pada penurunan kategori busur api atau arcflash.


ABSTRACT

Coordination system will require an industry to maintain continuity of service of the electrical system. This is include of security equipment electrical systems. In the ammonia producing companies such as PT.KPI Bontang has a lot of drive motor and pump devices with considerable power. Electrical system must be followed by the disturbances which may occur at any time by a variety of factors one of them is like a short circuit. The present study discusses the safety system in PT.KPI Bontang. The coordination system at the Bontang PT.KPI existing condition still need improvement setting the time delay relay is not in synchronous with accounting standards the lack of studies about the arcflash energy is certainly important for electrical safety coordination system PT.KPI Bontang. Initial conditions arcflash analysis on the main bus has 4 categories this means energy arcing short circuit when an interruption is very large and dangerous. This research will be conducted Resetting calculating arcflash incident energy that can be used to determine the flash protection boundary and the safety relay coordination resetting conditions will also affect the decrease in arc or arcflash category.
