An electrical transformer uses the conversion of an alternating current of one voltage to an alternating current of another voltage. Voltage transformers (from the Latin word “transform” – “transform”) are used in the AC network to increase or decrease the voltage. They can increase or decrease the input voltage, including changing the magnitude and frequency of the initial voltage.
The important role of transformers is precisely in performing the function of transformation, isolation, measurement and protection. In electrical engineering, you cannot do without transformers.
