Cambridge Sensotec is Developing an All New SF6 Gas Analyser with Pump Back Facility

In response to the requirements of the electricity generation and distribution industries, Cambridge Sensotec is nearing completion of a new and exciting portable SF₆ gas analyser to include a gas return function.

As GIS equipment contains pressurised SF₆ gas, Cambridge Sensotec’s new analyser will allow the user to return the sample to pressurised switchgear. SF₆ gas samples can be extracted from the GIS equipment into the analyser, measured and pumped back. This eliminates the need to refill the GIS and prevents the release of any SF₆ gas into the atmosphere (in accordance with Kyoto greenhouse gas handling legislation).

As part of the product’s development, Cambridge Sensotec is conducting extensive on-site trials to gain technical and practical knowledge. The information gathered has then been fed into the product development process, meaning the completed unit will be designed to meet all of the challenges faced by the user. The site visits included a tour of a typical substation facility and demonstrations by the site staff of the procedures of testing GIS equipment. Cambridge Sensotec’s prototype SF₆ gas analyser was used in conjunction with both new and old GIS equipment to assess the applications requirements in full.

In addition to the analyser’s gas pump back facility, the portable analyser will include high precision gas sensors for measuring SF₆, SO₂ and H₂O, with the option of adding sensors for measuring HF and O2 within the SF₆ gas. The analyser will also feature a 7” touch screen display, pre-loaded IEC and CIGRE tests (custom tests can also be set), an 8 hour lithium ion battery, robust IP66 Peli-case, 12 months continuous data storage and optional DILO DN8 and DN20 fittings.

The launch date of the new SF₆ gas analyser is planned for Autumn 2014.
