SF6 gas and its use within high voltage applications - Part 2

High precision infrared (IR) sensor technology is used by the Rapidox for the analysis of SF6 gas. Infrared sensor technology is based upon the principle that some gases absorb IR radiation at specific wavelengths. It is advantageous in that it supplies the user with a rapid response, is immune to poisoning and contamination and has the ability to operate in the absence of oxygen.

Decomposition products sulphur dioxide (SO2) and moisture (H2O) may also be measured by the Rapidox SF6 6100 gas analyser, using electrochemical and advanced ceramic sensor technology respectively. Additional sensors for gases such as carbon monoxide (CO), hydrogen sulphide (H2S) and hydrogen fluoride (HF) are also available.

Cambridge Sensotec has also been carrying out field tests, which have highlighted the requirement for quick and easy to use instruments for onsite SF6 gas maintenance procedures. Therefore the Rapidox SF6 6100 pump back gas analyser has been developed with an inbuilt microprocessor operated by a 7” colour touchscreen, with the ability to store 12 months of continuous data. Pre-loaded IEC and CIGRE tests are available, alongside the ability to customise test parameters. Housed within a robust IP66 Peli case, the Rapidox is lightweight and features an 8 hour lithium ion battery in addition to an in-built printer, making it a truly portable field instrument.

Due for release in Autumn 2014, the Rapidox SF6 6100 pump back gas analyser is to be showcased in October 2014 at the EP China exhibition: http://www.epchinashow.com.
