CHAPTER 5: SETTINGS GROUPED ELEMENTSF60 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 5-2655This element is used to give a 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 definite timeelement. The element resets instantaneously if the applied voltage exceeds the dropout voltage. The delay setting selectsthe minimum operating time of the phase undervoltage. The minimum voltage setting selects the operating voltage belowwhich the element is blocked (a setting of “0” allows a dead source to be considered a fault condition).Figure 5-141: Phase undervoltage1 logic5.7.10.3 Phase overvoltage (ANSI 59P, IEC PTOV)SETTINGS GROUPED ELEMENTS SETTING GROUP 1(6) VOLTAGE ELEMENTS PHASE OVERVOLTAGE1(3) PHASE UV1TARGET: Self-resetRange: Self-reset, Latched, Disabled PHASE UV1EVENTS: DisabledRange: Disabled, Enabled PHASE OVERVOLTAGE1 PHASE OV1FUNCTION: DisabledRange: Disabled, Enabled PHASE OV1 SIGNALSOURCE: SRC 1Range: SRC 1, SRC 2, SRC 3, SRC 4 PHASE OV1PICKUP: 1.000 puRange: 0.004 to 3.000 pu in steps of 0.001 PHASE OV1 PICKUPDELAY: 1.00 sRange: 0.00 to 600.00 s in steps of 0.01 PHASE OV1 RESETDELAY: 1.00 sRange: 0.00 to 600.00 s in steps of 0.01 PHASE OV1 BLOCK:OffRange: FlexLogic Operand PHASE OV1TARGET: Self-resetRange: Self-reset, Latched, Disabled PHASE OV1EVENTS: DisabledRange: Disabled, Enabled
