Alarm Conditions - AEMC PowerPad III 8336 User Manual

6.4.4 ALARM CONDITIONS

The Alarm Conditions tab allows you to set up 40 alarm configurations.
■ Prev Page & Next Page: Move between the 3 pages of alarms with 16 alarms per page.
■ Data to Capture: The alarm will be triggered based on the value of the selected parameter. Choices include:
None: no alarm
A CF: current crest factor
A DC: DC current
A Hf: current harmonic factor
A rms: current root mean squared
A pk+: maximum peak value of the
current
A pk-: minimum peak value of the
current
A THDf: harmonic distortion of the
current with the RMS value of the
fundamental as reference
A THDr: harmonic distortion of the
current with the total RMS value
without DC as reference
Aunb (u2): unbalance in current
100
Figure 6-10
Hz: frequency
P DC (W): Power (DC)
PF: power factor
Plt: long-term severity
Pst: short-term severity
P (W): power
Q (var): voltage/ampere
reactive
S (VA): volt/ampere
Tan Φ: Tangent of the phase
shift of the voltage with
respect to the current
VΦ-Φ CF: phase-to-phase
voltage crest factor
VΦ-Φ rms: phase-to-phase voltage
root mean squared
VΦ-Φ THDf: harmonic distortion of
the phase-to-phase voltage with the
fundamental RMS value as reference
VΦ-Φ THDr: harmonic distortion
of the phase-to-phase voltage with
the total RMS value without DC as
reference
VΦ-N CF: phase-to-neutral voltage
crest factor
VΦ-N DC: DC phase-to-neutral
voltage
VΦ-N Hf: phase-to-neutral voltage
harmonic factor
VΦ-N pk+: maximum phase-to-
neutral voltage
VΦ-N pk-: minimum phase-to-neutral
voltage
VΦ-N rms: phase-to-neutral voltage
root mean squared
VΦ-N THDf: harmonic distortion of
the phase-to-neutral voltage with the
fundamental RMS value as reference
