Calorimetric measurement and modeling of iron losses in a Silicon Iron current sensor

Résumé

The magnetic losses of a supply current sensor dedicated to circuit breakers are investigated. Measurements were performed using a precision calorimeter. Several frequencies and voltages were tested. A model of the sensor’s core material (NO FeSi sheet M250-50A) was built with the Loss Surface (LS) dynamic hysteresis model and implemented in a 3D FEM computation tool. The sensor was simulated and iron losses were computed. Comparison between experiments and simulation shows a high concordance that leads to conclude about the reliability of the LS model.
