What is electricity?

Watch and find out what electricity is and how it's made.

Transcript

Electricity is a common source of safe and reliable energy, it's an important part of our everyday lives. It gives the appliances in our homes energy so they can heat, cool, entertain, and cook for us. Most of the time, electricity is our friend, but sometimes it can be dangerous if we're exposed to it in ways we're not meant to. Hazards and accidents with electricity can be avoided by understanding how it works and by following some simple rules.

To understand how electricity works, we first need to know what a conductor is. A conductor is anything that allows electricity to travel along or through it, like metal. On the other hand an insulator is anything that does not allow electricity to pass through it, like rubber. Electricity is the flow of electrons through a conductor, like water through a hose. Unlike water, which is measured in litres, electricity has electron flow or current which is measured in amps. The pressure under which electrons flow, is known as voltage, and is measured in volts.

Generating electricity

This video explains how electricity is generated and delivered to your home.

Transcript

One way of generating electricity is by moving a magnet across a metal conductor.This typically happens in a power station. The energy needed to move the magnet comes from steam produced by burning coal. Electricity can also be generated from renewable sources such as water wind or the sun.

Electricity leaves the power station along high-voltage power lines. These are connected to transmission towers to get the electricity to your home quickly and efficiently, the electrical pressure, or voltage starts as high as five hundred thousand volts. By the time the electricity reaches your home the voltage has been reduced to 240 volts. This is the standard voltage in Queensland and makes it possible for us to use electricity safely in our homes. Some countries have different voltages for their electrical appliances, so when you travel you may need different plugs and special transformers.

The electrical circuit

This video explains what an electricity circuit is, how it works and how electric shocks happen.

Transcript

In electricity, electrons travel in a circuit or loop for an electrical appliance to work. The electricity needs to go in through wiring, do its job, then come out again and go back towards the power source. There must be a continuous circuit for the electricity to travel through for an electrical appliance to work. A switch is used to break a circuit,  so that you can turn electrical appliances and lights on and off.

If you interfere with an electrical circuit, electrons can escape and this isn't good. Electricity is safe and useful, when it's used properly, but if something happens an electrons escape out of their circuit they can use your body as a conductor to close the loop. You could get an electric shock which can be extremely dangerous, even deadly.

Keeping safe

This video explains how to keep safe around electricity poles, wires and underground cables.

Electricity poles and powerlines

This video explains the hazards surrounding electricity poles and powerlines.

Transcript

Everyone likes to play outside but there's electrical hazards that you should be careful of. Electricity poles and powerlines are all around us, they can be above us, beside us, or even below us. If you're flying a kite and it gets caught in overhead powerlines, live electricity could travel down the string and seriously hurt you. Always look up for overhead powerlines. Whenever you can play in open spaces, away from electricity poles towers and powerlines.

Never climb a tree that is near a powerline, look up before you climb. This also goes for the overhead lines which power electric trains and the large transmission towers you sometimes see. If electricity escapes at circuit it'll use your body as a conductor it'll travel through your body to the earth and you could get a severe shock. So never play on electrical equipment or in trees near powerlines. After a storm if you see something you think is a fallen powerline always assume it's alive with electricity running through it. Stay at least 10 meters away, tell an adult, and call triple zero (000). Remember to keep safe be careful around electricity poles and powerlines when you play outside.

Electrical emergencies

This video explains what to do in an accident or emergency that involves electricity.

Transcript

We all hope we're never involved in an accident or emergency involving electricity, but if we are, it's important to know what to do. If you come across a dangerous situation or emergency involving electricity, ensure your own safety first and always remember you must leave it to the experts.

If you see a broken power point or damaged cord on an electrical appliance, don't keep using it, switch the power off and unplug it, but only if it's safe to do so. Tell an adult so they can have a licensed electrical contractor repair the damage. If you're outside and you see something you think is a fallen powerline, always assume it's live with electricity running through it. Stay at least 10 meters away, tell an adult, and call triple zero (000).

Shocks and tingles can be a sign that something's wrong with the electricity supply. If you get a shock from an electrical appliance or a water tap, tell an adult so they can report the shock immediately. Remember to keep safe and know what to do in an electrical emergency.

Metal is a conductor

This video explains about the dangers of electricity coming into contact with metal objects.

Transcript

Metal is a conductor of electricity and can be dangerous. We all come into contact with metal objects on a daily basis, turning on a tap, using a computer, or even opening the fridge. Because metal conducts electricity, you should be very careful when you use metal items. Never put a metal object like a knife into a toaster and never put anything into a power point that's not meant to go in it. Electricity will travel through the metal object into your body and give you an electric shock.

You should also be careful when climbing ladders at home, the powerlines connected to your house are usually protected, but they can be damaged by rubbing against a gutter or a tree or through exposure to the elements like the sun, rain and wind. If someone is on a metal ladder and touches the exposed line, the electricity will travel through their body to the earth and give them a severe electric shock.

This car has been in an accident and is run into an underground power cable pillar box. It's in contact with an electricity cable but the driver is okay because she's not standing on the ground. If someone else touched the car or the driver tried to get out, they would be in contact with the earth. This would create a circuit electricity would travel through them and they would receive a life-threatening electric shock. Remember to keep safe metal is a conductor of electricity and can be dangerous

Electricity and water

This video explains the dangers of mixing electricity and water.

Transcript

Water conducts electricity, that's because electrons can flow by hitching a ride on atoms and molecules in the water. Water contains dissolved substances such as salts, these greatly increase the ability of water to conduct electricity. That's why electricity passes easily through our bodies, because they're made up of a lot of water. This is why it's so important to keep water away from electricity and electrical appliances.

If your hands tingle when you put them in the sink, it may mean the water is conducting electricity and something is wrong. Or if you get a tingle from the tap let mom or dad know, as they need to call a licensed electrical contractor. When you have a bath there should be nothing electrical anywhere near you. This means if a household appliance like this hair dryer fell into the bath, whoever was in it would also become a conductor of electricity and receive a severe electric shock. Remember to keep safe electricity and water don't mix.

Stay away from substations

This video explains the dangers of substations and why you should stay away.

Transcript

Electrical equipment and electricity substations are everywhere you look. They're behind fences, in buildings, or on the side of the footpath and most of them have danger signs. Substations reduce the voltage of electricity from power stations, so it can be distributed to homes schools and businesses. Sometimes they're near parks and play areas, so you need to be careful and follow the rules. It can be tempting to ignore signs and fences around substations, but remember the warnings are there for everyone's protection, so make sure you follow them.

Substations contain special equipment with invisible hazards, you don't even have to touch anything to get hurt, just being too close to some substation equipment can be dangerous and may even kill you. Remember to keep safe and stay away from electrical equipment and electricity substations.

Heroes at home

Watch how you can be a Safety Hero at home.

Transcript

My name's Anthony I'm with Ergon Energy. We're here to teach you a little bit about Electrical Safety. Now one of the things we're seeing at the moment is really important for you guys to remember, is if you're at home and you touch the shower, or you touch a tap outside and you get a little tingle, that's really important to tell mum. Then you need to go to a licensed electrical contractor or tell Ergon because something needs to be done straight away. And now what I'd like to do is go through some common problems that we see in home, but the first one I would like to get you to think about is if you see a power lead, it's all frayed and you can actually see the cables coming out.That again can be very very dangerous that's something that needs to be looked at by a licensed electrician. Other things that we kind of see at home too are your power point switches. If they're loose or got cracks in them, really important to have them fixed straight away because again that can cause electrical problems, you can get a zap off them. The other things that we see are, people when they get double adaptors and they piggy-back them altogether, that's very very dangerous. You should get rid of them straight away and go and get a Power Board to make sure you only have one plug in each, that's really, really important. And one of the things I taught my kids when they were young, if you're tasting something and it gets stuck don't ever put a knife or a fork in there. That could kill you. You need to go and tell mum and dad and make sure they turn the toaster off and then they can get the toast out for you. Really important.

Next up, I'd like to talk about electricity and how it can actually jump. Now you guys don't have to worry too much because the powerlines are right up high, but you could get a situation, you could be a safety hero if you saw dad, and he's out trying to cut a tree down out the front near the powerlines, you must remind and keep that away from the powerline, because it can actually jump and zap you.Now while we're talking about powerlines, if ever we had a situation where you've got a fallen powerline particularly around thunderstorm time, again, you don't even have to touch those wires, if you get close enough to them, they can still zap you. So if you ever you see a fallen powerline on the ground, you make sure you keep six meters away and immediately ring triple zero (000). And then triple zero will get on to us and we'll be able to come out and warn everybody else to stay away, that'd be really, really, helpful for us. So still on powerlines, if you were to have a kite and you're out there having a bit of a play, imagine if your kite got stuck on the powerlines. You might get a zap out of that too, or you might be climbing up in a tree you might get really close to the top. there might be powerlines running through. so always have a look around before you do anything, look around for powerlines that's really important as well.

So finally, I just like to remind you that water and electricity doesn't mix. Imagine if you've got a hair dryer next to your bath and you're sitting in the bath having a good time and someone bumps a hair dryer in, what do you think would happen? I don't let any electrical things in our bathroom because it is too dangerous. Or even if you notice someone's outside, maybe dad's out trimming the garden and he's got an extension lead that's going near the pool, no, you say stop, you must really be conscious of that. Really, really, important again, and if you want to learn more about Electrical Safety if you go to the Ergon website you'll see hero's at home page and that can help you become a safety hero.

Step and touch potential

This video explains step and touch potential.

Transcript

An easy way to understand step potential is to imagine a stone being dropped into a pool of still water. When the stone hits the water, it forms ripples that spread out from the point where the stone hit. The ripples are stronger at the centre, and gradually become weaker the further they travel.

The same thing happens with electricity if a powerline falls on the ground, or machinery or a vehicle contacts a powerline. If a mobile crane came in contact with an 11,000-volt powerline, the electricity surges to the ground, spreading outwards through the earth at the point of contact, just like the ripples in the water. The first ripple would be 10,000 volts, then 9,000, 8,000 and so on. If you're standing within a 10 meter radius of the crane and you've got one foot on the 8,000 volt ripple and the other foot on the 7,000 volt ripple you will receive an electric shock that can be fatal. This happens because high voltage will always travel towards low voltage and your body is a much better conductor than the ground.This is called step potential.

Touch potential is the voltage between the energised object, and the feet of a person touching that object. The touch potential is the full voltage of the energised object. If you were touching the crane you would receive the full 11,000 volts straight through your body. The safest place to be is at least 10 meters away from the crane, or inside the crane. This may seem illogical, but the metal crane is a much better conductor than your body - the electricity will flow through the metal first because it is a less resistant path. If you attempt to leave the vehicle you may receive an electric shock that could be fatal.

Remember, accidents do happen. If you’re in a vehicle, STAY inside. If you’re a bystander, STAY 10 metres away. CALL triple zero (000), and WAIT for help.

Vehicle accidents and powerlines

If you must leave your vehicle, use the following steps to protect yourself from electric shock.

Transcript

Vehicle accidents can bring down powerlines and cause damage to electrical equipment at ground level. It's important to remember that the vehicle, and anything else such as fences and trees in contact with powerlines, could be 'live'.

If you are in a vehicle accident that involves power lines remember:

Stay calm.

Treat all powerlines or any other electrical equipment as ‘live’

Stay in the vehicle until the power has been shut off and the powerlines removed. If you leave the car before the area is made safe, you risk being electrocuted.

Warn bystanders to stay a minimum of 10 metres away from the vehicle and anything else in contact with downed powerlines.

Don’t attempt to rescue or allow others to approach the vehicle if it is in contact or near downed powerlines.

STAY in the vehicle.

CALL triple zero.

WAIT for help.

So, what if it’s unsafe to stay in the vehicle?

If there’s immediate danger, like fire, assess your escape route and check for fallen powerlines.

  • Exit the vehicle by jumping away from the vehicle, with both feet together.
  • When jumping away, never touch the vehicle and the ground at the same time.
  • Once you have landed with both feet together, continue jumping in this manner - feet together, bunny hop style. Alternatively, move by shuffling with your feet together, and don’t let your feet leave the ground. This is to reduce the risk of being shocked by electricity travelling through the ground.
  • Continue moving away from the accident site in this manner until you are at least 10 metres away from the vehicle. Do not go back.

Remember, accidents do happen. If you’re in a vehicle, stay inside. If you’re a bystander, stay 10 metres away. Call triple zero (000) and wait for help.

Take care, stay line aware during storms TVC

Take care. Stay line aware. Call 000 (triple zero) or 13 16 70 if lines are down.

Transcript

There are lines that help with the everyday things, while others can quickly turn into something more dangerous. When storms hit look out for fallen powerlines. Take care, stay line aware, call triple zero (000) or Ergon.
