1Ph 3W Measurement is performed Line-
Neutral (WYE connected system) and
Line-Line (Delta connected system).
The protection depends on the setting
of parameter
1770. Measurement,
display, and protection are adjusted
according to the rules for single-phase
systems.
Monitoring refers to the following
voltages:
• VL13 (parameter 1770
congured to "Phase-phase")
• VL1N, VL3N (parameter 1770
congured to "Phase-neutral")
Notes
If this parameter is congured to 1Ph
3W, the system B rated voltages
(parameter 1768) must be entered as
Line-Line (Delta).
For information on measuring
principles refer to ╚═▷ “3.3.4.2
System A Voltage”.
1852 SyB. current measuring 2 [Phase L1 ] Phase L1 is monitored. Measurement,
display and protection are adjusted
according to the rules for single-phase
measurement. Monitoring refers to
current I L1.
Phase L2 Phase L2 is monitored. Measurement,
display and protection are adjusted
according to the rules for single-phase
measurement. Monitoring refers to
current I L2.
Phase L3 Phase L3 is monitored. Measurement,
display and protection are adjusted
according to the rules for single-phase
measurement. Monitoring refers to
current I L3.
Notes
This parameter is only eective if
system B voltage measuring
(parameter 1853) is congured to
"3Ph 4W" or "3Ph 3W".
For information on measuring
principles refer to ╚═▷ “3.3.4.2
System A Voltage”.

Congure Transformer
General notes
This controller is available in two dierent hardware versions with either 1A [../1] or 5A
[../5] current transformer inputs. The setpoints for specic current parameters will dier
depending upon the hardware version, indicated on the data plate.
