How substations work and why are they called substations? A substation is used to transmit voltage and to distribute. Substations have a variety of function and we will discuss it in this article, also how is it working and the safety devices that used in substations. We usually had known that a substation is where we wait for a train and ride it to the other station. A large amount of electricity needs to be transmitted and distributed where it needs to be and it can be far from the substation. The power that is in substation is in high voltage and will step up using the transformers; they will step down for distribution after the transmission.
The substations used a variety of devices for protection such as fuses and circuit breakers for the safe distribution of the network. The substations are designed in a way that the distribution circuit can isolate and for repairs. Most of the substations are outdoors with a wire fence enclosing it, but in residential areas, the substations are inside or in indoors to control the noise of large transformers. There are companies that constructing substations where it needs and also took care of the maintenance of your substations to ensure your safety.
The substations have many functions aside from distributing electricity and these are to step up the voltage of the electricity for the transmission and to step down for the distribution. The power transmitted in high voltage the energy is lower it results in lower transmission losses, therefore it needs to step up and to step down the power. For maintenance, the substation needs to be switch and isolate. Switching of a substation is important when the demand of electricity is high, but it is dangerous, that’s why they used circuit breakers. They used special circuit breakers like oil circuit breakers and air circuit breakers.
To maintain the balance of distribution circuit of a substation, load shedding is what they do when the demand is more than the supply of the electricity. The electrical energy is generated in a thermal power plant, nuclear power plant and in hydroelectric plant, and then it supplies the substation for transmission. Using the step up transformer, the voltage of the electricity will increase substantially and it reduce to spread in far places.
The people should avoid living near the substations, because they can be exposed in radiation that will be a cause of many diseases like cancer and tumors. more info
