Power quality 9810 series - User manual
195 7EN05-0390-08
Power quality
Your meter measures voltage and current harmonics, and calculates several harmonic distortion
values, including K-factor and crest factor.
Configure your meter with the power system’s nominal values for voltage, current, and frequency
for the meter to perform power quality calculations.
Power quality configuration
Use ION Setup to configure sag/swell, transient and advanced power quality logging.
NOTE: For waveform recording to trigger automatically, enter your system’s nominal (normal)
voltage and current values and the amount of deviation from the nominal that is considered a
sag or a swell using the Metering > Basic or Alarming screen
NOTE: Changing your meter’s data logging (including burst data logging) and waveform
recording configuration clears your meter’s existing data logs, waveform records and
COMTRADE waveform files.
Before setting up the Power Quality (PQ) parameters, make sure the meter is configured
correctly:
•
Metering parameters such as volts mode and PT/CT ratios
•
Time sync settings, for integrating the meter in an energy management system such as
WinPM.Net
•
Nominal system parameters (nominal volts, nominal current and nominal frequency), for
detecting power quality events
•
Amount of deviation from the nominal that is considered a sag or swell
Make sure you understand:
•
The structure of the meter’s logging framework
•
The meter’s existing logging configuration
•
Your data logging requirements
Changing the meter’s data recorder and waveform recorder configuration clears existing data and
waveforms in those recorders.
NOTICE
DATALOSS
Failure to follow these instructions can result in data loss.
Ensure that all important data and waveforms have been recorded before configuring the data
and waveform recorders.
