GE Multilin F60 Feeder Protection System 5-1375 SETTINGS 5.4 SYSTEM SETUP5• PMU 1 CURR TRIGGER PICKUP: This setting specifies the pickup threshold for the overcurrent trigger, in per unit ofthe PMU source. A value of 1 pu is a nominal primary current. The comparator applies a 3% hysteresis.• PMU 1 CURR TRIGGER PKP TIME: This setting can be used to filter out spurious conditions and avoid unnecessarytriggering of the recorder.• PMU 1 CURR TRIGGER DPO TIME: This setting can be used to extend the trigger after the situation returned to nor-mal. This setting is of particular importance when using the recorder in the forced mode (recording as long as the trig-gering condition is asserted).Figure 5–50: CURRENT TRIGGER SCHEME LOGICi) POWER TRIGGERINGPATH: SETTINGS SYSTEM SETUP PHASOR MEASUREMENT... PMU 1 TRIGGERING PMU 1 POWER TRIGGERThis element responds to abnormal power. Separate thresholds are provided for active, reactive, and apparent powers. Interms of signaling its operation the element does not differentiate between the three types of power. The trigger responds tothe single-phase and three-phase power signals of the phasor measurement unit (PMU) source.• PMU 1 POWER TRIGGER ACTIVE: This setting specifies the pickup threshold for the active power of the source. Forsingle-phase power, 1 pu is a product of 1 pu voltage and 1 pu current, or the product of nominal secondary voltage,the VT ratio and the nominal primary current. For the three-phase power, 1 pu is three times that for a single-phasepower. The comparator applies a 3% hysteresis.
