Ac Current Transducer

Any type of AC current transducer has a tube around which three solenoidal, or three-dimensional, coils are placed from one end to the other.

Any type of AC current transducer has a tube around which three solenoidal, or three-dimensional, coils are placed from one end to the other. The coil at the center is called the primary while the coils on both sides are called the secondaries. Along the tube’s axis slides a magnetic core.

Inducing the Current

The primary consists of a thick wire wound in a small number of turns. It is serially connected to the conductor which bears the current. The secondaries, on the other hand, are made of fine wires with a large number of turns.

What induces a voltage in each secondary coil is the alternating current that is directed through the primary coil. This amount of voltage is relative to each secondary’s reciprocal inductance with the primary. The frequency typically ranges from 1 to 10 kilohertz.
