High-tension contacts form a “Voltage funnel” underneath the equipment and in a circle around it. The voltagedecreases as the radius increases. Every step within the voltage funnel is hazardous.A step can span two different potentials (step voltage),so that the current flows through the body in proportionto the potential difference. If a high-tension contact occurs, keep calm, stand still(step voltage), and don’t touch anything. No-one else should enter the hazard area. Immediatelyhave the high-tension cable switched off. After the high-tension cable has been switched off,move the machine away, help the injured and performfirst aid. Using remote control protects the machine operator onlyif he is standing outside the voltage funnel.In all other cases all personnel risk fatal injury. When working close to high-tension overhead cables, have these switched off by competent electricians.2.12.2.1 Automatic reconnection Electrical supply systems are equipped with automatic reconnection. After the switchgear has tripped, the short-circuited cable is automatically reconnected after a brief interval. It is therefore necessary to arrange permanent disconnection.5 . 0 0 0 V1 0 . 0 0 0 V1 5 . 0 0 0V20.000VFig. 2.15 Step voltage
