Rapidox SF₆ - SO₂ - H₂O analyser

SF₆ is a man-made gas used in high-voltage switchgear because of its great arc quenching capabilities. Partial discharges and leaks over time eventually cause the SF₆ to decompose into highly corrosive compounds. It is therefore essential to monitor the condition of the SF₆ to protect the equipment from spark damage and corrosion.

The Rapidox 3100-C IR SF₆ analyser is a multi-gas analyser for the simultaneous measurement of SF₆ (0-100%), SO₂ (0-100ppm) and H₂O dew-point (-100°C to + 20°C). This instrument is designed for controlling and monitoring the quality of SF₆ in gas insulated sub-stations and circuit breakers. The multi-gas analyser not only measures the SF₆ gas content in air or nitrogen over the full range, but also measures the moisture content of the SF₆ which is essential when monitoring the dielectric strength of the gas.

The decomposition products of SF6 can be identified by analysing the SO2 content of the gas; this forms from

the breakdown of SOF2 and SOF4 after an electrical discharge. The analyser incorporates

an electrochemical SO2 sensor to measure ppm levels of sulfur dioxide. All three

gases can be monitored and data-logged simultaneously and just a few minutes are

required to get a stable reading.

Regular checking of SF6 gas insulated substations allows fault preventative maintenance

programs to be implemented, and increases the life cycle of the SF6.

The analyser has a gas output nozzle allowing all sampled gas to be recovered and

recycled, ensuring that no SF6 gas is released into the atmosphere (in accordance with

the Kyoto agreement).
