WebThe current transformer works to transform or change the magnitude of AC (50…400 Hz) in a system, typically from a higher current value to a lower current value. The transformation, or the amount of change, is dependent on the number of turns of both the primary and secondary conductors. WebElectric transformers are static electrical machines that transform electric power from one circuit to the other without changing the frequency. An electrical transformer can increase or decrease the voltage with a corresponding increase or decrease in electric current.

WebDec 1, 2016 · Transformers have two sides, a high-voltage side and a low-voltage side. In normal operation, electricity flows into the transformer on the high-voltage side where it goes into a coil of wire, usually wound around an iron core. As the electricity flows through this coil, it creates a magnetic field that “induces” a voltage in the other coil.

WebApr 4, 2024 · Transformers are employed for widely varying purposes; e.g., to reduce the voltage of conventional power circuits to operate low-voltage devices, such as doorbells and toy electric trains, and to raise the voltage from electric generators so that electric power can be transmitted over long distances.
