In this page, the following symbols are used:
V1N

 Phase L1 - Neutral 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
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.
