What Is Known As Electric Substations?

Substations are a familiar sight at the side of cities and highways. Substations take the electrical energy from the transmission lines and from power plants and transform it from high to a lower voltage. They distribute electricity to customers and supervise and defend the distribution network to keep it working efficiently and safely, for instance by using circuit breakers, that is, the industrial strength equivalent of the humble fuse for cutting power in case of a problem.

Substations are often classed as per the switchgear made use for protecting their circuits.

  • Air-insulated switchgear or also known as by the abbreviation AIS, is used to be the most ordinary design, although this needs a lot of space and for higher voltages is only reasonable outdoors. Even then, AIS or Air insulated switchgear might be unsuitable or undesirable in certain locations, such as residential areas.
  • Gas-insulated switchgear or also called as by the abbreviation as GIS might be more expensive if only the unit cost is measured up to, but is safer and requires less maintenance. The information that GIS units are five times smaller than AIS means cost savings and less or smaller intrusive buildings.

Electrical lines could be underground or overhead. The construction of overhead lines charges less, but outages are more common than on the underground lines, that is owing to the accidents, lightning strikes or bad weather.

What is found in an Electric Substations ? The equipment or tools found in switching devices and power transformers. Switching devices which are found in a substation are circuit breakers and dis connectors. Both these are used for cutting power in case of a problem, and measurement, defense and control equipment required for ensuring its safe and well organized operation. Since they are highly useful both commercially and residentially, therefore, they must be manufactured properly.
