Answer Posted / hannes zorro
The phase-to-phase voltage is the voltage between the 3
phases. Line-to-line voltage is the same as phase to phase
voltage. Both are better know as the "line voltage".
The phase to neatral is the voltage between one phase and
the neatral. This is better know as the phase voltage.
Example: for a balance 3 phase 415 line voltage system, the
phase voltage is 240V (415/sq(3)). Thus, the line-to-line
is 415V and the phase to phase is 415V. The phase voltage
is 240V and the phase to neatral is 240V.
