• PMU 1 CURR TRIGGER PKP TIME: This setting could be used to filter out spurious conditions and avoid unneces-
sary triggering of the recorder.
• PMU 1 CURR TRIGGER DPO TIME: This setting could 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).

This element responds to abnormal power. Separate thresholds are provided for active, reactive, and apparent powers. In
terms of signaling its operation the element does not differentiate between the three types of power. The trigger responds to
the 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. For
single-phase power, 1 pu is a product of 1 pu voltage and 1 pu current, or the product of nominal secondary voltage,
