GE Multilin D30 Line Distance Protection System 2-92 PRODUCT DESCRIPTION 2.2 SPECIFICATIONS22.2SPECIFICATIONSSPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE2.2.1 PROTECTION ELEMENTSThe operating times below include the activation time of a trip rated form-A output contact unless otherwise indi-cated. FlexLogic™ operands of a given element are 4 ms faster. This should be taken into account when usingFlexLogic™ to interconnect with other protection or control elements of the relay, building FlexLogic™ equations, orinterfacing with other IEDs or power system devices via communications or different output contacts.PHASE DISTANCECharacteristic: mho (memory polarized or offset) orquad (memory polarized or non-direc-tional), selectable individually per zoneNumber of zones: 3Directionality: forward, reverse, or non-directional perzoneReach (secondary ): 0.02 to 500.00 in steps of 0.01Reach accuracy: ±5% including the effect of CVT tran-sients up to an SIR of 30Distance:Characteristic angle: 30 to 90° in steps of 1Comparator limit angle: 30 to 90° in steps of 1Directional supervision:Characteristic angle: 30 to 90° in steps of 1Limit angle: 30 to 90° in steps of 1Right blinder (Quad only):Reach: 0.02 to 500 in steps of 0.01Characteristic angle: 60 to 90° in steps of 1Left Blinder (Quad only):Reach: 0.02 to 500 in steps of 0.01Characteristic angle: 60 to 90° in steps of 1Time delay: 0.000 to 65.535 s in steps of 0.001Timing accuracy: ±3% or 4 ms, whichever is greaterCurrent supervision:Level: line-to-line currentPickup: 0.050 to 30.000 pu in steps of 0.001Dropout: 97 to 98%Memory duration: 5 to 25 cycles in steps of 1VT location: all delta-wye and wye-delta transformersCT location: all delta-wye and wye-delta transformersVoltage supervision pickup (series compensation applications):0 to 5.000 pu in steps of 0.001PHASE DISTANCE OPERATING TIME CURVESThe operating times are response times of a microprocessor partof the relay. See output contacts specifications for estimation ofthe total response time for a particular application. The operatingtimes are average times including variables such as fault inceptionangle or type of a voltage source (magnetic VTs and CVTs).NOTE837717A1.CDRPhase Element (21P)0510152025300% 10% 20% 30% 40% 50% 60% 70% 80%Fault Location [%]Operating Time [ms]SIR = 0.1SIR = 1SIR = 10SIR = 20SIR = 30
