SYSTEM SETUP
This element responds to elevated current. The trigger responds to the phase current signal of the Phasor Measurement
Unit (PMU) source. All current channel (A, B, and C) are processed independently and can trigger the recorder.

TRIGGER
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 among the three types of power. The trigger responds
to the single-phase and three-phase power signals of the Phasor Measurement Unit (PMU) source.

— Specifies the pickup threshold for the overcurrent trigger, in per unit of the PMU source. A
— Use to filter out spurious conditions and avoid unnecessary triggering of the recorder.
— Use to extend the trigger after the situation returns to normal. This setting is of
