comment Why don't electric workers get electrocuted when only touching one wire?
Current doesn't flow when there's no potential difference. You don't 'lose' a potential difference when current is flowing; current flows because there is one. It will flow until something breaks the circuit, either a fault interruptor or your hand burns off.

Okay, let's assume that you've totally lost it and are tightrope walking across a bare hydro wire. There will be no appreciable potential difference across various points on your body. Your body will be at the same potential at the wire. This is true even if you take a large step, because there is (virtually) no voltage drop in the hydro line across the distance of one step. You need to jump off when you get to the end though.
