CHAPTER 5: SETTINGS SYSTEM SETUPN60 NETWORK STABILITY AND SYNCHROPHASOR MEASUREMENT SYSTEM – INSTRUCTION MANUAL 5-1395This element responds to elevated current. The trigger responds to the phase current signal of the Phasor MeasurementUnit (PMU) source. All current channel (A, B, and C) are processed independently and can trigger the recorder.PMU 1 CURR TRIGGER PICKUP — Specifies the pickup threshold for the overcurrent trigger, in per unit of the PMU source. Avalue of 1 pu is a nominal primary current. The comparator applies a 3% hysteresis.PMU 1 CURR TRIGGER PKP TIME — Use to filter out spurious conditions and avoid unnecessary triggering of the recorder.PMU 1 CURR TRIGGER DPO TIME — Use to extend the trigger after the situation returns to normal. This setting is ofimportance when using the recorder in the forced mode (recording as long as the triggering condition is asserted).Figure 5-61: Current trigger logic5.5.6.16 Power triggeringSETTINGS SYSTEM SETUP PHASOR MEASUREMENT UNIT PHASOR MEASUREMENT UNIT 1(6) PMU 1(6)TRIGGERING PMU 1(6) 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 among the three types of power. The trigger respondsto the single-phase and three-phase power signals of the Phasor Measurement Unit (PMU) source.
