SYSTEM FOR PROTECTING A DC POWER DISTRIBUTION BUS DURING HOT SERVICING

摘要

A system for preventing voltage drops when a load circuit is connected and preventing arcing when a load is disconnected from an energized bus includes a current limit device and low impedance shunt 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.
