8.3.7 Operation principle
8.3.7.1 Function inputs
The function is using phasors of the residual current and voltage. Group signals I3P
and U3P containing phasors of residual current and voltage is taken from pre-
processor blocks.
The sensitive directional earth fault protection has the following sub-functions
included:
