Woodward LS-5 v2 Series - Page 89

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
1Ph 3W Measurement is performed Line-
Neutral (WYE connected system) and
Line-Line (Delta connected system).
The protection depends on the setting
of parameter 1771.
Measurement, display, and protection
are adjusted according to the rules for
single-phase systems.
Monitoring refers to the following
voltages:
• VL13 (parameter 1771
con󰈡gured to "Phase-phase")
• VL1N, VL3N (parameter 1771
con󰈡gured to "Phase-neutral")
• VL1N, VL3N (parameter 1771
con󰈡gured to "All")
Notes
If this parameter is con󰈡gured to 1Ph
3W, the system A rated voltages
(parameters 1766 must be entered as
Line-Line (Delta).

principles refer to ╚═▷ “3.3.4.2
System A Voltage”.
1850 SyA. current measuring 2 [L1 L2 L3 ] All three phases are monitored.
Measurement, display and protection
are adjusted according to the rules for
3-phase measurement. Monitoring
refers to the following currents: IL1,
IL2, IL3
Phase L{1/2/3} Only one phase is monitored.
