Function inputs
SEMOD171963-4 v5
The function is using phasors of the residual current and voltage. Group signals I3P
and V3P containing phasors of residual current and voltage which are taken from pre-
processor blocks.
The sensitive directional ground fault protection has the following sub-functions
included:
