1)
It is recommended to set the I< threshold to a value that is sligthly below the fault current that is expectable.
By means of that it is possible to shorten the BF supervision timer and hence reduce thermal and mechanical damage
of the electrical equipment in case of a Breaker Failure. The lower the threshold, the longer the time that is needed to
detect, that the breaker is in the open position, especially if there are transients/harmonics.
Note: Tripping delay of the
BF module = Minimum delay time (tripping time) of the backup protection!
