An isolation transformer is a type of transformer that is designed to provide electrical isolation between the input and output circuits. It works by using a primary and secondary winding that are electrically isolated from each other, often with a shield or barrier between them.
Isolation transformers are used for a variety of purposes, including:
- Electrical safety: Isolation transformers are commonly used in situations where there is a risk of electrical shock or damage to sensitive equipment. By isolating the input and output circuits, the transformer helps to prevent electrical noise, surges, and other electrical issues from causing damage or harm.
- Signal transmission: Isolation transformers are also used to transmit signals between different circuits without introducing electrical interference. This is particularly important in applications such as audio or video transmission, where interference can cause distortion or other quality issues.
- Grounding: Isolation transformers can also be used to provide a separate grounding reference for different circuits. This is useful in situations where different parts of a system have different ground potentials, which can cause electrical interference or other issues.
Isolation transformers can be found in a wide range of applications, including power supplies, audio systems, and medical equipment. They are often used in combination with other types of transformers or electrical components to provide specific functionality or improve performance.
