5 SETTINGS
•
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.
•
PMU 1 POWER TRIGGER APPARENT: This setting specifies the pickup threshold for the apparent 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.
•
PMU 1 POWER TRIGGER PKP TIME: This setting could be used to filter out spurious conditions and avoid unneces-
sary triggering of the recorder.
•
PMU 1 POWER TRIGGER DPO TIME: This setting could be used to extend the trigger after the situation returned to
normal. This setting is of particular importance when using the recorder in the forced mode (recording as long as the
triggering condition is asserted).
