7.5.3 Regulation mode
If you are measuring the voltage and current with the 3-phase UI 3 measur-
ing module, you can use this parameter to set whether you want 1-phase
voltage regulation or voltage regulation to the average value of the 3 phases.
You can select the following options:
▪ Single-phase: Voltage is automatically regulated to one selected phase.
Limit value monitoring, line drop compensation, and parallel operation
also take place on the selected phase using the circulating reactive cur-
rent minimization method.
▪ Average value regulation: Voltage is automatically regulated to the aver-
age of the 3 phases. Limit value monitoring, line drop compensation, and
parallel operation also take place using the circulating reactive current
minimization method to the average of the 3 phases.
If you activate the average value regulation option, automatic voltage regu-
lation is blocked should the voltage or current measurement of one of the 3
phases fail.
To set the regulation mode, proceed as follows:
1. Go to
Settings > Parameters > Measurement > Regulation mode
.
2. Select the option you want.
3. Press the
Accept
button to save the modified parameter.
7.5.4 Setting the display for the power factor
This parameter lets you set whether the device is to display a negative
power factor. You can select the following options:
Option
Description
Off
The power factor is always shown as positive.
P > 0
The power factor is shown as negative if the active power is
positive.
P < 0
The power factor is shown as negative if the active power is
negative.
Q > 0
The power factor is shown as negative if the reactive power is
positive.
Q < 0
The power factor is shown as negative if the reactive power is
negative.
Table 41: Setting the display for the power factor
To set the power factor display, proceed as follows:
1. Go to
Settings > Parameters > Measurement > Negative power factor
display
.
2. Select the desired option.
3. Press the
Accept
button to save the modified parameter.
