Figure 7-6 Device setting "USE PTs?"
Procedure
1. In the "SETTINGS" menu, call the "BASIC PARAMETERS" entry.
2. In the "BASIC PARAMETERS" menu, open the "VOLTAGE INPUTS" entry:
<F4>
The display shows the current settings.
If the "PT PRIMARY" and "PT SECONDARY" fields are not visible, direct measurement
on the system is set. Switch from direct measurement to measurement using voltage
transducers. You can find the instructions for this in the "Measurement using voltage
transducers" chapter.
3. Go to the "PT PRIMARY" device setting:
<F2> or <F3>
4. Open edit mode of the "PT PRIMARY" device setting:
<F4>
5. Set the desired value:
<F2> or <F3>
6. Accept the value:
<F4>
The value of the primary voltage is permanently saved and becomes effective
immediately.
The display returns to display mode.
7. Go to the "PT SECONDARY" device setting:
<F2> or <F3>
Proceed in exactly the same way as when entering the primary voltage.
The value of the secondary voltage is permanently saved and becomes effective
immediately.
The display returns to display mode.
8. Return to one of the selection menus or to the measured values display:
<F1>
Example:
You want to measure using voltage transducers for 10000 V/100 V on a 10 kV system.
For this purpose, enter:
1.
USE PTs?: On:
2. PT PRIMARY: 10000V
3. PT SECONDARY: 100V
