This screen (Fig. 172) displays, with graphic and numeric indications, the phase delays,

expressed in degrees [°], between current I1 and I2, I2 and I3, I3 and I1 and the vector

representing the neutral current (blue – not for PQA400).

or Aron system

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 phase 1 vector diagram.

This screen (Fig. 173) displays, with graphic and numeric indications, the phase delays,

expressed in degrees [°], between voltage V1 and current I1, so that the inductive or

capacitive nature of the electrical installation may be found out. In detail:

 Positive angle: Inductive load.

 Negative angle: Capacitive load.
