calculation
Calculate the SF
6
gas filling pressure in accordance with the temperature and
the local atmospheric pressure.
Filling is carried out to calculated pressure plus 0.
01 MPa.
See the module “SF

Step Action Comment
1 Open the SF
6
gas bottle tap (7
)
and adjust gas output by acting o
n
the cock (9) of the pressur
e
reducer (reduced flow rate).
Close the tap (7) from time to
time to check pressure on the
gauge (11).
2 Start filling again until the
required pressure is reached.
3 Close in this order : the tap (7),
then the cock (9).
