The substations also help to regulate and control the flow of electricity through the power distribution system. This is accomplished using various components such as switchgear, circuit breakers, and protective relays, which help to protect the equipment and ensure uninterrupted power supply.
Substations also serve as a hub for the power distribution system, allowing for the connection of multiple power sources and distribution lines. This helps to ensure that power is delivered efficiently and reliably to homes, businesses, and other facilities.
Substations also play an important role in reducing power outages and other disruptions to the power grid. They are equipped with advanced monitoring and control systems, which allow for real-time monitoring of the power distribution system and early detection of potential issues. This helps to ensure that any problems are addressed quickly, before they can lead to a larger outage.

Applications

Substations are used in a wide range of applications, from residential neighborhoods to large industrial facilities. They are a critical component of the power grid and play a key role in ensuring the reliable delivery of electrical power.
Substations are particularly important in urban areas, where space is often at a premium. They can be installed in areas such as city streets, parks, and other public spaces without causing significant disruption to the surrounding environment.
Substations are also used in a variety of other applications, including renewable energy systems, transportation infrastructure, and industrial facilities. In renewable energy systems, substations are used to connect wind turbines, solar panels, and other renewable energy sources to the power grid. In transportation infrastructure, substations are used to power electric trains, trams, and other forms of public transportation.
Substations are also increasingly being used in data centers and other large facilities that require a reliable source of electrical power. These facilities often require large amounts of power, and substations can help to ensure that the power is delivered efficiently and reliably.
Finally, substations are an important part of the ongoing transition towards more sustainable and environmentally-friendly energy systems. They are often equipped with features such as energy-efficient transformers, renewable energy sources, and advanced monitoring systems that help to reduce energy consumption and minimize environmental impact.
