GE Multilin F60 Feeder 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/NEUTRAL/GROUND TOCCurrent: Phasor or RMSPickup level: 0.000 to 30.000 pu in steps of 0.001Dropout level: 97% to 98% of pickupLevel accuracy:0.1 to 2.0 × CT: ±0.5% of reading or ±0.4% of rated(whichever is greater)> 2.0 × CT: ±1.5% of reading > 2.0 × CT ratingCurve shapes: IEEE Moderately/Very/ExtremelyInverse; IEC (and BS) A/B/C and ShortInverse; GE IAC Inverse, Short/Very/Extremely Inverse; I 2 t; FlexCurves™(programmable); Definite Time (0.01 sbase curve)Curve multiplier: Time Dial = 0.00 to 600.00 in steps of0.01Reset type: Instantaneous/Timed (per IEEE)Timing accuracy: Operate at > 1.03 × actual pickup±3.5% of operate time or ±½ cycle(whichever is greater)Voltage restraint: Modifies pickup current for voltage in therange of 0.1fixed linear relationshipPHASE/NEUTRAL/GROUND IOCPickup level: 0.000 to 30.000 pu in steps of 0.001Dropout level: 97 to 98% of pickupLevel accuracy:0.1 to 2.0 × CT rating: ±0.5% of reading or ±0.4% of rated(whichever is greater)> 2.0 × CT rating ±1.5% of readingOverreach: <2%Pickup delay: 0.00 to 600.00 s in steps of 0.01Reset delay: 0.00 to 600.00 s in steps of 0.01Operate time: <16 ms at 3 × pickup at 60 Hz(Phase/Ground IOC)<20 ms at 3 × pickup at 60 Hz(Neutral IOC)Timing accuracy: Operate at 1.5 × pickup±3% or ±4 ms (whichever is greater)NEGATIVE SEQUENCE TOCPickup level: 0.000 to 30.000 pu in steps of 0.001Dropout level: 97% to 98% of pickupLevel accuracy: ±0.5% of reading or ±0.4% of rated(whichever is greater)from 0.1 to 2.0 x CT rating±1.5% of reading > 2.0 x CT ratingCurve shapes: IEEE Moderately/Very/ExtremelyInverse; IEC (and BS) A/B/C and ShortInverse; GE IAC Inverse, Short/Very/Extremely Inverse; I 2 t; FlexCurves™(programmable); Definite Time (0.01 sbase curve)Curve multiplier (Time dial): 0.00 to 600.00 in steps of 0.01Reset type: Instantaneous/Timed (per IEEE) and Lin-earTiming accuracy: Operate at > 1.03 × actual pickup±3.5% of operate time or ±½ cycle(whichever is greater)NEGATIVE SEQUENCE IOCPickup level: 0.000 to 30.000 pu in steps of 0.001Dropout level: 97 to 98% of pickupLevel accuracy: 0.1 to 2.0 × CT rating: ±0.5% of readingor ±0.4% of rated (whichever is greater);> 2.0 × CT rating: ±1.5% of readingOverreach: < 2%Pickup delay: 0.00 to 600.00 s in steps of 0.01Reset delay: 0.00 to 600.00 s in steps of 0.01Operate time: < 20 ms at 3 × pickup at 60 HzTiming accuracy: Operate at 1.5 × pickup±3% or ±4 ms (whichever is greater)PHASE DIRECTIONAL OVERCURRENTRelay connection: 90° (quadrature)Quadrature voltage: ABC phase seq.: phase A (V BC ), phaseB (V CA ), phase C (VAB ); ACB phaseseq.: phase A (V CB ), phase B (VAC ),phase C (V BA )Polarizing voltage threshold: 0.000 to 3.000 pu in steps of 0.001Current sensitivity threshold: 0.05 puCharacteristic angle: 0 to 359° in steps of 1Angle accuracy: ±2°Operation time (FlexLogic™ operands):Tripping (reverse load, forward fault):<12 ms, typicallyBlocking (forward load, reverse fault):<8 ms, typicallyNOTE
