Transformers

WHAT IS A TRANSFORMER?

Transformers are electric devices that transfer electrical energy between two or more circuits through electromagnetic induction. Their primary function is to change the voltage level of alternative current (AC) without altering the frequency. They work by using two sets of wire coils wound around a magnetic core.

COMMON USES FOR TRANSFORMERS

• Transformers are essential in power grids to step up voltage for efficient long distance transmission and then step it down for safe use in homes and businesses.
• Many electronic devices, such as chargers, televisions, and computers, utilise small transformer to convert the high voltage from wall outlets into the lower voltages needed by those devices.
• Transformers are used to provide the necessary voltages for operating heavy machinery and equipment in factories.
• Isolation transformers provide electrical isolation between two circuits to protect equipment and improve safety in medical devices, electronics, and laboratories.
• Transformers are used in stabilising voltage in electrical systems by adjusting voltage fluctuations and ensuring consistent power.

ADVANTAGES OF TRANSFORMERS

Transformers are highly efficient at transmitting electrical energy, especially over long distances. They allow electrical power to be easily adjusted to meeting the needs of different systems, equipment, and regions. And finally, by lowering voltages for end use, transformers help prevent electrical shocks and damage to appliances.
