ABSTRACT ABSTRACT ABSTRACT ABSTRACT The grounding system is an important component in protecting substation components. This is a connection scheme between embedded conductors connected to each other in the system, component bodies, and devices through grounding to protect the human body from electric shock and the installed parts from abnormal voltages and currents. The grounding system that is often used in substations is the grid and rod grounding system. This study analyzes the grounding system at GITET 275 kV Perawang, which has a grid system with the same spacing, and analyzes it using the unequally spaced grid method using ETAP 12.6.0 software to produce a comparison between the two grounding system models based on IEEE Standard 80-2000. The method used is data collection. The data obtained is then processed and calculated using ETAP 12.6.0 software. The grounding system at GITET 275 kV Perawang uses a grounding system with the equal method (equally spaced), a combination of grid and rod with a rectangular design with dimensions Lx = 144 m and Ly = 95 m and total conductors Nx = 15 and Ny = 25, with conductor rods located in each corner. This design is not safe for a body weight of 50 kg; it is only safe for a body weight of 70 kg. Design modifications were made to the Perawang 275 kV GITET, and a safe design was produced, namely f/Lx 144 m, q/Nx 17, g/Ly 98 m, and p/Ny 32 with a total conductor length of 5,629 m. This design is safe for 50 kg and 70 kg of weight. The permitted touch voltage is 1887.7 V, and the allowed step voltage is 7058.8 V for a 50 kg weight. Permitted touch voltage is 2555 V, and step voltage is allowed at 9553.8 V for a weight of 70 kg. The design using the unequally spaced grid method is the most economical when applied to the Perawang GITET 275 kV grounding system because this model grounding system has a total length of conductors that is less but still in a safe system condition of 3,750 m. The actual touch voltage is 1554.1 V for a weight of 50 kg, and the actual step voltage is 2504.1 V for a weight of 70 kg.
