dc.description.abstractEarthing system is an important role for every substation. it protects the equipment and the safety of personnel work in the substation during fault occur or lightning strike. To design a safe and economical earth grid, it is necessary to calculate the distribution of fault current in a substation. Split factor is a main consideration when design a safe and economical earth grid. In this study, a substation earth grid was designed by using CDEGS and carry out in MALT. The energized fault current is 5000A and varied into 100%, 75%, 50% and 25% to investigate the impact on safety level of the substation. There are 2 type of earth grid was designed and 3 scenarios were carried out by the both type of earth grid. The first earth grid consists of 7 parallel conductors in row and 9 parallel conductors in columns. Second earth grid consists of 11 parallel conductors in row and 13 parallel conductors in columns. Both of the earth grid conduct with 354Ω-m, 1000Ω-m and 3000Ω-m resistivity of soil surface layer. Result indicated that 25% of fault current flow into second type of earth grid in three scenarios are safe. Although substation hard to meet safety criteria while the resistivity of soil surface layer is high.en_US
