Abstract
A processor receives an indication of a fault from a first isolation device. The processor sends a first open command to a downstream isolation device downstream of the fault, identifies a tie-in isolation device, and identifies a line section without current monitoring positioned between the tie-in isolation device and the downstream isolation device. The line section has a plurality of line segments, each having a load rating. The processor receives incoming and exiting current measurements for the line section and estimates a first current load for each of the line segments in the line section based on the incoming and exiting current measurements and the load ratings. The processor selects an intermediate isolation device between the tie-in isolation device and the downstream isolation device based on the first current loads, sends a second open command to the intermediate isolation device, and sends a close command to the tie-in isolation device.
