摘要
In this paper, the soil resistivity has been measured in the vicinity of a power station which situated near Brunei Liquefied Natural Gas (BLNG) of the Belait District. According to IEEE 81-1983 standard, the soil resistivity of this substation is measured using the equipment Fluke 1625. The measured soil resistivity data are then used into the CYME GRD software to calculate the soil resistivity and is found to be 63.8 ohm-m. Rectangular grid with the dimension of 50 m by 32 m is considered for the simulation of ground resistance, ground potential rise, touch and step potentials based on the IEEE 802000 standard. The simulation result of ground resistance, ground potential rise, tolerable touch and step potentials are found to be 0.66 ohm, 11061.2 V, 1171.3 V, 4193.10 V respectively. The simulation results are then compared with the calculation results using MATLAB GUI and are found in good agreement.
