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 is taken from pre-processor
blocks.
The sensitive directional ground fault protection has the following sub-functions
included:
Default Description
0.100 Time delay for non-directional residual
overvoltage
1.00 Residual release current for all directional
modes, in % of IBase
3.00 Residual release volt for all dir modes, % of
VBase
Default Description
1 Selection of one of the Global Base Value
