Transformer

Definition

A transformer is a device that changes, or transforms, alternating current (AC) from one voltage to another.

Purpose

The purpose of a transformer is to convert electrical voltage levels to match the requirements of different parts of the power grid or specific applications, ensuring efficient power distribution and usage.

Examples of Use

1. Power Distribution: Transformers are used in power grids to step up the voltage for long-distance transmission and step down the voltage for local distribution.
2. Electronics: Small transformers in electronic devices convert the voltage to levels suitable for circuits and components.
3. Industrial Applications: Transformers in industrial settings provide the necessary voltage to heavy machinery and equipment.

Related Terms

• Step-Up Transformer: A transformer that increases voltage from the primary to the secondary winding.
• Step-Down Transformer: A transformer that decreases voltage from the primary to the secondary winding.
• Isolation Transformer: A transformer used to transfer electrical power while isolating the powered device from the power source.

Notes

• Efficiency: Transformers are designed to operate with high efficiency, minimizing energy loss during voltage conversion.
• Maintenance: Regular maintenance is necessary to ensure transformers operate safely and efficiently.
