Explanation of Power Harmonics Angle Parameters
The parameters PWH1 V1/V2/V3 Angle and PWH1 I1/I2/I3 Angle are sourced from the Power Harmonics module under the Fundamental Power group. These parameters represent the phase angles, measured in degrees, of voltage and current for each phase at the fundamental frequency.
- PWH1 V1 Angle → Phase angle of Voltage Phase A
- PWH1 V2 Angle → Phase angle of Voltage Phase B
- PWH1 V3 Angle → Phase angle of Voltage Phase C
- PWH1 I1 Angle → Phase angle of Current Phase A
- PWH1 I2 Angle → Phase angle of Current Phase B
- PWH1 I3 Angle → Phase angle of Current Phase C
These values are commonly used for power quality analysis and phase relationship verification at the fundamental frequency.
