A three-phase transformer is an electrical equipment whose main function is to convert one level of AC voltage into another level of AC voltage based on the principle of electromagnetic induction, in order to meet the needs of different loads. When AC current is passed through the primary coil of a transformer, AC magnetic flux is generated in the iron core (or magnetic core), causing voltage (or current) to be induced in the secondary coil. This device that transforms AC voltage, current, and impedance is an important component of the power system.
Three phase transformers have efficient and stable performance, which can ensure the stable operation of the power system. Through optimized design, three-phase transformers have lower iron and copper losses, resulting in less energy loss during the conversion process. In addition, three-phase transformers also have strong short-circuit resistance, low noise, easy maintenance, strong adaptability, strong scalability, and energy-saving and environmental protection characteristics. These functional features make three-phase transformers widely used in various aspects of the power system, such as power stations, power distribution, and industrial applications.
