PMU 1 VOLT TRIGGER HIGH-VOLT
: This setting specifies the high threshold for the abnormal voltage trigger, in per-
unit of the PMU source. 1 pu is a nominal voltage value defined as the nominal secondary voltage times VT ratio. The
comparator applies a 3% hysteresis.
•
PMU 1 VOLT TRIGGER PKP TIME
: This setting could be used to filter out spurious conditions and avoid unnecessary
triggering of the recorder.
•
PMU 1 VOLT 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).

PHASOR MEASUREMENT...
PMU 1 TRIGGERING
PMU 1 CURRENT TRIGGER
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 could trigger the recorder.
•
PMU 1 CURR TRIGGER PICKUP
: This setting specifies the pickup threshold for the overcurrent trigger, in per unit of
the PMU source. A value of 1 pu is a nominal primary current. The comparator applies a 3% hysteresis.
•
PMU 1 CURR TRIGGER PKP TIME
: This setting could be used to filter out spurious conditions and avoid unneces-
sary triggering of the recorder.
