TRANSPORT OF ENERGY

We just need to look around us to be aware of the importance of energy in our everyday life: the refrigerator, the telephone, TV, computers, hairdryers, washing machines, dishwashers, radiators, game consoles, etc.

But electricity cannot be stored, therefore, it must be transported from power plants to consumption centres: industries and towns.

A complete electricañl installation consists of six elements: The power station where electricity is produced. The power transformers, which raise the voltage of the electrical current to be transported with the least possible losses. The transmission lines. The substations, where the voltage is lowered to be distributed to customers. The distribution lines. The step-down transformers which lower the voltage to the level used by consumers.

Once electricicty gets to the cities, a distribution network which runs through the treets, buried in separate trenches, along with other supplies, is established.
