Isolation Transformers

An isolation transformer is a transformer used to transfer electrical energy from an AC source to an equipment or device while isolating the powered device from the power source, usually for safety reasons.

Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in sensitive equipment or to transfer energy between two circuits that must not be connected.

It is often built with special insulation between primary and secondary and is specified to withstand high voltage between windings.
