A system for preventing voltage drops when a load circuit (12) is connected and preventing arcing when a load is disconnected from an energized bus (14) includes a current limit device (26) and low impedance shunt (28) that bypasses the current limit device when activated. The system activates the low impedance shunt only after a load capacitance is charged when the load is connected and deactivates the low impedance shunt prior to disconnecting the load.
n système destiné à prévenir les chutes de tension quand une charge (12) est branchée au circuit, et pour prévenir la formation d'arcs lorsque la charge est débranchée d'un bus sous tension (14) comprend un limiteur de courant (26) et une dérivation à faible impédance (28) qui contourne le limiteur de courant lorsqu'il est sous tension. Le système active la dérivation à impédance seulement après le chargement d'une capacité de charge, lorsque la charge est branchée, et désactive la dérivation à faible impédance avant de débrancher la charge.
