The Basics of Substation Grounding: Parts of the Grounding …
By using the grounding conductor, the ground connections of the two substations work in parallel; this is generally beneficial as it reduces the return of current through the ground, lessening the surface potential gradients. Without the grounding conductor, all ground-fault current from equipment 4 will return through the earth.
Indeed, if one employs a robust grounding design for a normally grounded system and ensures that the UPS and battery-cabinet enclosures are connected to the building''s grounding-electrode system through appropriately sized grounding electrode conductors, almost all requirements for an ungrounded system will be met …
