t-start Start timer - While 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 start time has an impact on
whether an AR attempt should be started
when the fault is far away or high
resistance.
