GE Multilin L60 Line Phase Comparison Relay 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.87PC SCHEMESignal selection: mixed I_2 – K × I_1 (K = 0.00 to 0.25 insteps of 0.01), or 3I_0Angle reference: 0 to 360° leading in steps of 1Fault detector low:Instantaneous overcurrent: 0.02 to 15.00 pu in steps of 0.01I2 × Z – V2 : 0.005 to 15.000 pu in steps of 0.001dI2 / dt: 0.01 to 5.00 pu in steps of 0.01dI1 / dt: 0.01 to 5.00 pu in steps of 0.01Fault detector high:Instantaneous overcurrent: 0.10 to 15.00 pu in steps of 0.01I2 × Z – V2 : 0.005 to 15.000 pu in steps of 0.001dI2 / dt: 0.01 to 5.00 pu in steps of 0.01dI1 / dt: 0.01 to 5.00 pu in steps of 0.01Signal symmetryadjustment: –5.0 to 5.0 ms in steps of 0.1Channel delayadjustment: 0.000 to 30.00 ms in steps of 0.001Channel adjustments: channel delay and signal symmetry com-pensationOperate time (typical): ¾ cycle for single phase comparison½ cycle for dual phase comparisonTrip security: first coincidence or enhancedSecond coincidence timer: 10 to 200 ms in steps of 1Enhanced stability angle: 40 to 180° in steps of 1PHASE DISTANCECharacteristic: mho (memory polarized or offset) orquad (memory polarized or non-direc-tional)Number of zones: 3Directionality: forward, reverse, or non-directionalReach (secondary Ω): 0.02 to 500.00 Ω 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 Ω in steps of 0.01Characteristic angle: 60 to 90° in steps of 1Left Blinder (Quad only):Reach: 0.02 to 500 Ω 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 0.001Operation time: 1 to 1.5 cycles (typical)Reset time: 1 power cycle (typical)GROUND DISTANCECharacteristic: Mho (memory polarized or offset) orQuad (memory polarized or non-direc-tional)Reactance polarization: negative-sequence or zero-sequencecurrentNon-homogeneity angle: –40 to 40° in steps of 1Number of zones: 3Directionality: forward, reverse, or non-directionalReach (secondary Ω): 0.02 to 500.00 Ω 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 1Distance comparator 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 1Zero-sequence compensationZ0/Z1 magnitude: 0.00 to 10.00 in steps of 0.01Z0/Z1 angle: –90 to 90° in steps of 1Zero-sequence mutual compensationZ0M/Z1 magnitude: 0.00 to 7.00 in steps of 0.01Z0M/Z1 angle: –90 to 90° in steps of 1Right blinder (Quad only):Reach: 0.02 to 500 Ω in steps of 0.01Characteristic angle: 60 to 90° in steps of 1Left blinder (Quad only):Reach: 0.02 to 500 Ω in steps of 0.01Characteristic angle: 60 to 90° in steps of 1Time delay: 0.000 to 65.535 s in steps of 0.001NOTE
