Behaviour of a DC zero-flux current sensor: magnetic field analysis and comparison with experimental results

The magnetic section of the finite-element ANSYS code, in particular its optimization feature, has been used to predict the behavior of a zero-flux current sensor, briefly described, which is intended to be used in a fusion experiment to measure pulsed currents up to 50 kA, over a bandwidth from DC...

Description
Summary:The magnetic section of the finite-element ANSYS code, in particular its optimization feature, has been used to predict the behavior of a zero-flux current sensor, briefly described, which is intended to be used in a fusion experiment to measure pulsed currents up to 50 kA, over a bandwidth from DC to 10 kHz. The computed results fit well with those coming from experimental tests performed on a prototype.< >
