A transformer is a piece of electrical equipment which changes a voltage to a higher or lower voltage.
transformer in British English
(trænsˈfɔːmə)
noun
1.
a device that transfers an alternating current from one circuit to one or more other circuits, usually with an increase (step-up transformer) or decrease (step-down transformer) of voltage. The input current is fed to a primary winding, the output being taken from a secondary winding or windings inductively linked to the primary
2.
a person or thing that transforms
transformer in American English
(trænsˈfɔrmər)
noun
1.
a person or thing that transforms
2. Electricity
a device containing no moving parts and consisting essentially of two or more coils of insulated wire that transfers alternating-current energy by electromagnetic induction from one winding to another at the same frequency but usually with changed voltage and current values

A current transformer is a transformer that is designed to give an accurate current ratio for the purpose of measurement and control.
isolation transformer
An isolation transformer is a transformer with physically separate primary and secondary windings , that prevent it from transferring unwanted noise from the input circuit to the output windings.
