CGIS2517: How to Choose the Right Current Transformer for Your Needs

A current transformer is a device that is used to measure the current in an electrical circuit. It is made up of two coils of wire, one of which is wrapped around the other. The current that is flowing through the circuit is measured by the amount of magnetic flux that is created in the second coil.
