2-16 F60 Feeder Protection System GE Multilin2.2 SPECIFICATIONS 2 PRODUCT DESCRIPTION22.2SPECIFICATIONSSPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE2.2.1 PROTECTION ELEMENTSThe operating times include the activation time of a trip rated form-A output contact unless otherwise indicated.FlexLogic operands of a given element are 4 ms faster. Take this into account when using FlexLogic to interconnectwith other protection or control elements of the relay, building FlexLogic equations, or interfacing with other IEDs orpower system devices via communications or different output contacts. If not specified, operate times are givenhere for a 60 Hz system at nominal system frequency. Operate times for a 50 Hz system are 1.2 times longer.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:for 0.1 to 2.0 CT: ±0.5% of reading or ±0.4% of rated(whichever is greater)for > 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)Curve timing accuracyat 1.03 to 20 x pickup: ±3.5% of operate time or ±½ cycle(whichever is greater) from pickup tooperatePHASE/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)Timer accuracy: ±3% of operate time or ±1/4 cycle(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-earCurve timing accuracyat 1.03 to 20 x pickup: ±3.5% of operate time or ±½ cycle(whichever is greater) from pickup tooperateNEGATIVE 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 HzTimer accuracy: ±3% of operate time or ±1/4 cycle(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
