Cambridge Sensotec has introduced the Rapidox 3100-C IR SF6 analyser, designed to provide improved accuracy, stability and response time when measuring SF6.
Regular checking of SF6 gas insulated substations allows the user to run fault preventative maintenance programmes, which can increase the lifecycle of SF6 gas.
In addition to measuring SF6, the Rapidox 3100-C IR SF6 analyser also monitors SO2 (0-100ppm) and H2O (-100Cdp to +20Cdp).
Evaluating the moisture content of SF6 is important when monitoring the dielectric strength of the gas.
SO2 measurements are vital as the decomposition products of Sf6 can be identified by analysing the SO2 content of the gas, which is a product of the breakdown of SOF2 and SOF4 after an electrical discharge.
All three gases are monitored simultaneously and the bespoke software supplied with each Rapidox unit provides continuous data logging.
The Rapidox 3100-C SF6 IR analyser also includes internal data logging at a rate set by the user for later downloading to a PC.
The unit will retain the internally logged data even when powered down.
The analyser is fitted with a gas output nozzle that allows all sampled gas to be recovered and recycled, ensuring that no SF6 gas is released into the atmosphere in accordance with the Kyoto treaty.
The analyser can be supplied as a bench-mounted instrument or as a full kit in a transport suitcase, with a range of DILO compatible sampling hoses, couplings and a thermal printer.
Cambridge Sensotec also provides low-cost SF6 gas recovery bags to ensure no gas escapes into the atmosphere when using the Rapidox 3100-C IR SF6 analyser.
