Abstract: Thermal-mechanical fatigue assessment systems and methods include a controller operable to estimate a temperature of the conductor having a non-linear resistance based on an ambient temperature input and a current input for current flow through the conductor when connected to an energized electrical power system. A state of fatigue of the conductor may be assessed in view of an estimated first temperature differential between the conductor and an arc extinguishing medium surrounding the conductor, an estimated temperature differential between the temperature of the arc quenching medium and the ambient temperature, and the estimated temperature of the conductor.

Abstract: A compact fusible disconnect switch device includes a magnetic arc deflection assembly including pairs of magnets disposed about a mechanical switch contact assembly. The magnetic arc deflection assembly facilitates reliable connection and disconnection of DC circuitry operating at a voltage well above 125 VDC with reduced arcing intensity and duration. The pairs of magnets may apply magnetic fields in directions opposing one another to deflect electrical arcs in different directions at different locations in the mechanical switch contact assembly to facilitate high voltage DC switching operation.
