Transformers are fundamental components of electrical power systems, playing a crucial role in the transmission, distribution, and utilization of electrical energy. They operate on the principle of electromagnetic induction, efficiently transferring electrical power between circuits at different voltage levels. This article provides a comprehensive overview of transformers, covering their types, operating principles, applications, and key considerations for electrical engineers. Operating Principles: Transformers consist of two or more coils of wire wound around a common ferromagnetic core. When an alternating current flows through the primary winding, it generates a fluctuating magnetic flux in the core. This flux links with the secondary winding, inducing an electromotive force (EMF) according to Faraday's law of electromagnetic induction. The voltage transformation ratio is directly proportional to the turns ratio of the windings: V₁ / V₂ = N₁ / N₂ Where: V₁ = Primary volta...
