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,
the VT ratio and the nominal primary current. For the three-phase power, 1 pu is three times that for a single-phase
power. The comparator applies a 3% hysteresis.
• PMU 1 POWER TRIGGER REACTIVE: This setting specifies the pickup threshold for the reactive 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 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.
