Tangent φ total on all three phases

total

tan

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
