Equipotential Bonding
Equipotential Bonding is the practice of intentionally electrically connecting all
earthed systems to the same grounding grid or connecting the grounding grids of
all the earthed systems together through the ground or overground metal so as
to create an earthed equipotential zone. When lightning occurs, the high voltage
produced by lightning current in all systems will meanwhile exist in their ground
cables, and thus all ground cables have the same electrical potential and basically
eliminate the electric strikes between the systems.
The figure bellow illustrates how to practice equipotential bonding in a network.
