A Transformer is a device which UseS the principle of electromagnetic induction to change the alternating current voltage. The main functions are. voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization(magnetic saturation transformer). It can be divided into: power transformer and special transformer (furnace transformer, rectifier transformer. power frequency test transformer, voltage regulator, mine transformer, audio transformer, intermediate frequency transformer, high frequency transformer impact transformer, instrument transformer, electronic transformer, reactor, mutual transformer, etc. ) Circuit symbol T is often used as the beginning of a number Example: TO1, T201,etc.
