Fig. 1.5 E350 – Phase summation samples
In addition to the usual quantities, the measured quantities active, reactive
and apparent energy have further possibilities such as:
Subtraction of reactive energy
|+R| – |–R|
Addition of reactive energy
|+R| + |–R|
Quadrants
+Ai, +Ac, –Ai, –Ac
etc.
More samples and applications are shown in the functional description.
The reactive energy (±Rc, ±Ri) is allocated to the 4 quadrants as follows:
+R
+ kWh
- kWh
-R
+Ri
+Rc
-Rc

The reactive energies of the individual phases can be allocated to the 4
quadrants in the same way.
