How does the power supply schematic for national grid operate

power supply schematic Have you ever heard of a term “National Grid”? Ever wondered what is the meaning of that grid? A national grid is basically a power supply schematic diagram of the whole country, it is the way that all the electricity lines are connected, supplied and delivered in your country. Here we are going to explain you the basics of how the electricity runs throughout starting from a generator, then being transmitted from a city to city and then finally being distributed.
First of all, for a power to flow through the power supply schematic diagram, the electricity has to be produced. It can be produced in various ways, it could be from a renewable or a non-renewable energy. A renewable energy is when we use the energy that cannot be depleted, for example, water, sunlight or wind. We can just keep on using the wind power to generate electricity and we are sure that the wind will never be depleted. For a non-renewable energy, a good example is crude oil. A big scandal nowadays is that, the oil resources of the earth are soon going to be finished and we won’t be able to use it anymore. However, non-renewable energy gives more power and therefore is more often used than the renewable energy.
After the electricity is generated, the goal of a power systems engineer is to transmit the electricity. The biggest challenge here is to transmit the electric power through long distances. You must have noticed that when you go outside of a city you can see overhead electricity lines. This is the platform for transmitting the electricity outside the cities. However, inside the cities, underground lines are more preferred due to the fact it is safer, but the underground cable are not usually used outside cities since it is much more expensive than overhead lines.
The final stage of the power supply to our homes will be distributing the electricity. When we transmit electricity, we have to step up the voltage to much higher values which help us to have less power loss during transmission. However when we are about to distribute the electricity to homes, we have to step that voltage down to the standard value and that is the final stage of the power systems and national grid.
A single shock of electricity can kill a person depending on the rate of current that will pass through the body of the human. The challenge of a power systems engineer here is make sure the power supply schematic was done safely and qualitatively. Well, it is not a secret that engineering is one of the toughest jobs nowadays, and when it comes to working on high voltages like this, a very responsible person has to take care of it all.
