What is a current transformer?

A current transformer (CT) is mainly used to measure (AC) alternating electric current levels that need to be monitored when exceeding 50 ampere’s. The CT produces a 5 amp output for each secondary range. The current transformer (CT) provides additional isolation from the conductor.

Current transformers (CT) are also used for other functions in electronic equipment. Current transformers, together with voltage transformers (VTs) or potential transformers (PTs), are known as instrument transformers.
