Angle Offset Specifies a phase angle offset to be applied to the channel. The offset
is included in:
• Meter readings
• Trigger calculations
• Low speed recordings (phasors)
• Trend channels
• Output to calculated channels (watts, vars, Impedance, Summa-
tions, Sequence components, etc.) that use this channel as their
input.
High speed recordings of this channel will not have the phase angle
applied as they are basic representations of the individual sampled
points.
When the Angle Offset is used on a channel that has been designated
as the reference channel, it affects the angle measurement of all other
channels. (See: “Phase Angle Reference Channel” on page 8-10).
Trigger Settings
Rate of Change
Interval Specifies the period of time over which both positive and negative rate
of change is measured. 0.5 to 8.0 cycles.
Single Harmonic
Number Selects the harmonic of fundamental frequency that will be used by
the Single Harmonic trigger. 2 to the highest harmonic allowed, which
is the 25th harmonic.
Nominal Level Provides a nominal level for the sag and swell detectors. Available on
voltage channels only. See sag and swell detector details below.
Limit Specifies the trigger levels for the magnitude, single harmonic, THD,
sag and swell triggers. Specifies the magnitude portion of the rate for
rate of change triggers.
Delay Specifies how long the trigger condition must be present before a trig-
ger is declared.
Magnitude and Rate of Change triggers: 0 to 1,200 seconds in half-
cycle increments.
Single harmonic and THD triggers: 1 to 10,000 seconds in 1 second
increments.
Trigger Actions
Enable Enables or disables the associated trigger. A trigger can be disabled
without altering the rest of its settings.
Fault Initiates a fault (high speed) recording when triggered.
Swing Initiates a swing (low speed) recording when triggered.
If both Fault and Swing are enabled, the recorder will attempt to cre-
ate a combined record.
Log Logs a message in the Event Log when triggered.
Notify Contacts the RecordBase Central Station when triggered. Can be
used to initiate wide area swing recordings and/or automated record
transfer (“Notify” on page 7-13)
Cross Trigger Activates the cross-trigger contact (#6) to trigger another device.
Priority Specifies the priority to be assigned to records created by this trigger.
The priority is used to determine Central Station notification.
1 - 3 (3 is the highest priority). (“Notify” on page 7-13).
