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