
in the upper half plane of the graph if the harmonics are introduced into the relevant
electrical system from the mains;

in the lower half plane of the graph if the harmonics are injected into the relevant
electrical system from the mains.
The following keys are active on this page:

The up ( ZOOM+ ) or down ( ZOOM- ) arrow keys zoom in or out the histogram.

The right and left arrow keys move the cursor to the right or to the left along the
harmonics.

The F1 key (or the PAG item on the display) advances to the following page of saved
values, relative to phase 1 harmonics.

The F2 key (or the ARM V or ARM I item on the dislay) switches between total voltage
and current harmonics.

The F4 key (or the ARM PAG item on the display) displays the following harmonics
group. 0..9, 10..19, 20..29, 30..39, 40..49.

The ESC key (or the smart icon on the display) to exit the function and go back to the
“Recording analysis” page (Fig. 143).
5.7.3.4. Vectors
As an example, below are shown the screens relative to a three phase 4-wire system . Similar
consideration can be applied to any other selected system. This screen (Fig. 147) 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.
