A power transformer is a static electrical device that is used to convert a certain value of AC voltage (current) into another or several different values ​​of voltage (current) with the same frequency.
    Stationary equipment with two or more windings, in order to transmit electrical energy, at the same frequency, by electromagnetic induction to convert the alternating voltage and current of one system into the voltage and current of another system, usually the values ​​of these currents and voltages are different of.
   A transformer is a piece of static electrical equipment used to transform AC voltage and current to transmit AC power. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers, and special-purpose transformers according to their uses: power transformers are necessary equipment for power transmission and distribution and power user distribution; test transformers are used to withstand voltage (boost) electrical equipment. Test equipment; instrument transformers are used for electrical measurement and relay protection of power distribution systems (PT, CT); special-purpose transformers include electric furnace transformers for smelting, welding transformers, rectifier transformers for electrolysis, and small voltage regulating transformers.
Power transformers are one of the main equipment in power plants and substations. The function of the transformer is multi-faceted. It can not only increase the voltage and send the electric energy to the electricity-consuming area but also reduce the voltage to the voltage used at all levels to meet the needs of electricity consumption. In short, both step-up and step-down must be completed by the transformer. In the process of transmitting electrical energy in the power system, two losses of voltage and power will inevitably occur. When the same power is transmitted, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage. Using a transformer to increase the voltage reduces transmission losses.
