Numerical method for pre-arcing times : application in HBC fuses with heavy fault-currents
Résumé
This work deals with calculations of pre-arcing time prediction for fuse links used in industrial protection circuits in case of heavy faults-currents. An enthalpy method to solve heat-transfer equation included two phase-changes is presented. The mathematical model couples thermal and electrical equations based on the principle of energy conservation and the Ohm's law respectivity.
