Logic of the Non-Directional Intermittent Ground-Fault Protection
Measured Value 3I0
The intermittent ground-fault current 3I0 can either be measured via the standard ground-current input IN or
via the sensitive ground-current input I
NS
. It can also be calculated from the sum of the 3-phase currents. The
current value and its setting range depend on the parameter Connection type of the measuring point I-3ph.
