Abstract
ABSTRAK
Pengaruh arus gangguan berlebih pada sistem pentanahan yang tidak bagus dapat menimbulkan beberapa gejala seperti munculnya tegangan sentuh dan tegangan langkah serta berpengaruh pada nilai resistansi pentanahannya. Penelitian ini bertujuan mendesain sistem pentanahan dengan variasi Jumlah Konduktor dan Batang Rod tertanam dimana hal ini dapat memberikan dampak terhadap sistem pentanahan, yang mana dapat membantu mengurangi timbulnya arus gangguan berlebih serta mengurangi nilai tegangan sentuh dan tegangan langkah yang muncul. Metode penelitian yang digunakan dalam penelitian ini adalah Metode Wenner (metode empat titik) dimana metode ini digunakan dalam Mensimulasikan sistem pentanahan yang berpengaruh terhadap variasi jumlah konduktor dan Batang Rod tertanam menggunakan software CYMGRD (CYMGround Substation Program). Hasil pengujian menampilkan nilai maksimum tegangan sentuh sebesar 729,01 Volt dan nilai maksimum tegangan langkah sebesar 2423,88 Volt. Hasil simulasi menyatakan bahwa kondisi sistem pentanahan dengan variasi jumlah konduktor dan Batang Rod tertanam dinyatakan dalam kondisi aman.

ABSTRACT
Excessive fault current on a poor grounding system can cause several symptoms such as the appearance of touch and step voltage and affect the grounding resistance value. This study aims to design a grounding system with variations in the number of conductors and embedded rods where that can have a good impact on the grounding system, which can help reduce the occurrence of excessive fault currents and reduce the value of touch voltage and step voltage that appears. The research method used in this study is the Wenner Method (four-point method) where which method is used in simulating a grounding system that affects the variation in the number of conductors and embedded rods using CYMGRD (CYMGround Substation Program) software. The test results show that the maximum touch voltage value is 729.01 Volts and the maximum step voltage value is 2423.88 Volts. The simulation results state that the condition of the grounding system with variations in the number of conductors and embedded rods is stated in a safe condition.
