How Does a Current Transformer Work?

A current transformer consists of a primary winding, secondary winding, and a magnetic core. The primary winding, connected in series with the circuit, carries the full load current, while the secondary winding produces a reduced current proportional to the primary current.

The current transformer works on the principle of electromagnetic induction. The primary winding generates a magnetic field in the core, inducing a current in the secondary winding. This induced current is proportional to the primary current and can be safely measured and analyzed.

Applications and Benefits of Current Transformers Current transformers are used in power distribution systems for measurement and protection.

Current transformers come in various types, including wound, toroidal, and bar types. Wound CTs have separate primary and secondary windings, toroidal CTs have no primary winding and rely on the conductor passing through a core, and bar CTs use a bar as the primary winding.
