Active energy per phase and total Active power accumulated on each
logging interval
Note
The sign of the active power P gives the direction of the power flow
(positive: from generator to load), and the sign of the power factor
distinguishes between inductive load (positive) and capacitive load
(negative).
Sign of PF, tan φ, cos φ:
• Sign “+” : Q positive (“inductive”)
• Sign “–” : Q negative (“capacitive”) independent of the sign of active
power P
