Electricity Substations: What They Are and How They Work

What are Substations?

Substations play a crucial role in the electrical power system. They are used to regulate and control the voltage of electricity, making it safe to transfer into homes and businesses. Substations can also transform voltage from low-to-high or vice versa, depending on the needs of the electrical system.

There are three main types of substations: transmission, sub-transmission, and distribution substations. The size of the substation depends on its usage, whether it caters to residential or industrial properties. However, some facilities such as schools and hospitals may require their own substation.

When it comes to businesses and organisations that require a substation, it is important to enlist the services of a company, like Business Electric, that understands all aspects of substations.

The following table summarizes the key features of the three main types of substations:

Substations are essential components of the electrical power system. They help regulate and control the voltage of electricity, making it safe to transfer into homes and businesses. Choosing the right type of substation for your needs and enlisting the services of an expert company will ensure a reliable and efficient electrical system.
