Numerical Simulation of Power-grid Overloads and Short-circuit Protections
Résumé
Spurious electromagnetic emanations can propagate along the power-grid cable network of critical infrastructures, which poses unacceptable risks for their security and safety. According to international standards, protective devices have to be inserted in low-voltage distribution networks in order to prevent physical damages due to either overload or short-circuit. We propose here to characterize these devices by measuring their scattering parameters in order to estimate their effects on the conducted propagation of electromagnetic interference.
