When the Shortest Path Is Not the Current Path

The same overhead-line corridor can behave like a distributed earthing network under 50 Hz earth-fault conditions, but like a local impulse-current problem under lightning conditions. That difference changes current paths, touch-voltage risk, and infrastructure stress.
