Abstract

The distribution of electrical energies has grown the economy, social, and education, so the reliability is very important, the grounding resistance that is lower than 5 ohms is required for the low voltage distribution system according to PLN standards. The Bali State Polytechnic Electrical Workshop, has a grounding resistance of 40 ohms, so this applied research with descriptive quantitative methods is carried out by 6 samples. The previous studies it has been explained that soil type, moisture, acidity level determine soil resistivity which affects grounding resistance. Natural soil found in the field has 70% humidity, acidity level of 6.2 has grounding resistance of 40 ohms on a 20 mm diameter rod electrode, stuck 1.2 m deep, so in this study natural soil reconditioned to decrease its acidity level. This study found that: Soil resistivity decreases when humidity increases from 70% to 100%; Soil resistivity also decreases when the acidity level drops to 3.8; and increase again when the acidity level is decreased. Natural soil reconditioned affect to decreasing the grounding resistance up to 241.67% when the acidity level was 3.8 while the previous researchers only examined up to the acidity level of 4.27.
