READ PWQT
PWQT Description
PF
Per phase power factor; when WIRI is selected as “3 3T”, “3 2T”, “3 1T” or “1N1T”, this
data is absent
PFT Total power factor
THDV Total harmonic distortion of voltage
THDI Total harmonic distortion of current
UNBL
Unbalances values for line to neutral voltage (VLN), line to line voltage (VLL) and
current (I); when WIRI is selected as “1N1T”, this data is absent
Individual harmonics are present only via Modbus RTU and Modbus TCP/IP communication.
