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 phase voltage, when WIRI is selected as ‘3 3T’, ‘3 2T’, ‘3
1T’, this data is absent
THDU
Total harmonic distortion of line voltage, when WIRI is selected as ‘3 3T’, ‘3 2T’, ‘3 1T’
or ‘1N1T’, this data is absent
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.
