Abstract
In an example embodiment, systems and methods for detecting and handling faults in a DC bus system (“system”) can comprise detecting a fault in the segment, isolating the segment from the system, waiting for a period of time, connecting a probe power unit to the system at the isolated segment, and determining if a fault still exists on the isolated segment, wherein the determining is based on whether power is discharging from the probe power unit when connected to the system. The system can comprise one or more controllers and a probe power unit.
