Appendix B -Settings and Signals
MENU TEXT
To enable (activate) or disable (turn off) or enable (only in the case that differential protection communication channel is lost) Zone 3 offset
reach for phase faults.
By default, Z3 Mho phase characteristic is offset (partly reverse directional), thus not memory/cross polarized. 'If Z3 Gnd Offset' is disabled, Z3
Mho characteristic becomes memory/cross polarized like all other zones.
Z3Ph Rev Reach
Setting entry as percentage of the line impedance that sets Zone 3 reverse reach in ohms.
Zone P Ph Status
To enable (activate) or disable (turn off) or enable (only in the case that differential protection communication channel is lost) ZP for phase
faults.
This setting is invisible if 'Phase Char.' is disabled.
Zone P Ph Dir.
To directionalize Zone P forward or reverse.
Zone P Ph Reach
Setting entry as percentage of the line impedance that sets Zone P forward or reverse reach in ohms.
Zone 4 Ph Status
To enable (activate) or disable (turn off) or enable (only in the case that differential protection communication channel is lost) Z4 for phase
faults.
This setting is invisible if 'Phase Char.' is disabled.
Zone 4 Ph Reach
Setting entry as percentage of the line impedance that sets reverse Zone 4 reach in ohms.
GROUND DISTANCE
Ground Chars.
Setting to disable (turn off) ground distance protection or to set Mho or Quad operating characteristic: ANSI 21G.
The chosen setting is applicable to all ground distance zones.
Quad Resistance
Setting to define the mode of resistive reach coverage. If 'Common' mode is selected, all ground distance zones will have the equal resistive
coverage. If 'Proportional' mode is selected, the zones will have resistive coverage according to the % reach set for the zone, multiplied by
the 'Fault Resistance' RG setting.
This setting is visible only when 'Simple' setting mode and quad characteristic are set.
Fault Resistance
Setting used to specify the fault arc resistance that can be detected for faults phase - ground. The set value determines the right hand side
of the quadrilaterals.
This setting is visible only when 'Simple' setting mode and quad characteristic are set.
Zone 1 Gnd Stat.
To enable (activate) or disable (turn off) or enable (only in the case that differential protection communication channel is lost) Zone 1 for
ground faults.
This setting is invisible if 'Ground Char.' is disabled.
