In this page, the following symbols are used:
V12

 Phase L1 - Phase L2 Voltage

V23

 Phase L2 - Phase L3 Voltage

V31

 Phase L3 - Phase L1 Voltage

Inv%

 % value of the Negative sequence unbalance

Omo%

 % value of the Zero sequence unbalance

SEQ Phase

sequence:

”123” => Correct
”132” => Not correct
”023” => No Voltage on B1
”103” => No Voltage on B2
”120” => No Voltage on B3
”100” => No Voltage on B2 and B3
”020” => No Voltage on B1 and B3
”003” => No Voltage on B1 and B2
Hz

 Frequency

I1

 Current on Phase L1

I2

 Current on Phase L2

I3

 Current on Phase L3

The following keys are active on this page:
 The

F1 key (or the PAG item on the display) advances to the following page.

 The ESC key (or the smart icon on the display) to exit the function and go back to the

“Recording analysis” page (Fig. 124).

In this page, the following symbols are used:
Patt

 System total Active Power

Preatt

 Total Reactive Power

Papp

 Total Apparent Power

Pf

 Total Power Factor

CosPhi

 System total CosPhi


CosPhi represents the theoretical limit value which
can be reached by the Power factor if all harmonics
are eliminated from the electrical system. For
dimensioning a power factor correction system,
reference is usually made to the CosPhi parameter
value.
