ÖØ PMU 1 TRIGGERING ÖØ 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.• PMU 1 POWER TRIGGER REACTIVE: This setting specifies the pickup threshold for the reactive power of thesource. For single-phase power, 1 pu is a product of 1 pu voltage and 1 pu current, or the product of nominal second-ary voltage, the VT ratio and the nominal primary current. For the three-phase power, 1 pu is three times that for a sin-gle-phase power. The comparator applies a 3% hysteresis.
