A system for controlling a power distribution network providing power using a plurality of phases, the system comprising: an electronic processor; and memory storing instructions that, when executed by the electronic processor, cause the system to: receive a first fault indication associated with a fault in the power distribution network from a first isolation device of a plurality of isolation devices; identify a first subset of the plurality of phases associated with the first fault indication and a second subset of the plurality of phases not associated with the first fault indication, wherein the first subset and the second subset each include at least one member; identify an upstream isolation device upstream of the fault; identify a downstream isolation device downstream of the fault; send an open command to the downstream isolation device for each phase in the first subset only; and responsive to the first isolation device not being the upstream isolation device, send a close command to the first isolation device for each phase in the first subset; and not send a close command to the first isolation device for each phase in the first subset when the first isolation device is the upstream isolation device. an electronic processor; and memory storing instructions that, when executed by the electronic processor, cause the system to: receive a first fault indication associated with a fault in the power distribution network from a first isolation device of a plurality of isolation devices; identify a first subset of the plurality of phases associated with the first fault indication and a second subset of the plurality of phases not associated with the first fault indication, wherein the first subset and the second subset each include at least one member; identify an upstream isolation device upstream of the fault; identify a downstream isolation device downstream of the fault; send an open command to the downstream isolation device for each phase in the first subset only; and responsive to the first isolation device not being the upstream isolation device, send a close command to the first isolation device for each phase in the first subset; and not send a close command to the first isolation device for each phase in the first subset when the first isolation device is the upstream isolation device. receive a first fault indication associated with a fault in the power distribution network from a first isolation device of a plurality of isolation devices; identify a first subset of the plurality of phases associated with the first fault indication and a second subset of the plurality of phases not associated with the first fault indication, wherein the first subset and the second subset each include at least one member; identify an upstream isolation device upstream of the fault; identify a downstream isolation device downstream of the fault; send an open command to the downstream isolation device for each phase in the first subset only; and responsive to the first isolation device not being the upstream isolation device, send a close command to the first isolation device for each phase in the first subset; and not send a close command to the first isolation device for each phase in the first subset when the first isolation device is the upstream isolation device.
