Background
The transformer is a device for changing alternating voltage by using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil and an iron core. The main functions are as follows: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, and the like. According to the application, the method can be divided into: power transformers and special transformers. The circuit symbol is usually T as the beginning of the number, for example T01, T201, etc., and an on-load tap changing transformer is a static electrical device which is used to change an AC voltage of a certain value into one or several voltages of the same frequency and different values. When the primary winding passes through the alternating current, an alternating magnetic flux is generated, and the alternating magnetic flux conducts magnetism through the iron core, so that alternating electromotive force is induced in the secondary winding. The level of the secondary induced electromotive force is related to the number of turns of the primary winding, i.e. the voltage is proportional to the number of turns. The main role is to transmit electrical energy, and thus, the rated capacity is its main parameter. The rated capacity is a conventional value for the power delivered, which characterizes the amount of electrical energy transmitted, expressed in kVA or MVA, and is used to determine the rated current which does not exceed the temperature rise limit under defined conditions when a rated voltage is applied to the transformer.
