Description of the menu | 39
FRAKO | Operating Manual | Power Quality Controller – PQC
6.2.2 System & PQ
Main menu > Display > System & PQ
6.2.2.1 Network variables
Main menu > Display > System & PQ > Network variables
cosφ Display of the momentary power factor cosφ
V∆ /V V∆ phase-phase voltage / V phase-neutral
voltage
P Display of the momentary active power
Q Display of the momentary reactive power
(if capacitive reactive power with a minus sign)
I Display of the momentary current
S Display of the momentary apparent power
∑ Sum of all the phases (L1 to L3); if a single-phase PQC, theoretical
calculation of the sum assuming a balanced load
6.2.2.2 THD
Main menu > Display > System & PQ > THD
Display of THDv and THDi and their magnitudes as per-
centages of the fundamental H1
Single phase PQC: display of Lx and Ix
3-phase PQC: display of all three THDv and THDi values
6.2.2.3 V/I Harmonics
Main menu > Display > System & PQ > V/I Harmonics
Display of percentage values of the voltage and current
harmonics together with the fundamental values for
voltage and current. With a 3-phase PQC, pressing the
key toggles the display through the phases L1 to L3.
