12. Configure the settings as required:
IEEE 519 Configuration
Parameter Description
Nominal Voltage Displays the nominal voltage value used for IEEE 519.
NOTE: If you change the Nominal Voltage, you must return to
this setup screen and manually update the IEEE 519
configuration.
<Bus voltage
options> Select the bus voltage at the point of common coupling.
Select
Disabled if you do not want to log IEEE 519 related data.
13. After specifying the bus voltage, click Next to configure the IEEE 519 current
parameters.
IEEE 519 Configuration
Parameter Description
Maximum short
circuit current Enter the maximum short-circuit current at the point of common
coupling.
Maximum demand
load current
Enter the maximum demand load current at the point of common
coupling.
Ratio This displays the maximum short-circuit to maximum demand load
ratio. This is used to determine the voltage and current distortion
limits.
14. Click Next to view the screen that displays the voltage and current distortion
limits for the harmonic content.
Harmonics 2 to 50 and THD/TDD are displayed, with the corresponding set
limits for Voltage Distortion % and Current Distortion %.
15. Click Finish to save your changes.
The Advanced PQ Logging screen shows the new configuration.
16. Select RVC enable and click Edit to configure your meter’s RVC (Rapid
Voltage Change) feature.
NOTE: You must enable the Sag/Swell module before the meter can start
monitoring and detecting RVC.
17. Configure the settings as required:
Rapid Voltage Change Setup
Parameter Description
Enabled • Disabled means ION Setup has detected that the Sag/Swell module
is disabled. Go to
Alarming
>
Sag/Swell and enable Sag/Swell first,
in order for the meter to detect RVC.
• Yes means RVC monitoring is on. Make sure the Sag/Swell module
is enabled, otherwise RVC will not be detected.
• No means RVC monitoring is off.
Threshold Specifies, as a percentage, the RMS voltage limit that must be exceeded
for an RVC event to occur.
Hysteresis Specifies, as a percentage, the difference in magnitude between the start
and end thresholds for an RVC event.
18. Click Send to save your changes.
