Responder allows you to assign an incident to a specific phase. In the example below, only phase A is open on the recloser and only the A and AB phase transformers and load points are affected.

The prediction engine takes phase into account when rolling up incidents. If two out of three A-phase transformers have incidents, the prediction engine will roll the incident up to just the A phase (BC Closed) on the upstream three-phase recloser.
