Structure/Embedding of the Directional Function in Protection Function Groups
Non-Directional Sensitive Ground-Fault Detection
The Non-directional sensitive ground-fault detection function can be used in protection function groups
that only make the zero-sequence system (3I0) available. The function comes factory-set with a non-direc-
tional 3I0> stage.
The following stages can be operated simultaneously within the function:
•
4 non-directional 3I0> stages
•
2 non-directional Y0> stages
•
2 non-directional pulse-pattern detection stages
The general functionality works across stages on the function level.
The group-indications output logic generates the following group indications of the entire function by the
logical OR from the stage-selective indications:
•
Pickup
•
