GCTU-M SF6 Analyser (Mains/AC Operated)

The SF6 Analyser GCTU-M manufactured by Alpha Moisture Systems has been specifically developed to collect all SF6 sampled for analysis.
GCTU-M is also designed to recycle (pump-back) the entire SF6 sample to a HV/MV gas insulated switchgear (GIS)/transformer or circuit breaker.
This ensures a zero effect to the installation and protects the environment by eliminating any discharge of SF6 to the atmosphere.
The common usage of SF6 in HV/MV switchgear, transformers and circuit breakers has brought significant advantages in performance and reliabillity.
However, because SF6 is a "greenhouse gas", special precautions must be adopted when routine sample analysis is undertaken.
