Pipe connection E2
Pipe connection E2 is sealed off with a blank cover. It leads into the oil tank
of the transformer, directly under the on-load tap-changer head and can be
connected to a collective pipe for the Buchholz relay, if necessary. This pipe
connection serves a further purpose, namely to equalize the pressure be-
tween the transformer tank and oil compartment of the on-load tap-changer,
which is necessary for drying, filling with insulating fluid and transportation of
the transformer.
