10.8 Removing the bushing adapter and bushing coupling unit
CAUTION
Fire hazard!
If you commission the transformer and the bushing's test tap is not
grounded, depending on the type of bushing, there is a risk that the bushing
will be destroyed and the transformer will catch fire.
► Observe the operating instructions for the bushing.
► Only commission the transformer if the cap for the bushing test tap is fit-
ted or if the bushing adapter and bushing coupling unit are fitted and con-
nected.
If you remove the bushing coupling unit and bushing adapter correctly, you
can then put the transformer back into operation.
Proceed as follows to remove the bushing coupling unit and the bushing
adapter:
1. Remove the connection cable between the control cabinet and bushing
coupling unit.
2. Install the cover cap for the U connection of the bushing coupling unit.
3. Remove the connection cable between the bushing coupling unit and the
bushing adapter.
4. Remove the grounding cable between the transformer and the supporting
plate of the bushing coupling unit.
5. Unscrew the fixing screw on the bushing flange and remove the bushing
coupling unit together with the supporting plate.
6. Install the fixing screw on the bushing flange in accordance with the oper-
ating instructions from the bushing manufacturer.
7. Remove the bushing adapter.
8.
CAUTION!
Install the cap onto the bushing test tap. While doing so,
follow the notes in the operating instructions from the bushing manufac-
turer. Otherwise the bushing may be damaged.
