the start timer runs
down, an AR attempt
can be started. Only
if the trip command
is given within the
start time/duration an
AR attempt could be
started. The location
and the resistance of
the fault have a big
influence on the
tripping time. The

impact on whether
an AR attempt
should be started
when the fault is far
away or high
resistance.
