The term, 'instrument transformer', is applied to current transformers and voltage transformers (known, in North America, as 'potential Transformers'). The primary windings of instrument Transformers are connected to high-voltage systems, and their secondary windings provide outputs to measuring instruments or protective relays. They also provide isolation from the high-voltage system for the purpose of safety.
