Background

Three-phase dry-type transformers are the main components of various power supplies and electrical equipment. The device changes an alternating voltage by using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil and an iron core (magnetic core). In electrical equipment and wireless circuits, the high-voltage power supply is commonly used for voltage lifting, impedance matching, safety isolation and the like. In a generator, an electric potential is induced in a coil, whether the coil is moved through a magnetic field or the magnetic field is moved through a stationary coil, in both cases the value of the flux is constant, but the amount of flux linked to the coil varies, which is the principle of mutual induction. A transformer is a device for transforming voltage, current and impedance by using mutual electromagnetic induction.
