DESCRIPTION
the value as long as ‘Simple’ mode setting remains active.
Advanced setting mode:
‘Advanced’ setting mode allows individual distance ohmic reaches and residual compensation factors to be entered for each zone. When
‘Advanced’ mode is selected, all ‘percentage’ settings that are associated to ‘Simple’ setting mode in the column GROUP x DISTANCE SETUP
will be hidden and the Distance zone settings need to be entered for each zone in the ‘GROUP x DIST. ELEMENTS’ column.
Phase Chars. 31 11 Mho
Mho
Quadrilateral
Disabled
Mho
Setting to disable (turn off) phase distance protection or to set Mho or Quad operating characteristic: ANSI 21P.
The chosen setting is applicable to all phase distance zones.
Quad Resistance 31 12 Proportional
Proportional
Setting to define the mode of resistive reach coverage. If ‘Common’ mode is selected, all phase 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’ RPH setting.
This setting is visible only when ‘Simple’ setting mode and quad characteristic are set.
Fault Resistance 31 13 10
From 0.1*v1/I1 to 500*V1/I1 in steps of 0.01*V1/I1
[Courier Number (impedance)]
Setting used to specify the fault arc resistance that can be detected for faults between phases. 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 Ph Status 31 20 Enabled
Enabled
Enabled Ch Fail
To enable (activate) or disable (turn off) or enable (only in the case that differential protection communication channel is lost) Z1 for phase
faults.
This setting is invisible if ‘Phase Char.’ is disabled.
Zone 1 Ph Reach 31 21 80
From 10 to 1000 in steps of 1
[Courier Number (percentage)]
Setting entry as percentage of the line impedance that sets Zone 1 reach in ohms.
Zone 2 Ph Status 31 30 Enabled
Enabled
Enabled Ch Fail
To enable (activate) or disable (turn off) or enable (only in the case that differential protection communication channel is lost) Z2 for phase
faults.
This setting is invisible if ‘Phase Char.’ is disabled.
Zone 2 Ph Reach 31 31 150
From 10 to 1000 in steps of 1
[Courier Number (percentage)]
Setting entry as percentage of the line impedance that sets Zone 2 reach in ohms.
Zone 3 Ph Status 31 40 Enabled
Enabled
Enabled Ch Fail
To enable (activate) or disable (turn off) or enable (only in the case that differential protection communication channel is lost) Z3 for phase
faults.
This setting is invisible if ‘Phase Char.’ is disabled.
Zone 3 Ph Reach 31 41 250
From 10 to 1000 in steps of 1
[Courier Number (percentage)]
Setting entry as percentage of the line impedance that sets Zone 3 forward reach in ohms.
Zone 3 Ph Offset 31 42 Enabled
Enabled
