How Do Substations Work?
In many ways, the grid is a one-size-fits-all system - a gigantic machine to which we all connect spinning in perfect synchrony across, in some cases, an entire continent. On the other hand, our electricity needs, including when we need it, how much we need, and how reliably it should be delivered vary widely. Substations play a critical role in controlling and protecting the power grid.
An electrical substation is a critical component of an electric power grid, as it facilitates the transfer of electricity from generators to end-users. These substations are typically equipped with a transformer, circuit breaker, and components such as a current transformer (CT), potential transformer (PT), disconnector, and surge arrester. All these devices have specific roles to play in efficiently transmitting electricity from the power station to users.
A transformer is responsible for increasing or decreasing the voltage levels of electricity flowing through the grid; This helps reduce losses during transmission over long distances by allowing higher voltage lines to be used instead of lower ones. A circuit breaker helps protect lines and equipment in case of sudden high current surges/short circuits that may damage equipment or even cause fires. CTs and PTs are used for measuring parameters like voltage, current, power factor etc.
