(OP)
thread238-138519: Step Potential Higher than Touch Potential ?

To mitigate risk of step and touch potential how far the pavement area shall be extended from substation fence? If we provide mesh of 3 feet outside fence, do we still have to extend pavement (with coarse stone 8 inch layer)outside fence?

RE: Pavement distance around Substation fence

If you don't extend the stone 3 feet outside the fence, then you have to use a reduced allowable touch-voltage outside the fence.  The mesh 3 feet outside the fence will reduce the touch-voltage, so meeting the reduced allowable may not be a problem.
