Power Transformer

A power transformer is a type of electrical transformer that is used to step up or step down the voltage of an alternating current (AC) power supply. It consists of two or more windings (coils of wire) that are wound around a core made of ferromagnetic material, such as iron or steel. The primary winding is connected to the AC power supply, while the secondary winding is connected to the load. When the AC voltage is applied to the primary winding, it creates a magnetic field that induces a voltage in the secondary winding, providing a stepped-up or stepped-down AC voltage to the load. Power transformers are commonly used in a variety of applications, including power distribution systems, power supply units, and electric motors. They are essential for the safe and efficient transmission of electrical energy, as they allow for the step-up or step-down of voltage levels to match the requirements of the load. Additionally, power transformers are designed to be highly efficient and reliable, with a long lifespan.
