Fault Isolation Device


The purpose of the Fault Isolation Device (FID) project is to develop a device that minimizes the time needed to isolate and clear faults in the FREEDM system as part of the system’s intelligent fault management functionality. Due to the current-limiting nature of the FREEDM system, grid voltage will decrease quickly in the event of a fault; this makes ultra-fast fault isolation a necessity. In addition, research related to the FID will significantly impact DC grids, which are also reliant on ultra-fast protection.
