what is a isolation transformer?

An isolation transformer is a type of transformer designed to isolate electrical devices from the power source, providing safety and reducing electrical noise. It typically has a 1:1 turns ratio, meaning the input and output voltages are the same. By isolating the load from the supply, it protects against electric shock, minimizes ground loops, and enhances equipment performance. Isolation transformers are commonly used in medical equipment, audio systems, and sensitive electronic devices.
