  • Grounding of the power distribution box of the iron tower

    Grounding of the power distribution box of the iron tower

    Pipe Earthing: Involves using a 25 mm diameter galvanized steel pipe buried 3 meters into the ground with layers of charcoal and salt for moisture maintenance. Counterpoise Earthing: Utilizes a 10. Protective grounds must be installed so all phases of lines or cable are visibly and effectively bonded together in a multi-phase. The purpose of transmission line grounding is to (a) provide adequate lightning performance of the line; and (b) effectively dissipate fault current avoiding the build-up of unsafe step and touch potentials around the tower base. The most important part of grounding is to protect people, structures, and equipment since damage can cause. Transmission tower grounding safety is a critical element that significantly impacts the reliability and sustainability of power grids. Tower grounding resistance is a significant grounding characteristic parameter.
