Transformers are used primarily for the purpose of converting alternating current (AC) electricity from one voltage level to another. They serve two main functions:-
Voltage Transformation: Transformers can step up or step down the voltage of AC electricity. Step-up transformers increase voltage from a lower level to a higher level, typically used in power transmission to reduce energy loss over long distances. Step-down transformers decrease voltage from a higher level to a lower level, making electricity safe and usable for residential, commercial, and industrial applications.
Isolation: Transformers also provide electrical isolation between the input (primary) and output (secondary) sides. This isolation protects sensitive equipment and devices from electrical disturbances, such as voltage spikes and ground loops, and ensures safety for users and operators.
Overall, transformers play a crucial role in electrical power generation, transmission, distribution, and utilization across various industries and applications.
