Current transformer - Wikipedia current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers.Instrument transformers scale the large values of voltage or current to small, …
