The Working Principle of Electrical Power Transformers

1. The use of electrical power transformers

When the electrical power transformer is working in the system, it can  transfer the electric energy from its primary side to the secondary side through the conversion of electromagnetic energy, and the voltage can be increased or decreased according to the needs of electrical transmission and distribution.Therefore, it plays a very important role in the whole process of the production, transmission and distribution of electric energy. In the whole power system, the capacity of the transformer is usually three times more than that of generator. The function of the electrical power transformer is various:it not only can raise the voltage to send the electric energy to the electricity-consumption area, but also can reduce the voltage to all levels of service voltage to meet the needs of electricity.

2. The working principle of electrical power transformers

The operation of all types of electrical power transformers is based on the principle of electromagnetic induction. The main body of it is composed of winding and iron core.While working, the winding is the "electrical" path, and the iron core is the "magnetic" path, which also plays the role of the skeleton of the winding. After electric energy is inputted on the primary side, an alternating magnetic field (i.e. from electric energy to magnetic field) is generated in the iron core due to its alternating change.Because of the chains of turns (penetrate), the magnetic field lines of the secondary winding are constantly changing alternately, so that the secondary electromotive force is induced. When the external circuit is linked up, the induced current is generated, which outputs electrical energy (that is, from magnetic field energy to electrical energy). This "electric-magnetic-electric" conversion process is based on the principle of electromagnetic induction, and this energy conversion process is also the working process of the electrical power transformer.
