Abstract

ABSTRAK Setiap pusat listrik yang baru dibangun, harus memiliki sistem pentanahan yang handal. Setiap pembangkit listrik harus memiliki sistem pentanahan yang handal untuk mengamankan peralatan dan manusia. Penelitian ini bertujuan untuk merancang sistem pentanahan grid-rod yang memenuhi standar aman sesuai ketentuan IEEE std. 80-2000 pada Pembangkit Listrik Tenaga Mesin Gas (PLTMG). Perancangan sistem pentanahan ini berlokasi di Seram, Masohi, Maluku dengan data tahanan jenis tanah sebesar 38,8 Ω.m, arus gangguan maksimum ke tanah sebesar 50.489 Ampere. Dalam analisis dari pentanahan PLTMG 20 MW menggunakan perhitungan manual dan software ETAP 12.6.0. Hasil penelitian menunjukan bahwa nilai tahanan pentanahan (Rg) sebesar 0,49 Ohm, tegangan sentuh (Em) sebesar 5185,5 Volt, dan tegangan langkah (Es) sebesar 1645,23 Volt. Perancangan sistem pentanahan PLTMG Seram, Masohi, memenuhi persyaratan aman IEEE Std. 80-2000. Kata kunci : Sistem pentanahan, Tahanan pentanahan, Tegangan sentuh, Tegangan langkah ABSTRACT Each newly constructed power plant must have a grounding system. Every power plant must have a reliable grounding system to secure equipment and people. This study aims to design a grounding system with grid-rod design to get a value that meets safe standards according to IEEE Std 80-2000 at a gas engine power plant. Design of grounding system located at Seram, Masohi, Maluku with a soil type resistance of 59,6 Ω.m, the maximum disruption current to the ground is 50.489 Amperes. In the analysis of grounding system at a gas engine power plant using manual calculation and simulated on software ETAP 12.6.0 The result showed that the value of grounding resistance (Rg) of 0,49 Ohm, the tension stress (Em) of 5185,5 Volt, and the step voltages (Es) of 1645,23 Volt. The design of grounding system located at Seram, Masohi Maluku meets the safe requirements of IEEE Std 80-2000. Keywords : Grounding system, Grounding resistance, Touch voltage, Step voltage
