4.3.4 POWER READING POLARITIES
Figure 4.3.4 illustrates how the 3300 ACM interprets and
displays signed values for power, energy import/export
indication, and power factor leading/lagging indication.
NOTE
The polarity of energy import/export read-
ings can be reversed by reversing the polar-
ity of the CTs connected to the 3300 ACM.
