A current transformer (CT) is a type of transformer that is used to measure alternating current (AC).
It produces a current in its secondary which is proportional to the current in its primary.
As the name implies current transformers are generally used to step down current in a very predictable fashion with respect to current and phase. For example, you wish to measure the current being drawn by a motor to determine if the motor is lightly loaded or being overloaded. First, you must know the voltage level of the motor circuit. From this you can determine what voltage class insulation the current transformer should have.
We produce current transformers in Toroidal cores and Split core, in magnetic materials Nanocrystalline and grain oriented electrical steels.
