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
Status.Alarms 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
Table 16 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
• Bit0 - ShortTerm_TDD_THD_PASS_FAIL
• Bit1 - LongTerm_TDD_THD_PASS_FAIL
• Bit2 - ShortTerm_Individual_Harmonic_PASS_FAIL
• Bit3 - LongTerm_Individual_Harmonic_PASS_FAIL
• Bit4 … 15 - Future Use
• ShortTerm_2nd_To_17th_Harmonic_Status
• LongTerm_2nd_To_17th_Harmonic_Status
These bitfields reports the short-term or long-term status of harmonics of order
2
… 17.
0 = PASS
1 = FAIL
• Bit0 - 2nd_Harmonic_PASS_FAIL
• Bit1 - 3rd_Harmonic_PASS_FAIL
• …
• Bit15 - 17th_Harmonic_PASS_FAIL
• ShortTerm_18th_To_33rd_Harmonic_Status
• LongTerm_18th_To_33rd_Harmonic_Status
IMPORTANT Zero values for Max Isc and IL disable the calculation.
