FAQ
What is Four Quadrant Metrology?
P—active energy; Q—reactive energy; QL—inductive reactive energy; QC—capacitive reactive energy; S—apparent power Forward active power: P=UICOSΦ, where the range of Φ is within ±90°. Reverse active power: P=UICOSΦ, where Φ ranges from 90° to 270° Forward reactive power: P= UISINΦ, where the range of Φ is within 0~180°...
