Vapor-phase drying in the transformer tank
For vapor-phase drying in the transformer tank, you have to open the kero-
sene drain plug before drying so that the kerosene condensate can drain
from the oil compartment.
The kerosene drain plug is located in the oil compartment base and is not
generally accessible from the outside. For this reason, you first have to re-
move the diverter switch insert, open the kerosene drain plug, and then in-
stall the diverter switch insert again. After the drying process, you have to re-
move the diverter switch insert again to close the kerosene drain plug.
If you have already opened the kerosene drain plug in the transformer for
vapor-phase drying in the transformer tank when installing the on-load tap-
changer, you can start the drying operation directly.
Removing diverter switch insert
Proceed as follows to remove the diverter switch insert.
