To view flicker metering values, enter the following command:
=> MET FL <Enter>
Reset the flicker metering values using the MET FL R command from Access
Level 2.
MET H (Harmonic Metering)
The MET H command displays the following quantities:
➤ Harmonic magnitudes for each measured input quantity
reported in secondary units
➤ KFACTOR for each measured phase current channel
➤ Total Harmonic Distortion per phase
➤ Distortion Power ratio
To view harmonic metering values, enter the following command:
=>MET H <Enter>
The output from an SEL-734 Meter with Form 9 voltage inputs is shown:
MET H I (Harmonic Magnitudes and Angles for Current)
The MET H I command displays harmonic current magnitudes (in secondary
units) and angles in degrees.
MET H M (Harmonic Metering Magnitude)
The MET H M command displays harmonic values as absolute magnitudes.
MET H P (Harmonic Magnitudes for Power)
The MET H P command displays harmonic power magnitudes in secondary
units.
MET H V (Harmonic Magnitudes and Angles for Voltage)
The MET H V command displays harmonic voltage magnitudes in secondary
units and angles in degrees.
MET L (Transformer/Line Loss Metering)
The MET L command displays the following quantities:
➤ Supply and load line losses
➤ Transformer losses
To view energy metering values, enter the following command:
=>MET L <Enter>
MET (Instantaneous Metering)
The MET command displays instantaneous fundamental magnitudes (and
angles if applicable) and rms magnitudes of the quantities in Table 10.12.
