Power Generation Stage:After power plants generate electrical energy using generators, step-up transformers are employed to increase the voltage. This facilitates the more efficient long-distance transmission of electricity via transmission lines, thereby minimizing energy losses during the transmission process. For instance, the electricity generated by large-scale thermal, hydroelectric, and wind power plants must all undergo processing by step-up transformers.
Power Transmission Stage: Transformers are also frequently required to perform voltage conversions between transmission lines of different voltage levels.
Power Utilization Stage:Step-down transformers progressively reduce high voltages to levels suitable for various types of consumers-such as the common 220V for residential use and 380V for industrial use-thereby ensuring a safe and stable supply of electricity.
