Product Description

DESCRIPTION
The SFA2000 SF6 is a fully-automatic zero-emissions SF6 gas analyser, designed for controlling and monitoring the quality and purity of gas used in high voltage switchgear, circuit breakers and transformers.
Exceptional accuracy and stability are provided when measuring the purity of SF 6 gas, through specially selected sensors. The modular configuration allows for up to eight compatible gases to be analysed, simultaneously, using one analyser. The SFA2000 is fully compatible with mixtures of SF6 , CF4 , N2 and air, together with toxic contamination gases such as SO2 , H2 , HF, H2S and CO. The unit also measures the water content of the gas in dewpoint or ppm to ensure dryness is acceptable.
The SFA2000 is housed neatly into a tough Peli transport case supplied with special tongue and groove self sealing couplings, which are compatible with famous brands. Once powered and connected, the SFA2000 automatically removes a small quantity of gas from the electrical equipment, controlled with an auto gas pressure sensing function. A vacuum purge cycle and internal gas storage system ensures that no air can
contaminate the gas sample and that no SF 6 gas is able to escape during the testing period. All measured gases are analysed and data-logged simultaneously with only a few minutes required to achieve a stable reading. A powerful 10 bar compressor, with a separate lithium battery power supply, then returns the gas to the electrical equipment at high pressure. Results are displayed on screen and printed using the inbuilt thermal printer. The SFA2000 has multiple safety features built in to ensure the cycle is completed correctly without gas loss or cross contamination.
The analyser is pre-programmed with all current IEC and CIGRE test configurations, with the ability to create customised test parameters.

SF 6 Gas
SF 6 is an extremely stable, non-flammable and highly electronegative gas with excellent dielectric properties. It is commonly used in medium and high-voltage electrical equipment as an electrical insulator, arc-quenching and cooling medium. However, SF 6 is classified as a greenhouse gas and must be kept within a closed circuit to avoid any deliberate release into the atmosphere. The international Kyoto agreement protocol has mandated reductions to harmful emissions amongst its member states. For the power transmission and distribution network, SF 6 technology remains essential. To protect personnel, equipment and the environment, regular SF 6 analysis should be adopted within the maintenance schedule. The early identification of any decomposition products and moisture within the SF 6 gas will help avoid unnecessary shutdowns, outages and failures, in addition to reducing maintenance expenditures.
