Transformers
An electrical transformer is a fundamental device in power distribution systems that efficiently transfers electrical energy between circuits. Operating on the principle of electromagnetic induction, a transformer consists of two coils—primary and secondary—linked by a magnetic core. When an alternating current (AC) flows through the primary coil, it produces a magnetic field in the core. This magnetic field, in turn, induces a voltage in the secondary coil through electromagnetic induction. The transformation ratio between the primary and secondary voltages is determined by the turns ratio of the coils.
Transformers serve two primary functions in electrical systems: stepping up voltage for long-distance power transmission to minimize energy loss, or stepping down voltage for safe distribution and utilization in homes and businesses. By facilitating the efficient transmission of electrical power, transformers play a crucial role in ensuring a reliable and stable supply of electricity across diverse applications.
