Long-term Timed Recording, Demand, Energy: Performing a statistically valid power
Monitoring
modes
quality energy survey requires the capture of a set of basic data over an extended period
(continued)
of time. The 4400 is designed to facilitate long-term monitoring by collecting min/max/
avg data at each pre-determined interval in order to perform post-process harmonic and
other events analysis. It is also designed to be left unattended in the field, recording
statistically representative data for long-term analysis. Using the Dranetz lockable
portable case option or other available enclosures, power quality studies can be carried
out in harsh weather environments.
Continuous Data Logging, Demand, Energy: This logs the rms and power values once
per second for totally gapless logging. Cyclic triggers are disabled. No waveforms are
recorded in this monitoring mode.
EN50160 Power Quality: EN50160 monitors and reports Quality of Supply (QOS)
compliance as specified by the EN standard. The seven parameters required by
EN50160 to determine QOS compliance are: Power Frequency, Supply Voltage
Variations, Flicker, Supply Voltage Unbalance, Harmonic Voltage, Interharmonic
Voltage, and Mains Signalling. A full discussion on EN50160 is found on Chapter 8
Reports.
