It may be a good idea to move the on-load tap-changer into a position other
than the mid-position. This allows you to reduce the voltage differences be-
tween the grids to be connected and thereby minimize the inrush current im-
pulse.
2. On the control unit, set the desired operating mode by pressing the corre-
sponding key:
- Auto mode: AVR AUTO
- Manual mode: AVR MANUAL
- Control via remote connection: EXTERNAL CONTROL.
3. Switch on the low-voltage busbar.
4. Once the transformer has been switched on, ensure that the inrush cur-
rent impulse has subsided.
ð
On-load tap-change operations can now be undertaken both when idling
and under load conditions.
