Résumé

The aim of this paper is to simulate the performances of a ground fault circuit-breaker (GFCB) relay with new low nickel content alloys. Indeed, in the construction industry, the materials become more expensive as their nickel content increases. Moreover, the demand for nickel is particularly sensitive to the economic conjuncture. Therefore, an original electromagnetic relay model has been developed and validated in different working conditions (current amplitude, frequency, temperature). A dedicated magnetic characterization of materials is needed, using basically a usual and industrial GFCB relay for reference and design data in modeling. First, the magnetic model of the relay is built and checked against experimental data. The simulation may predict the tripping current threshold of the relay. On the other hand, new low nickel content alloys for relay parts are studied in this framework, thanks to the developed model. The effect of temperature on the magnetic properties of the candidate materials and the electrical performances of the virtual relays is presented. The results, analysis, and conclusions are given. Finally, a first attempt to predict the economic gain made with a change of material is made.
