displayed at the end of the fault. If several protection functions detect a fault
then the criterion is selected on the basis of the priorities given in the table
below. The selected criterion is displayed at the P631.
Priority
Function Recognizing the Fault
Acquisition Time Criterion
1
Differential protection function
Maximum differential current
2
Definite-time overcurrent protection or inverse-time
overcurrent protection
Maximum restraining current
3
Functions according to the selection through m out of n
parameters
End of fault
The difference in time between the start of the fault and the fault data
acquisition time is determined by the P631 and displayed.
