A substation is a crucial part of the electrical power system. It helps to transform high-voltage electricity from power plants into lower voltages suitable for homes and businesses. By doing this, substations ensure that electricity can be safely distributed through power lines to reach consumers. Inside a substation, you'll find various equipment like transformers, circuit breakers, and switches. These components work together to manage the flow of electricity and protect the system from faults. Without substations, it would be challenging to deliver reliable power to our everyday lives, making them essential for our modern society.
