AR FORCE THREE-PHASE TRIP LOGIC

Following single-phase tripping, while the Autoreclose cycle is in progress, and upon resetting of the protection
elements, tripping switches to three-phase.
Any protection operations that occur for subsequent faults while the Autoreclose cycle remains in progress will be
tripped three-phase.
