PQMII POWER QUALITY METER – INSTRUCTION MANUAL 6–23
• PHASE A/B/C/N CURRENT THD: These messages display the calculated total
harmonic distortion for each current input.
• VOLTAGE Van/Vbn/Vcn/Vab/Vbc THD: These messages display the calculated total
harmonic distortion for each voltage input. Phase-to-neutral voltages will appear
when the setpoint
S2 SYSTEM SETUP ÖØ CURRENT/VOLTAGE CONFIGURATION ÖØ VT WIRING is set
as “Wye”. Line-to-line voltages will appear when
VT WIRING is set as “Delta”.
• Ia/Ib/Ic/In MAX THD: The maximum total harmonic value for each current input and
the time and date which the maximum value occurred are displayed. The
S1 PQMII SETUP
