4. Flux-compensated current sensor
Principle
This type of current transducer operates in a closed loop. The principle is shown in figure 11 . The current to be measured I generates a flux in the magnetic circuit. It is compensated by the current i 2 from the amplifier to permanently cancel the ampere-turns :
The induction sensor detects induction in the air gap. The flux controller, whose reference setpoint is zero, generates the ampere-turns required...
