A transformer is a device that uses the principle of electromagnetic induction to change the voltage of alternating current. Its main components are the primary coil, secondary coil, and core (magnetic core). Its main functions include: voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer), among others.

The high-voltage chamber of the European-style box transformer is generally composed of high-voltage load switches, high-voltage fuses, and surge protectors, allowing for power on/off operations and providing overload and short-circuit protection. The low-voltage chamber consists of low-voltage air switches, current transformers, ammeters, voltmeters, etc. The transformer is usually of the S9 type or dry type.
Due to the large electricity consumption in the United States and the lack of high-voltage metering methods, imported products generally do not have high-voltage metering, and various instruments and distribution circuit breakers are not set up within the low-voltage interval. Imported products are often operated by agents, who typically do not have the capability for production or modification. To meet the extremely simple usage requirements of users, it is necessary to outsource the production of low-voltage distribution devices to switch manufacturers. Due to the limited available space, only four circuits of low-voltage metering can be configured. High-voltage metering, low-voltage compensation, and multi-circuit distribution cannot be achieved in the product itself.
