Operation principle
Function inputs
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:
Directional residual current protection measuring 3I
φ is defined as the angle between the residual current 3I
φ=ang(3I )-ang(V )|). The reference voltage (Vref) is the polarizing quantity which is
0 ref
