How does the power transformer work?

A power transformer works on the principle of electromagnetic induction. It consists of two or more coils, called windings, wound around a common core. When alternating current (AC) flows through the primary winding, it generates a varying magnetic field in the core. This varying magnetic field induces a voltage in the secondary winding by electromagnetic induction. The ratio between the number of turns in the primary and secondary windings determines whether the transformer increases or decreases the voltage.

The operating principle of a power transformer is based on Faraday’s law of electromagnetic induction. When an AC voltage is applied to the primary winding, it creates a magnetic field that fluctuates with the AC frequency. This magnetic field passes through the core and induces a voltage in the secondary winding. The voltage induced in the secondary winding is proportional to the turns ratio between the primary and secondary windings, thus allowing voltage conversion.

What is the working principle of a power transformer?

A voltage transformer, also called a potential transformer, functions similarly to a power transformer, but is specifically designed to measure or step down high voltages to lower, manageable levels for metering or protection purposes. It uses the principle of electromagnetic induction to reduce high voltage to a lower voltage that can be safely measured or used for control systems.

How does a voltage transformer work?

The function of a power transformer is to transfer electrical energy between two or more circuits by electromagnetic induction. It is used to increase (raise) or decrease (lower) voltage levels to meet the requirements of different parts of an electrical system. Power transformers are essential in electrical distribution networks to ensure that electrical energy is transmitted efficiently over long distances and used efficiently at different voltage levels.

A power transformer does not work if supplied with direct voltage (DC), because it relies on alternating current (AC) to produce a varying magnetic field necessary for electromagnetic induction. The DC voltage does not vary and therefore does not create the fluctuating magnetic field necessary to induce a voltage in the secondary winding. Without this alternating magnetic field, the transformer cannot operate and will not transfer power between its windings.
