A Simple Design Method of Unequal Spacing Arrangement for Substation Grounding Grid
IEEE Access, 2021 To balance the potential distribution on the surface of a substation, an equal spacing arrangement of the grounding grid conductors is not an economical solution. The implementable solution is an unequal placement of its constituent elements.
