GE Multilin D30 Line Distance Protection System 5-1535 SETTINGS 5.6 GROUPED ELEMENTS5The ground mho distance function uses a dynamic 100% memory-polarized mho characteristic with additional reactance,directional, current, and phase selection supervising characteristics. The ground quadrilateral distance function is com-posed of a reactance characteristic, right and left blinders, and 100% memory-polarized directional, overcurrent, and phaseselection supervising characteristics.When set to non-directional, the mho function becomes an offset mho with the reverse reach controlled independently fromthe forward reach, and all the directional characteristics removed. When set to non-directional, the quadrilateral functionapplies a reactance line in the reverse direction instead of the directional comparators.MESSAGE GND DIST Z1REACH: 2.00 ΩRange: 0.02 to 500.00 ohms in steps of 0.01MESSAGE GND DIST Z1RCA: 85°Range: 30 to 90° in steps of 1MESSAGE GND DIST Z1 REVREACH: 2.00 ΩRange: 0.02 to 500.00 ohms in steps of 0.01MESSAGE GND DIST Z1 REVREACH RCA: 85°Range: 30 to 90° in steps of 1MESSAGE GND DIST Z1 POLCURRENT: Zero-seqRange: Zero-seq, Neg-seqMESSAGE GND DIST Z1 NON-HOMOGEN ANG: 0.0°Range: –40.0 to 40.0° in steps of 0.1MESSAGE GND DIST Z1COMP LIMIT: 90°Range: 30 to 90° in steps of 1MESSAGE GND DIST Z1DIR RCA: 85°Range: 30 to 90° in steps of 1MESSAGE GND DIST Z1DIR COMP LIMIT: 90°Range: 30 to 90° in steps of 1MESSAGE GND DIST Z1 QUADRGT BLD: 10.00 ΩRange: 0.02 to 500.00 ohms in steps of 0.01MESSAGE GND DIST Z1 QUADRGT BLD RCA: 85°Range: 60 to 90° in steps of 1MESSAGE GND DIST Z1 QUADLFT BLD: 10.00 ΩRange: 0.02 to 500.00 ohms in steps of 0.01MESSAGE GND DIST Z1 QUADLFT BLD RCA: 85°Range: 60 to 90° in steps of 1MESSAGE GND DIST Z1SUPV: 0.200 puRange: 0.050 to 30.000 pu in steps of 0.001MESSAGE GND DIST Z1 VOLTLEVEL: 0.000 puRange: 0.000 to 5.000 pu in steps of 0.001MESSAGE GND DIST Z1DELAY: 0.000 sRange: 0.000 to 65.535 s in steps of 0.001MESSAGE GND DIST Z1 BLK:OffRange: FlexLogic operandMESSAGE GND DIST Z1TARGET: Self-ResetRange: Self-Rest, Latched, DisabledMESSAGE GND DIST Z1EVENTS: DisabledRange: Disabled, Enabled
