How is electricity transferred from power stations to homes?
How is electricity transferred from power stations to homes?
The electrical charge goes through high-voltage transmission lines that stretch across the country. It reaches a substation, where the voltage is lowered so it can be sent on smaller power lines. The electricity travels through wires inside the walls to the outlets and switches all over your house.
How does a gas-fired power station work?
As hot combustion gas expands through the turbine, it spins the rotating blades. The rotating blades perform a dual function: they drive the compressor to draw more pressurized air into the combustion section, and they spin a generator to produce electricity.
Who is responsible for main electric line to house?
Electricity distribution companies are responsible for the network of power lines, underground cables, substations etc., that get electricity to your home or business in the area where you live.
What is a disadvantage of a gas-fired power station?
Gas-fired power stations
| Gas-fired power stations | |
| Advantages Shortest start up time Produces least pollution between oil, gas and coal | Disadvantages Non renewable fuel-limited and will run out Produces carbon dioxide and sulphur dioxide |
How does natural gas get to my house?
Natural gas companies drill thousands of feet into the earth and use big wells and pumps to bring it to the surface. Then they send the gas to your town through gas mains buried underground. Utility companies bring it to your house in smaller pipes.
How is electricity produced in a power station?
1. The fuel is burned to boil water to make steam. 2. The steam makes a turbine spin. 3. The spinning turbine turns a generator which produces electricity. 4. The electricity goes to the transformers to produce the correct voltage. Power stations generate significant heat losses to the environment.
What does the one line diagram of a generator look like?
The one-line diagram shows a simplified arrangement of the primary electrical components. A more detailed discussion of each component follows this narrative. Starting at the upper left corner of the diagram, a circle symbol with a Y in the center represents the plant main electrical generator.
What are the parts of Westinghouse generators?
Westinghouse generators use a brushless exciter system. Stator: The Stator has two primary parts: the stator core and the armature windings. The core is constructed out of donut shaped laminated iron alloy sheets that have slots around the inner circumference.
What are the characteristics of a power plant?
The utility operating the power plant is in the business of generating electrical power twenty four hours a day, seven days a week. Since electrical power can not be economically stored the plants must be online to produce power when the electrical demand is present. In this regard, the power plants must be highly reliable.
