Clean Air and Oxygen in SF₆-Free Switchgear: Monitoring at CHP During the SF₆ Transition
New dry-air (Clean Air) switchgear at CHP plants needs O₂, humidity and purity control. Rapidox 6100 Clean Air Pumpback for mixed SF₆ and SF₆-free fleets.
EN version — draft. Ready to publish once kk/en routing (i18n) is implemented across the site.
Utilities are migrating MV switchgear to SF₆-free Clean Air insulation. On a single CHP plant, legacy SF₆ cells and new dry-air cubicles coexist for years — one analyser fleet is preferable to two.
Rapidox 6100 Clean Air Pumpback measures both SF₆ and dry air with pump-back (zero emission sampling). For Clean Air, oxygen and dew point are primary indicators; O₂ drift with stable pressure signals seal problems or incorrect nitrogen commissioning.
Typical CHP rollout: fleet audit → baseline records per cell → one 6100 + Hose Kit → align with SF₆ test procedure and PD ultrasound.
Before confined entry, check O₂ — see oxygen displacement in GIS. Scope: thermal power plants; not oil & gas.
