What is an electrical transformer?
An electrical transformer is a device that transfers electrical energy between two or more circuits by electromagnetic induction. It consists of primary and secondary windings (coils) wound around a magnetic core. By varying the number of turns in the primary and secondary coils, the transformer can change the voltage levels of the electrical power flowing through it while maintaining the same power level.
A transformer is used to change the voltage of alternating current (AC) in electrical systems. It can increase (increase) or decrease (decrease) voltage levels to accommodate different stages of power transmission and distribution. For example, transformers are used to increase voltage for efficient transmission over long distances and to decrease voltage to safe levels for domestic or commercial use.
What is a transformer used for?
Simply put, a transformer works by using electromagnetic induction to transfer energy between its coils. An alternating current flowing through the primary coil creates a varying magnetic field around the core. This magnetic field induces a voltage in the secondary coil, which can be higher or lower than the voltage in the primary coil, depending on the ratio of the number of turns in the coils.
In a power plant, a transformer plays a vital role in adjusting the voltage levels between the different stages of electricity production and distribution. High voltage transformers increase the voltage generated by the installation to high levels suitable for transmission over long distances with minimal losses. On the distribution side, other transformers step down voltage to safer, usable levels for homes, businesses, and industrial facilities.
There are several types of transformers, including:
Power transformers: used in high voltage transmission networks to increase or decrease voltage levels.
Distribution transformers: located in low-voltage distribution networks to provide electrical energy to end users.
How does a transformer work simple explanation?
Isolation Transformers: Provide electrical isolation between circuits to improve safety and reduce electrical noise.
Instrument transformers: Include current transformers (CTs) and voltage transformers (VTs) used for measurement and protection in electrical systems.
Autotransformers: Have a single winding that serves as both primary and secondary, often used for voltage regulation and in specific applications where variable voltage is required.
