What is Earthing Design for 33/11kV Substation about?

The document provides calculations for the earthmat design of a new 33/11kV substation in West Bengal. It includes soil data, conductor specifications, switchyard dimensions, number of earth electrodes, and methodology for determining tolerable touch and step voltages, grid resistance, maximum grid current, ground potential rise, and attainable mesh and step voltages. The key findings are that the calculated mesh voltage is lower than the tolerable touch voltage, the calculated step voltage is lower than th
