GE Multilin D30 Line Distance Protection System 5-2015 SETTINGS 5.6 GROUPED ELEMENTS5b) PHASE UNDERVOLTAGE (ANSI 27P, IEC PTUV)PATH: SETTINGS GROUPED ELEMENTS SETTING GROUP 1(6) VOLTAGE ELEMENTS PHASE UNDERVOLTAGE1(3)This element may be used to give a desired time-delay operating characteristic versus the applied fundamental voltage(phase-to-ground or phase-to-phase for wye VT connection, or phase-to-phase for delta VT connection) or as a definitetime element. The element resets instantaneously if the applied voltage exceeds the dropout voltage. The delay settingselects the minimum operating time of the phase undervoltage. The minimum voltage setting selects the operating voltagebelow which the element is blocked (a setting of “0” will allow a dead source to be considered a fault condition).Figure 5–95: PHASE UNDERVOLTAGE1 SCHEME LOGIC PHASE UNDERVOLTAGE1PHASE UV1FUNCTION: DisabledRange: Disabled, EnabledMESSAGE PHASE UV1 SIGNALSOURCE: SRC 1Range: SRC 1, SRC 2MESSAGE PHASE UV1 MODE:Phase to GroundRange: Phase to Ground, Phase to PhaseMESSAGE PHASE UV1PICKUP: 1.000 puRange: 0.000 to 3.000 pu in steps of 0.001MESSAGE PHASE UV1CURVE: Definite TimeRange: Definite Time, Inverse TimeMESSAGE PHASE UV1DELAY: 1.00 sRange: 0.00 to 600.00 s in steps of 0.01MESSAGE PHASE UV1 MINIMUMVOLTAGE: 0.100 puRange: 0.000 to 3.000 pu in steps of 0.001MESSAGE PHASE UV1 BLOCK:OffRange: FlexLogic operandMESSAGE PHASE UV1TARGET: Self-resetRange: Self-reset, Latched, DisabledMESSAGE PHASE UV1EVENTS: DisabledRange: Disabled, EnabledPHASE UV1FUNCTION:PHASE UV1BLOCK:PHASE UV1 SOURCE:PHASE UV1 MODE:PHASE UV1PICKUP:PHASE UV1CURVE:PHASE UV1DELAY:PHASE UV1MINIMUM VOLTAGE:Off = 0Source VT = DeltaPhase to Ground Phase to PhaseRUNRUNVCG or VCA PICKUPVBG or VBC PICKUPVAG or VAB MinimumVBG or VBC MinimumVCG or VCA MinimumSource VT = WyeVAG VABVBG VBCVCG VCAEnabled = 1VABVBCVCAPHASE UV1 A PKPPHASE UV1 B PKPPHASE UV1 C PKPPHASE UV1 PKPPHASE UV1 A DPOPHASE UV1 B DPOPHASE UV1 C DPOPHASE UV1 A OPPHASE UV1 B OPPHASE UV1 C OPPHASE UV1 OPANDSETTINGSETTINGSETTINGSETTINGSETTINGSETTINGFLEXLOGIC OPERANDSFLEXLOGIC OPERANDFLEXLOGIC OPERAND827039AC.CDRANDANDANDOROR<<<<<}tVttVVVAG or VAB PICKUP<RUNPHASE UV1 DPOFLEXLOGIC OPERANDAND
