What is a transformer?

     Transformer is a device that applied the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the usage, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols often use T as the beginning of the number. Example: T01, T201, etc.

Transformer is a very important tool in our daily production. Because the machines we use in our daily production are not necessarily the 220 volts we specified, at this time we need to use transformers to enable these machines to be used in our limited voltage.
