spective measuring location or side (in case of earth faults, below the smallest fault
current). This parameter can only be altered in DIGSI at Additional Settings.
In address 8403 FUSE FAIL MON. the fuse-failure monitor, in case of asymmetrical
tests, for example can be switched off.
Three-phase Mea-
sured Voltage
Failure (Fuse-
failure Monitor)
At address 8426 FFM U<max (3ph) the minimum voltage is set. If the measured
voltage drops below this threshold and a simultaneous current jump is not detected
while all three-phase currents are greater than the minimum current required for the
impedance measurement by the distance protection according to (addresses 1111 to
1142) a three-phase measured voltage failure is recognised. This parameter can only
be set with DIGSI at Additional Settings.
2.19.1.5 Settings
Addresses which have an appended "A" can only be changed with DIGSI, under Ad-
ditional Settings.
The table indicates region-specific presettings. Column C (configuration) indicates the
corresponding secondary nominal current of the current transformer.
