5.3.8 Filling the oil compartment of the on-load tap-changer with
insulating fluid
NOTICE
Damage to the on-load tap-changer!
Unsuitable insulating fluids cause damage to the on-load tap-changer.
► Use insulating fluids that meet the requirements in accordance with IEC
60296.
► If approved by the transformer manufacturer, you can use synthetic es-
ters in accordance with IEC 61099 approved by Maschinenfabrik Rein-
hausen GmbH.
After drying, completely fill the oil compartment (diverter switch insert fitted)
with oil again as soon as possible so that an impermissible amount of humid-
ity is not absorbed from the surroundings.
1. Establish a connecting lead between pipe connection E2 and one of the
pipe connections R, S or Q to ensure equal pressure in the oil compart-
ment and transformer during evacuation.
