5.2.7. Vectorial diagrams screens
Starting from a any page of numerical values it’s possible to select the vectorial diagrams
screens of voltage and currents by pressing F4 key (or touch “VECTORS” at display). The
aim of this feature is to show, with numerical and graphical indications, the phase angles,
expressed in degree [°] between the three voltages V1, V2 and V3 and the currents I1, I2
and I3 in order to understand in each moment the inductive or capacitive loads nature of
electrical installations. By pressing cyclically F1 key the below screens are shown by
meter:
Vectorial diagram total of phase angles among V1, V2, V3 and between V1-I1, V2-I2,
V3-I3 more than indication of percentage values of “NEG%” e “ZERO%” parameters
