Evolving fault
An evolving fault starts as a single-phase fault which leads to single-pole tripping and then the
fault spreads to another phase. The second fault is then cleared by three-pole tripping.
The auto recloser will first receive a start signal (
The auto recloser will start a single-phase auto reclosing sequence, if programmed to do so. At the
evolving fault clearance there will be a new
The single-phase auto reclosing sequence will then be stopped, and instead the timer,
three-pole auto reclosing will be started from zero. The sequence will continue as a three-pole
auto reclosing sequence, if it is a selected alternative reclosing mode. The second fault which can
be single-phase is tripped three-pole because the trip function (SMPPTRC) in the IED has an
evolving fault timer which ensures that second fault is always tripped three-pole. For other types
