A substation is a critical component of the electrical grid, responsible for transforming voltage levels, managing power flow, and ensuring safe and reliable delivery of electricity from generation sources to end users. Substations are equipped with transformers, switchgear, circuit breakers, protective relays, and monitoring systems that collectively enable efficient power transmission and distribution.
Substations can be classified into several types—transmission, distribution, collector, and converter substations—based on their role in the energy supply chain. With the rise of renewable energy, renewable integration substations are gaining importance as they manage fluctuating inputs from wind, solar, and other clean energy sources.
