7.6.4. L1 PHASOR DIAGRAM DISPLAY SCREEN
In the presence of the neutral, this screen displays 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.
|V1|: modulus of the vector of
the fundamental of the phase-to-
neutral voltage of phase 1.
|A1|: modulus of the vector of
the fundamental of the current of
Φ

neutral voltage of phase 1
relative to the fundamental of
the current of phase 1.
NOTE: L2 and L3 display vector representations of the fundamentals of the phase-to-neutral voltages and the currents of
phases 2 and 3, respectively. They indicate their associated quantities (modulus and phase of the current and phase-to-
neutral voltage vectors of phases 2 and 3, respectively). The reference vector of the representation (at 3 o'clock) is the
current vector (A2 and A3, respectively).
In the absence of the neutral (2-wire two-phase):
