A Ground Potential Rise
A lightning strike to
any grounded structure or a high-voltage flashover from a power line to a grounded
structure will cause the ground in the vicinity to rise in voltage to dangerously high
levels, which can electrocute personnel standing on the ground in the area and damage or
destroy electronic equipment connected to ground.
Practicing what you learn here will allow your company or organization to cut costs, remain operational even under severe lightning conditions and may save your life or the life of a coworker.
