ABSTRACT:
The current transformer comprises a magnetic circuit associated to a primary conductor and a secondary winding connected to a trip relay. The magnetic circuit comprises a mobile part and a fixed part. The mobile part goes from an open position to a closed position when a primary current flowing in the primary conductor exceeds a preset value. The change of position of the mobile part makes the magnetic flux in the magnetic circuit vary which induces a secondary current in the secondary winding to actuate the trip relay. Application, notably to trip devices and circuit breakers.
