Electrical energy

Electrical energy
It is a form of energy that is transported by an electrical current. Electricity is the most useful in the world for two reasons:

⤷It can be transformed into other types of energy so better than others.
⤷It can be transported over long distances cheapest and more efficient.

ELECTRIC POWER STATIONS.

A power station is a place when energy from natural resources is transfromed in the energy that we may use. Depends of the energy we will generate , recives a name or another.
How the electricity is generated?

If we want transform the energy into electricity, we usegenerators and if generators are used in power stations ,are called alternators. An alternator is make up by a stator and a rotor. The rotor has an even numbers of coils that receive direct current. They produce an electromagnetic field . Aturbine turns the axis of the rotor and generate electric current. This system is used at all power stations except for photovoltaic stations.


THE TRANSPORTATION AND DISTRIBUTION OF ELECTRICITY.

Power stations, usually, are place in zones far than the áreas where we use the electricity for safety reasons, for need space or for geographical features.
Electrical energy cannot be stored. There re many steps in the progress of transportation of energy:

1 Raising the voltage: the voltage is raised ,by transformers to high voltajes, because the electricity must go over large distances.

2 High voltage lines: the routes that the towers where are intalled the lines are carefully planned.

3 Reducing the voltage: The substations ,which are installed between the high voltage lines and final consumers, use Transformers to reduce the power to lower voltages.

4 Finally the power is distributed to buildings, industries and public installations. Te electric lines are installed in posts or underground. The voltage is reduced, depending on the final cosumer.
