Simultaneous measurement of various power quality parameters
The following power quality parameters can be simultaneously mea-
sured and recorded.
• Transient overvoltage (impulse)
• Voltage swells, voltage dips, interruptions, frequency, voltage, voltage
waveform peaks, current, current waveform peaks, active power,
apparent power, reactive power, power factor, displacement power
factor, voltage unbalance factor, harmonic voltage, harmonic current,
harmonic power, fundamental voltage phase difference, fundamental
current phase difference, total harmonic voltage distortion factor
(THD-F), K factor, active power value, reactive power value, active
power demand, reactive power demand
See:
"Detecting Anomalies and Phenomena Due to Drops in Power Quality"
(p. A14)
Display time series plots of rms values and voltage fluctuations
Record and display fluctuations in various power quality parameters as a
time series plot.
Display and record calculated maximum, average and minimum values
during each measurement interval.
Rms voltage is calculated for one waveform shifted by half of a cycle,
and is recorded and displayed as a time series plot of voltage fluctua-
tions to detect voltage swell, voltage dip and interruption events.
Measure demand and energy consumption
Measure polarity-specific demand parameters such as consumption,
regeneration, lag, lead and energy consumption. Demand and energy
consumption can be verified on a time series plot.
Event detection function
Set thresholds at which to detect and record events while measuring.
Detected events can be analyzed using the event monitor, event list or
event waveform display.
Event detection is available for voltage swells, voltage dips (instanta-
neous dips), interruptions, inrush current, transient overvoltage, timed
and manually triggered events.
Measure inrush current
Measure motor startup current. Rms current is recorded for 30 seconds
and displayed graphically.
Internal memory with backup battery preserves recorded mea-
surement data
Measurement data is recorded into the 4 MB internal memory and
retained by a lithium-ion battery that should not require replacement for
about 10 years. So data is preserved even during power outages.
