Gas Analyser in development will offer pump back facility for measuring SF6 within high voltage Gas Insulated Switchgear

Listen to this article

Cambridge Sensotec is developing an all new SF6 gas analyser with pump back facility for measuring SF6 within high voltage Gas Insulated Switchgear (GIS).
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 handing 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 in order to assess the applications requirements in full.

SF6 Gas Analysis

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.
