Electromagnetic relay modelling: a multi physics problem. Part 1: Modelling of the geometry
Résumé
In order to ensure life safety, differential circuit breakers are employed. These devices are usually made of different parts. One of the part that will be described in this paper is the electromagnetic relay. This actuator must be modelled with a great accuracy in order to predict if the circuit breaker will open if an eventual fault occurs. In this paper, we focus on the modelling of the geometry of the electromagnetic relay and of its static behaviour. A tripping criterium and different optimization results of the model parameters will be discussed..
