An isolation transformer is a type of transformer that is designed to provide electrical isolation between the input and output of the transformer. This is achieved by separating the primary and secondary windings of the transformer, which are wound on separate bobbins and are not electrically connected.
The primary winding of the transformer is connected to the input voltage source, while the secondary winding is connected to the load. The isolation transformer provides isolation between the two circuits, which can help to protect the equipment and personnel from electric shock, ground loops, and electromagnetic interference.
Isolation transformers are commonly used in electronic equipment, such as audio equipment, computers, and medical equipment, where electrical isolation is important for safety and performance reasons. They are also used in power distribution systems to help isolate sensitive equipment from electrical noise and transients.
