5.3.6 Display of Fresnel Diagram
This sub-menu displays the absolute values of the voltages and currents at the
fundamental frequency, the phase displacement of the voltages relative to the cur-
rents and the unbalances of the voltages and currents.
NOTE:
The display screen varies depending on which value is selected.
3U:
D
isplays a vector representation of the fundamentals of the phase-to-phase
voltages and of the currents. It indicates their associated quantities (modulus and
phase of the phase-to-phase voltage vectors) and the voltage unbalance. The
reference vector of the representation (at 3 o’clock) is U1.
3V:
D
isplays a vector representation of the fundamentals of the phase-to-neutral
voltages and of the currents. It indicates their associated quantities (modulus and
phase of the phase-to-neutral voltage vectors) and the voltage unbalance. The
reference vector of the representation (at 3 o’clock) is V1.
3A:
D
isplays a vector representation of the fundamentals of the phase-to-neutral
voltages and of the currents. It indicates their associated quantities (modulus and
phase of the current vectors) and the current unbalance. The reference vector of
the representation (at 3 o’clock) is A1.
L1/L2/L3:
D
isplays a vector representation of the fundamentals of the phase-
to-neutral voltages and the currents of one phase. It indicates their associated
quantities (modulus and phase of the current and phase-to-neutral voltage
vectors). The reference vector of the representation (at 3 o’clock) is the current
vector.
