Abstract
PT. Semen Padang sebagai salah satu produsen semen terbesar di
kawasan Indonesia bagian barat, seiring dengan perkembangan industri
semen PT. Semen Padang melakukan penambahan pabrik baru Indarung
VI untuk menunjang proses produksi. Dengan penambahan beban muncul
permasalahan pada sistem kelistrikannya, yaitu sering terjadi kegagalan
proteksi pada trafo utama yang ada di GI Semen Padang pada saat terjadi
gangguan, sehingga kontinuitas daya ke beban terganggu dan
mengakibatkan pemadaman yang lebih luas. Melalui tugas akhir ini
dilaksanakan studi koordinasi proteksi pada PT. Semen Padang yang tepat
dalam mendeteksi dan mengisolir gangguan sehingga tidak mengganggu
sistem yang sedang berjalan dan mencegah kemungkinan terjadinya
kerusakan peralatan listrik.Dari hasil plot koordinasi kurva arus waktu
kondisi existing setting koordinasi rele arus lebih fasa masih ada
kesalahan koordinasi sehingga perlu dilakukan evaluasi ulang untuk
mendapatkan hasil resetting yang bisa direkomendasikan sebagai setting
rele pengamannya. Melalui hasil analisis dan perhitungan manual
direkomendasikan penyetelan pick up rele arus lebih dan penyetelan
grading time . Rele yang disetel ulang adalah rele arus lebih gangguan
fasa (overcurrent relay).

PT . Semen Padang as one of the largest cement plant in the
weastern of Indonesia , Along with development cement industry PT.
Semen Padang planning to add new plants Indarung VI to support the
production process. With the addition of load, problems occur in the
electrical system, the failure protection often occur in GI Semen Padang
during a fault, so the continuity of power is being interrupted. Through
this final project carried out the correct studies on the coordination of
electrical system protection in order to detecting and isolating the fault
so the running system is not disturbed and prevent damage to electrical
equipment. The results of time current curve in exisiting conditions can
be seen that there are misscoordination more phase relay current so that
need to re-evaluate to get resetting result which can be reommmended as
relay security setting. Through the analysis and manual calculation
result, give the recommendation to reset pick up setting and grading time
of overcurrent relays. Relays that need to be reset are phase fault
overcurrent relays.
