Electricity 101

HOW FUEL IS TRANSFORMED INTO ELECTRICITY

 

electricity-supply-transmission_0.jpg

1. Fuel generates energy.

  • Electric power generation starts with a source of fuel that can be harnessed to create energy.
  • Fuel types include fossil (coal, oil, natural gas), nuclear, and renewable (such as solar power, wind power, falling water for hydro generation, and even garbage and agricultural waste products). Renewables also reduce emissions during power generation.

2. Turbine and generator convert energy.

  • In a power plant, the turbine and generator convert mechanical energy into electrical energy.
  • First the fuel produces steam, gas, or fluid that moves the blades of a turbine, so it revolves fast—more than 3,000 times a minute.
  • The spinning turbine is connected to the rod in a generator that turns a large magnet surrounded by coils of copper wire.

3. Generator magnet causes electrons to move and creates electricity.

  • The fast-revolving generator magnet causes electrons around the copper coils to move
  • The movement of these electrons through a wire is electricity

4. Transformer increases power voltage.

  • Thick wires carry the electric current from the generator to a transformer, which increases the voltage of the electric current to 500,000 volts or more, before electricity can be sent to the power grid

5. High-voltage lines carry the current to substations on the power grid.

  • From the power plant, the electric current travels on high-voltage transmission lines to an interconnected network of substations throughout your nation, called the grid.
  • At each substation, transformers decrease the electric current voltage to levels that can be used by factories, shopping malls, and other customers.

6. Power lines distribute to local transformers.

  • Buried or mounted on poles, distribution lines from the grid carry electricity from substations to smaller, local transformers.
  • Local transformers, mounted on poles or on concrete pads, further reduce the electric voltage to 110–220 volts, which can be used safely in businesses and homes.

7. Meters and controls for customer power.

  • Electricity typically enters your business or home through a meter that measures the amount of electricity you use. There, a control panel distributes power through wires in the walls and then to wall switches and outlets.
  • When you switch on or plug in equipment or an appliance, you complete the circuit from the power plant, and electricity operates your appliances and lights.

WHAT CAUSES LIGHTS TO FLICKER?

If you come home and find your clock-radio flashing 12:00, it's not necessarily a signal that your power has been out.

Most electrical disturbances last just a moment. A tree branch may have brushed against a power line or an animal may have scampered across it. When that happens, your local electric cooperative goes to work to make sure its lines aren't being damaged - because damaged wires can mean prolonged power outages.

When something lands on a power line, an oil circuit recloser (OCR) opens to interrupt the flow of electricity - sort of like your circuit breakers do at home. Once the equipment senses that the problem has moved on, the OCR closes and electricity is restored. On a rainy or windy day, this may happen repeatedly.

Still, it's better than the alternative - a damaged line that requires homes to be without electricity while it's being repaired. It's sort of an insurance policy for you and your electric co-op.

ELECTRICITY IS DANGEROUS

Accidentally contacting electricity or a power line can be dangerous and in some cases, even deadly. WCEC wants to help our members stay safe around electricity and power lines.

Contact with electricity can:

- Paralyze your muscles
- Burn you badly
- Stop your breathing
- Stop your heart
- Kill you

Keep a safe distance.

Whether you are playing outdoors with your children or working on landscaping projects, keep a safe distance from the power lines, pad mount transformers and other equipment used to get power to your home.

FOR YOUR OWN SAFETY

  • Stay away from power lines, meters, transformers, and electrical boxes. Remember to look up when working with tall objects or on rooftops.
  • Don’t climb trees near power lines. Never fly kites, remote control airplanes, drones or balloons near power lines. If you get something stuck in a power line, call your local utility.
  • Never touch or go near a downed power line. Don’t touch anything that may be touching a downed wire, such as a car.
  • Don't step out of the car if a power line falls on it.
  • Don't dig without checking for underground power lines. Call Before You Dig.
  • Don't put anything in the power outlet that wasn't intended for it.
  • Don't touch electric appliances when you are wet or near water.
