What is a transformer and what are its uses in daily life?
A transformer is an electrical device that transfers electrical energy between two or more circuits by electromagnetic induction. In everyday life, transformers are used to adapt electrical voltages to various applications. For example, they are found in power adapters for electronic devices, where they convert high mains voltage to lower, safer levels suitable for devices such as laptops and phone chargers. Transformers also ensure that household appliances receive the correct voltage and are used in powering medical equipment, audio systems and other electronic devices.
A transformer is a device used to change the voltage level of alternating current (AC) in electrical circuits. Its areas of use include:
Power Transmission: To increase voltage for efficient long-distance transmission and reduce voltage for local distribution.
Electrical Distribution: To reduce voltage to safe levels for residential and commercial use.
Measurement and protection: Instrument transformers measure and monitor voltage and current in electrical systems.
Isolation: To electrically isolate different parts of a system for safety and noise reduction reasons.
Transformers come in several types, including:
Power transformers: used in high voltage transmission systems.
Distribution Transformers: Reduce voltage for local distribution.
Instrument transformers: For measurement and protection, including potential and current transformers.
Autotransformers: Provide variable voltage adjustments with a single winding.

Isolation transformers: Separate different parts of electrical systems for safety.
What is a transformer and what are its types?
Transformers are usually located at key points in electrical systems. Power transformers are typically found in substations where high voltage power is either increased for transmission or decreased for distribution. Distribution transformers are located in neighborhoods, often on utility poles or in ground-level enclosures, to provide final voltage reduction for residential and commercial use. Smaller transformers can be found in electronic devices and power adapters where voltage adjustment is required.
Distribution transformers are used to step down the high voltage of the electrical grid to safe, usable levels for homes and businesses. They are placed in various locations, including on utility poles, in underground vaults, or in dedicated transformer stations. These transformers ensure that electricity delivered to end users is at the appropriate voltage for residential and commercial appliances, helping to maintain safe and reliable power distribution.
