[Prior Art] In a power system, a transformer is an important device for power transmission and conversion. In other words, a transformer is a power device that transfers energy from one circuit to another through electromagnetic coupling without requiring relative movement of its own components. The main purpose of the transformer is to change the voltage, change the impedance, and separate the circuit. In the power transportation, the transformer plays a very important role. The transformer can convert the electric energy into a high voltage and low current form, and then convert it back, thus greatly reducing The loss of electrical energy during transport allows the electrical energy to be transported to a greater distance. The transformer structure is mainly composed of a main coil, an insulating material and a core for supplying a magnetic circuit; and the transformer core is mostly formed by stacking thin tantalum steel sheets for reducing loss (iron loss) and noise. Since the transformer is a large and fixed device, it must be strictly checked for the quality of the transformer. The traditional transformer process is very complicated, and the magnetic properties of the core must be tested under various conditions to obtain the best electromagnetic characteristics.
