A substation is a crucial part of the electrical power system that transforms voltage levels to ensure efficient electricity distribution. It connects high-voltage transmission lines to lower-voltage distribution networks, making electricity safe for homes and businesses. Substations contain various equipment, including transformers, circuit breakers, and switches, which help manage the flow of electricity. Substations also play a vital role in maintaining the reliability of the power supply. They monitor and control the electrical grid, helping to prevent outages and manage demand. By regulating voltage and ensuring proper distribution, substations support the overall stability of the electricity network.
