Introduction to Isolation Transformers

Isolation transformers are electrical devices that transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. They have a primary winding and a secondary winding that are magnetically coupled but electrically isolated from each other. This isolation helps in reducing electrical noise, providing protection against electrical shock, and preventing interference between different parts of an electrical system. Isolation transformers are widely used in various industries such as medical equipment, telecommunications, industrial automation, and power distribution.
