What could happen during power transmission if the voltage is too high?

The amount of current in a circuit depends on the voltage supplied: if the voltage is too high, then the wire may melt and the light bulb would have “burned out real time”. Similarly other electrical devices may stop working, or may even burst into flames if an overvoltage is delivered to the circuit.

What happens if you touch a transmission tower?

Unless there is sufficient insulation (electrical impedance) between you and the earth when you touch a high voltage wire, yes you may get electrocuted. This is because most electrical power systems in the world are earth grounded (referenced to earth).

What happens if you touch one power line?

The main objective of electricity is to reach the ground and it will always try to get to the ground by the easiest, most direct route. If you are in contact with an object that is somehow touching a power line, then you may become part of the path to the ground and be electrocuted.

How many volts does a transmission line have?

Transmission line voltages vary from 44,000 to over 765,000 volts. The higher the voltage, the more electricity the line can carry.

How high are high voltage transmission lines?

Higher voltages on power lines require more space between each line and other objects, allowing people, vehicles and other equipment to move freely underneath. For this reason, transmission towers usually stand 55 feet to 150 feet high. Most are made from steel, but some are concrete, wood or even ductile iron.

Why does electric current cause death?

Contact with electric voltage can cause the current to flow through the body, which can then result in electric shock, burns and even death. This can happen in different scenarios or situations. If two cables have different voltage, the current can flow through them if they are connected.
