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  Phase L1 Apparent Power
Pf1  Phase L1 Power Factor
CosPhi1  Cosine of the phase delay between the Phase L1
voltage and current fundamentals
CosPhi represents the theoretical limit value which
