Power Quality Monitoring
Chapter 5
Setup
Basic Metering setup is required. Three configuration parameters required for
calculating the IEEE 519 Pass/Fail requirements are found in the
Configuration.PowerQuality tab.
•
IEEE519_Compliance_Parameter - Selects 0 = current (default) or 1 =
voltage as the compliance parameter.
•
IEEE519_MAX_Isc_Amps - Short circuit current available at the PCC,
in Amps. Default = 0
•
IEEE519_MAX_IL_Amps - Average current related to the maximum
demand for the preceding 12 months. Default = 0
IEEE 519 Pass/Fail Results
The PowerMonitor 5000 reports the IEEE 519 pass/fail status for short term and
long term conditions in the
table in the tags listed below. If the
values of IEEE519_MAX_Isc_Amps = 0 or IEEE519_MAX_IL_Amps = 0,
then the first row in
IEEE 519 Current Distortion Limits is used to
measure compliance. If the value of IEEE519_MAX_IL_Amps = 0, then current
THD rather than TDD is used to measure compliance.
IEEE519_Overall_Status
This bitfield reports overall status.
0 = PASS
1 = FAIL

IMPORTANT
Zero values for Max Isc and IL disable the calculation.
