5.7.3.4. Vectors
This screen (Fig. 205) displays, with graphic and numeric indications, the phase delays
expressed in degrees [°] between:
 Voltage V1 and V2, V2 and V3, V3 and V1.
 Voltage V1 and current I1.
 Voltage V2 and current I2.
 Voltage V3 and current I3.
The latter allow finding out the inductive or capacitive nature of the electrical installation. In
detail:
 positive angle: inductive load
 negative angle: capacitive load
The N-PE voltage (blue) and Neutral current vectors are also represented.

The following keys are active on this page:
 The
F1 key (or the PAG item on the display) advances to the following page
of saved values relative to the voltage vector diagram.
 The
ESC key (or the smart icon on the display) to exit the function and go
back to the “Recording analysis” page (Fig. 181).
This screen (Fig. 206) displays, with graphic and numeric indications, the phase delays
expressed in degrees [°] between:
 Voltage V12 and V23, V23 and V31, V31 and V12.
 Voltage V12 and current I1.
 Voltage V23 and current I2.
 Voltage V31 and current I3.
To correctly evaluate this vector diagram, it must be remembered that, under purely
resistive loads, the angle between the Delta voltage and the phase current is +30°.
