In this page, the following symbols are used:

V3PE  Phase L3 - PE Voltage

I3  Phase L3 current

Patt3  Phase L3 active power

Preatt3  Phase L3 reactive power

Papp3  Phase L3 apparent power

Pf3  Phase L3 power factor

CosPhi3  Cosine of the phase delay between the Phase L3

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.

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
