¿Qué es alta tensión? » su definición y significado

Anonim

En electricidad, la tensión se define como el voltaje con que la electricidad se traslada de un cuerpo a otro. Cuando este voltaje es mayor a los 650 voltios se dice que existe alta tensión. La alta tensión se emplea en la distribución y transferencia de energía eléctrica, en el suministro técnico y en estudios científicos.

In order to transfer energy over long distances, reducing losses and increasing the transported power, it is necessary to increase the transport voltage. The localized voltage in the transmission circuits can range from 69 KV to 750 KV. A rise in the same would represent a decrease in the energy that circulates through the line, to transfer the same intensity, causing losses due to heating of the conductors, since the higher the voltage, the lower the intensity, which would bring a small energy loss.

The fact that these high voltage lines harm the environment and the people who live near them is under discussion, since it is thought that the radiation they emit affects health. On the other hand, it is said that electromagnetic pollution makes possible economic savings for companies or organizations in charge of distributing electricity, by transferring energy to a high voltage.

High voltage lines are classified as:

Third category: voltage greater than 1,000 and equal to or less than 30,000 volts. Its main utility is for generation and distribution.

Second category: greater than 30,000 and equal to or less than 66,000 volts. It is used for transportation.

Top-notch: greater than 66,000 and less than 220,000 volts. It is used to transport long distances.
