A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). The main functions include voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combination transformers, dry transformers, oil immersed transformers, single-phase transformers, furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box type transformer test transformers, etc Corner transformers, high current transformers, excitation transformers, etc. Transformers are the basic equipment for power transmission and distribution, widely used in industries, agriculture, transportation, urban communities, and other fields. There are approximately 17 million transformers operating on the grid in China, with a total capacity of approximately 11 billion kilovolt amperes. Transformer losses account for approximately 40% of power transmission and distribution losses, and have significant energy-saving potential. In order to accelerate the promotion and application of high-efficiency energy-saving transformers, improve energy resource utilization efficiency, and promote green, low-carbon, and high-quality development, in January 2021, the Ministry of Industry and Information Technology, the State Administration of Market Regulation, and the National Energy Administration jointly formulated the "Transformer Energy Efficiency Improvement Plan (2021-2023)"
