What is a Current Transformer?

A Current transformer, sometimes called CT, is used to monitor a power line current delivered to a load.

An AC current transformer is a special kind of transformer. Most current transformers do not have a primary coil. The conductor, whose current is to be measured, acts as the primary coil when it is placed inside the magnetic path of the core.

A current transformer converts the primary current of the conductor to a current output whose value depends on N2. The output current can be computed if N2 is known. If N2 is 1000 turns, the output current is 1/1000 of the primary current, which can be expressed as 1 Milliampere per Ampere. Such a current transformer has a turns-ratio of 1000:1. The output of this CT can be read by any AC ammeter whose input impedance is compatible with the specifications of the current transformer.
