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.

In this page, the following symbols are used:
V1PE

 Phase L1 - PE Voltage

I1

 Phase L1 Current

Patt1

 Phase L1 Active Power

Preatt1

 Phase L1 Reactive Power

Papp1

CosPhi1

 Cosine of the phase delay between the Phase L1

voltage and current fundamentals
