Unequally Spaced Grounding Grid of Substation Grounding for Enhancement of Human Safety and Cost Reduction

EasyChair Preprint 7308, version 1

Abstract

The authors offer a new approach for producing an unequally spaced substation grounding grid, in which the grid conductor spacing increases progressively from the perimeter to the centre. Formulas are used to compute the distance between conductors. It is explained how to make a grid with irregular spacing. The suggested approach can construct an unequally spaced grid that makes current density in conductors more uniform, resulting in considerable reductions in earth surface (potential) gradients. In addition, the grounding grid uses 30% less material. Numerical computations are used to determine the outcomes of field tests.

Keyphrases: Conductors, Substation design, Uneven spacing, contact voltage safe and affordable design, grounding grid, mesh potential, potential distribution
