What are the functions of a Transformer?


A transformer is defined as a static device that changes the level of voltage between circuits. The transformer is basically a voltage control device that is used widely in the distribution and transmission of alternating current power.

  • The function of the transformer, as the name implies, is to transform alternating current energy from one voltage to another voltage.
  • When energy is transformed to a higher voltage the transformer is called a step-up transformer and energy is transformed to a low voltage the transformer is called a step-down transformer. If the power varies the current varies while the voltage remains fairly constant.

What are the operations carried by the transformer?

A transformer carries the below operations:

  1. Transfer of electrical energy from circuit to another
  2. Transfer of electrical power through electromagnetic induction
  3. Electric power transfer without any change in frequency
  4. Two circuits are linked with mutual induction.
