Abstract
Arc Flash yang terjadi pada sistem kelistrikan menimbulkan
kerugian yang sangat besar. Insiden energi yang dilepaskan dapat
merusak peralatan dan terutama dapat membahayakan pekerja yang
bekerja di lingkungan tersebut. Perlu sistem pengaman yang mampu
mengatasi gangguan tersebut. Koordinasi pengaman yang selektif tentu
akan mempertimbangkan jarak waktu antar pengaman untuk menjaga
kontinuitas serta stabilitas aliran daya ke lokasi yang tidak mengalami
gangguan. Permasalahan yang timbul adalah hal tersebut mengakibatkan
pengamanan dari Arc Flash belum efektif dalam mengurangi bahaya Arc
Flash. Sesuai dengan standar koordinasi proteksi, pengaman yang
semakin jauh dari beban setting waktunya akan diset relatif lebih lama
untuk menjaga selektifitas. Hal tersebut mengakibatkan insiden energi
Arc Flash akan besar. Zone Selective Interlocking sebagai sebuah metode
yang bekerja berdasarkan komunikasi antar pengaman menjadi solusi
yang sesuai dengan permasalahan tersebut. ZSI dapat mengurangi insiden
energi Arc Flash tanpa mengorbankan selektifitas dari koordinasi
pengaman sehingga kontinuitas daya tetap terjaga. Penerapan teknik ZSI
ini akan coba diterapkan pada sistem tegangan rendah 0.48 kV CPA
Petrochina mengingat pentingnya perusahaan tersebut mengamankan
peralatan serta pekerjanya dari insiden energi Arc Flash yang besar.

Arc flash that occurs on the electrical system causing huge losses.
Incident energy released can damage equipment and endanger workers
employed in these environments. We need a protection system that is able
to cope with the disorder. Selective coordination of protection which will
consider the intervals between the protective device to maintain the
continuity and stability of the power flow is not susceptible to
interference. The problem that arises is that system is not effective in
reducing the impact of arc flash hazards. In accordance with the
standards, the low voltage protective device away from the load will set
a relatively long disruptions to maintain selectivity, but its impact is arc
flash incident energy will be higher. Zone Selective Interlocking as a
method based on the communication between protective device give
solutions that fit the problem. ZSI can reduce Arc Flash incident energy
without sacrificing selectivity of protection coordination so that the
continuity of power is still safe. So we try apply this ZSI to the low voltage
system 0,48 kV CPA Petrochina to give secure for workers and the
equipment from high Arc Flash incident energy.
