5.5.2.4. Vectors

This screen (Fig. 167) 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 (pale blue - not for PQA400) 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. 143).
