Isolation Transformer

Isolation transformers block transmission of the DC component in signals from one circuit to the other but allow AC components in signals to pass Transformers that have a ratio of 1 to 1 between the primary and secondary windings are often used to protect secondary circuits and individuals from electrical shocks between energized conductors and earth ground.
