Abstract

Implementasi Sistem Grounding Resistansi Tinggi Untuk Mereduksi Arus Gangguan 1 Fasa Ketanah Pada Sistem Kelistrikan PT Petrokimia Gresik Aries Tri Apriliyanto I Made Wartana Ariestria19@gmail.com ABSTRAK Tingginya gangguan arus hubung singkat dapat membahayakan pada generator dan mahkluk hidup pada area generator, oleh karena itu diperlukan pentanahan NGR (neutral grounding resistance) untuk mereduksi arus hubung singkat satu fasa ketanah tidak melebihi batas aman yang diizinkan sesuai dengan IEEE C37.101 -2006. Dengan metode penggunaan sistem pentanahan NGR (neutral grounding resistance) arus gangguan hubung singkat satu fasa ketanah dapat direduksi dengan menentukan nilai resistance NGR, Sehingga arus gangguan tidak melebihi standart yang telah diizinkan IEEE C37.101 -2006. Hasil simulasi penggunaan NGR (neutral grounding resistance) di PT PETROKIMIA GRESIK dapat mereduksi arus hubung singkat dengan nilai resistance NGR sebesar 346 Ω dengan demikian arus gangguan hubung singkat dapat direduksi berkisar 10 A sehingga tidak melebihi batas aman yang diizinkan, sehingga tidak membahayakan pada Generator. Kata kunci : (solid) grounding,NGR (neutral grounding resistance),generator. Implementation of High Resistance Grounding Systems to Reduce Disruption of the Ground Phase 1 Interference in PT Petrokimia Gresik Electrical System Aries Tri Apriliyanto I Made Wartana Ariestria19@gmail.com ABSTRACT The high disturbance of short circuit currents can be harmful to the generator and living things in the generator area, therefore it is necessary to ground NGR (neutral grounding resistance) to reduce the ground phase single phase short circuit not exceeding the safe limit permitted in accordance with IEEE C37.101 -2006. With the method of using the NGR (neutral grounding resistance) grounding system, one phase ground fault short circuit can be reduced by determining the resistance value of NGR, so that the fault current does not exceed the standard permitted by IEEE C37.101 -2006. The simulation results of the use of NGR (neutral grounding resistance) at PT PETROKIMIA GRESIK can reduce short circuit currents with the value of NGR resistance of 346 singkat thus short circuit fault currents can be reduced in the range of 10 A so as not to exceed the safe limit, so that the Generator is not harmed. Keywords : (solid) grounding, NGR (neutral grounding resistance), Generator.
