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 below illustrates how to practice equipotential bonding in a network.
