LiveView Harmonic Apparent Power Flows
The harmonic apparent power flows table displays real-time apparent power flow information. Use this information to help determine the impact of harmonics on system equipment.
After opening the harmonic apparent power flows template, select the device, then click Display Table.
In the upper right, you can set the update interval for this table.
You can set meter registers to enable frequency domain analysis of waveforms and the format used in analysis. Harmonics and trend tables reflect these register settings. For details about these settings, read the Notes to the right of the table.
The harmonic apparent power flows table provides this data:
- meter type
- wiring type
- FFT magnitudes
- FFT enable
- FFT status
- FFT hold time
- remaining hold
- total voltage harmonic distortion for all three phases
- total current harmonic distortion for all three phases
- harmonic components for all three phases:
- power flow in from the utility
- power flow out to the utility
- apparent power
Magnitudes and angles are available for all odd harmonics from H1 through H31.
