Earth mat substation
WebMost affected parameters for design of Earthing. Grids are: a) Magnitude and duration of fault current. b) Soil and surface resistivity at the substation site (soil structure and soil Model ) Property and cross-section of material used for earth mat conductor. d) Earthing mat geometry (Area covered by Earth mat). Webvoltage panels. The earth mat is below substation which is almost 15-18-Meter-deep from ground level. The main considerable factors for earth mat design are soil resistivity which is higher due to basalt rock and system fault current. Fault current level of the system considered as 70kA derived from calculations. Earthing is essential for proper
