1. Go to
Settings > Calibrate hardware > Tap position (automatic)
.
2. Select the
Synchronize
button.
3. Press the
Start
button to confirm the message.
ð
The on-load tap changers are switched into the lower final position (the
lowest or the highest tap position, depending on the drive configura-
tion). Once the final position has been reached, a message with the
current tap position will appear.
4. Through the inspection window, check whether all on-load tap-changers
are in the same tap position as indicated in the message text.
5. If the tap positions are the same, press the
Yes
button to confirm the mes-
sage. Otherwise, press the
Cancel
button and follow the instructions in
Section 10.1, Page 310] chapter.
ð
The on-load tap changers are switched into the upper final position (the
highest or the lowest tap position depending on the drive configuration).
ð
Automatic synchronization is complete.
9.20 Line drop compensation
You can use the compensation function to compensate for the load-depen-
dent voltage drop between the transformer and consumer. The device pro-
vides 2 methods of compensation for this purpose:
▪ R&X compensation
▪ Z compensation
9.20.1 R&X compensation
R&X compensation can compensate for voltage losses on the lines and
therefore ensure correct voltage on the consumer. This requires precise line
data. After you have entered all of the line data, the device automatically cal-
culates the ohmic and inductive voltage drop and takes this into account for
automatic voltage regulation.
