are adjusted according to the rules for
single-phase measurement.
Monitoring refers to the selected
phase.
Notes
This parameter is only e󰈠ective if
system A voltage measuring
(parameter 1851) is con󰈡gured to
"3Ph 4W" or "3Ph 3W".
For information on measuring
principles refer to ╚═▷ “3.3.4.2
System A Voltage”.
1853 SyB. voltage measuring 2 [3Ph 4W] Measurement is performed Line-
Neutral (WYE connected system) and
Line-Line (Delta connected system).
The protection depends on the setting
of parameter 1770.
Phase voltages and the neutral must
be connected for proper calculation.
Measurement, display and protection
are adjusted according to the rules for
WYE connected systems.
Monitoring refers to the following
voltages:
• VL12, VL23 and VL31 (parameter
1770 con󰈡gured to "Phase-
phase")
•
VL1N, VL2N and VL3N
(parameter
1770 con󰈡gured to
"Phase-neutral")
3Ph 3W Measurement is performed Line-Line
(Delta connected system). Phase
voltages must be connected for
proper calculation.
Measurement, display and protection
are adjusted according to the rules for
Delta connected systems.
Monitoring refers to the following
voltages:
• VL12, VL23, VL31
1Ph 2W Measurement is performed Line-
Neutral (WYE connected system) if
parameter 1858 is con󰈡gured to
"Phase - neutral" and Line-Line (Delta
connected system) if parameter 1858
is con󰈡gured to "Phase - phase".
Measurement, display and protection
are adjusted according to the rules for
phase-phase systems.
Monitoring refers to the following
voltages:
• VL1N, VL12
