This calculator is designed for electrical engineers to calculate the grounding grid resistance of substations based on IEEE Std 80. It helps ensure safety and compliance in power system designs.
All calculations are based on IEEE Std 80. The standard provides guidelines for the design of safe and effective grounding grids.
\[ R = \frac{\rho}{L} \times \ln \left( \frac{L + \sqrt{L^2 + W^2}}{W} \right) \]
For a grid with length 100m, width 50m, and conductor size 150mm², the resistance is calculated using the formula above.
IEEE Std 80 is a standard that outlines the requirements for substation grounding design to ensure safety.
The conductor size is typically determined by the current carrying requirements and mechanical strength needs.
Grounding ensures safety by preventing electrical shock hazards and equipment damage.
Soil resistivity, grid geometry, and conductor material all affect the grounding grid resistance.
This calculator is based on IEEE Std 80 and is applicable to designs that adhere to this standard.
