Abstract
Sistem kelistrikan yang aman dan handal merupakan salah satu tujuan utama yang harus terpenuhi dalam bidang industri. Dalam mewujudkan hal tersebut, dibutuhkan sistem proteksi yang efektif dan selektif dalam mengatasi gangguan pada sistem kelistrikan. Sejak dibangun, PT Pertamina JOB Medco Energi Tomori Field Senoro belum pernah dilakukan studi mengenai koordinasi proteksi. Oleh karena itu, perlu dilakukan studi koordinasi proteksi untuk menjamin keamanan dan kehandalan pada sistem kelistrikan di PT Pertamina JOB Medco Energi Tomori Field Senoro. Pada tugas akhir ini akan dilakukan perhitungan dan simulasi koordinasi proteksi pada sistem kelistrikan PT Pertamina JOB Medco Energi Tomori Field Senoro. Perhitungan yang dilakukan meliputi setting rele arus lebih dan rele diferensial. Grading time antar rele arus lebih dikoordinasikan dengan waktu minimal 0,2s . Di samping itu, sistem juga dilindungi dengan rele diferensial untuk mengatasi gangguan pada trafo. Slope pada rele diferensial trafo diatur sebesar 76% dan Idiff sebesar 2In. Dengan adanya setting koordinasi proteksi tersebut, sistem kelistrikan PT Pertamina JOB Medco Energi Tomori Field Senoro lebih aman dan handal.

Safe and reliable electrical system is one of the main goals that must be filled in the field of industry. To obtain the goal, the system needs effective and selective protection for overcoming electrical system fault. Since it was built, PT Pertamina JOB Medco Energi Tomori Field Senoro has been never studied about protection coordination. Therefore, it is necessary to study the protection coordination to ensure the safety and reliability of the electrical system in PT Pertamina JOB Medco Energi Tomori Field Senoro. In this final project the protection coordination on electrical system of PT Pertamina JOB Medco Energi Tomori Field Senoro will be calculated and simulated. The calculations includes setting of overcurrent relay and differential relay. Grading time between overcurrent relays are coordinated with the minimal time 0,2s. In addition, the system is also protected by the differential relay to overcome the transformer fault. Setting slope of transformer differential relay is set at 76%. While Idiff is set at 2In. By the settting of the protection coordination, electrical systems PT Pertamina JOB Medco Energi Tomori Field Senoro more secure and reliable.
