2. Design and function / 3. Safety
Optional recalibration valve
With regard to switchgear safety, asset protection and environmental protection, it is
common to perform functional checks of the measuring instruments on a regular basis.
Article 5 of EU regulation No. 517/2014 on fluorinated greenhouse gases, provides
EN
for checking of the leakage detection system at least every 6 years if it contains
more than 22 kg SF₆ gas and the plant was commissioned after 01 January 2017.
With the help of the optional, permanently welded recalibration valve, the gas density
monitor can be shut off from the process and recalibrated without having to disassemble
it. This not only reduces maintenance time but also minimises the risks of SF₆ gas
emissions and potential leakages during recommissioning.
When connecting a test instrument (e.g. model ACS-10 or model BCS-10) to the
recalibration valve, the gas density monitor is automatically disconnected from the gas
compartment and a recalibration can be performed. The test instrument can then be
disconnected from the recalibration valve and the connection to the gas compartment is
re-established automatically.
The recalibration valve is also available as a retrofit solution for gas density monitors
and other leakage detection systems already installed in the field, as model GLTC-CV,
and can be mounted between the gas compartment and gas density monitor.
