Calculation of the
filling pressure
Calculate the SF
6
gas pressure as a function of the local atmospheric
pressure and temperature.
The filling takes place at the calculated pressure, increaed by 0.01 MPa
.
See module ”Monitoring SF

Step Action Remark
1 Open the tap (7) on the SF
6
cylinder and adjust the gas outlet
using the reducing valve (9) (low
rate of flow).
From time to time, close the
tap (7) to read the pressure
on the pressure gauge (11).
2 Resume filling until the desired
pressure is reached.
3 Close the tap (7) and the valve
(9) in that order.
