Frequently Asked Questions (FAQs)

An Isolation Transformer is a transformer that protects circuits, equipment, and people from shocks and short circuits as well as helps make accurate measurements by providing electrical isolation. By isolation we mean galvanic isolation, that is, there is no direct conduction path or physical connection for the current to flow. The Isolation Transformer uses magnetic flux to transfer power and signals across the separated circuits.


Unlike regular transformers, the main purpose of Isolation Transformers is to provide galvanic isolation in the electrical system. Although they can work as step-up or step-down transformers, they often have a 1:1 turns ratio. This means that the number of turns on the primary and secondary windings in an Isolation Transformer are equal and the primary and secondary voltage values are equal.
