Voltage measuring/voltage monitoring Ph-neut./Ph-Ph
Ph-neut/Ph-neut The electrical system(generator, busbar, and mains) consists of
the three phase conductors and a neutral conductor. Thus the N
lug (terminal 0) must be connected.
The phase-phase conductor voltages and the phase-neutral vol-
tages are shown in the display.
The voltage monitoring entries are referred to the phase-neutral
voltages (V
L-N
).
Ph-neut/Ph-Ph The electrical system(generator, busbar, and mains) consists of
the three phase conductors and a neutral conductor. Thus the N
lug (terminal 0) must be connected.
The phase-phase conductor voltages and the phase-neutral vol-
tages are shown in the display.
The voltage monitoring entries are referred to the phase-phase
voltages (V
L-L
).
Ph-Ph/Ph-Ph The electrical system(generator, busbar, and mains) consists only
of the three phase conductors (without neutral conductor). Thus
the N lug (terminal 0) cannot be connected.
Only the phase conductor voltages are shown in the display.
The voltage monitoring entries are referred to the phase-phase
voltages (V
L-L
).
NOTE
Terminal 0 must be isolated for the setting 'Ph-Ph/Ph-Ph' (voltage measuring Ph-Ph, voltage monitoring
Ph-Ph) since a contact voltage in inadmissible range may occur at terminal 0.
