Pure SF<sub>6<\/sub> is the standard filling within GIS, but over time gas compartments become contaminated with water vapor (H<sub>2<\/sub>O) through permeation and by desorption from internal materials. Whilst water vapor and SF<sub>6<\/sub> do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur and fluorine from SF<sub>6<\/sub> to form decomposition by-products. These include sulfur dioxide (SO<sub>2<\/sub>) and hydrofluoric acid (HF) that are corrosive to the internal components of gas compartments.<\/p>\n<p>SF<sub>6<\/sub> with low water vapor content (low humidity) significantly reduces the potential for formation of these corrosive compounds, which is why accurate and repeatable measurement data is an invaluable part of any GIS preventative maintenance program.<\/p>\n<p>The 973-SF6 gas analyzer is supplied as a complete set that includes:<\/p>\n<ul>\n<li>973-SF<sub>6 <\/sub>Instrument<\/li>\n<li>Transport Peli-Case 1620<\/li>\n<li>6 m Stainless Steel armored PTFE tubing<\/li>\n<li>SF<sub>6 <\/sub>coupling DN8 with quick coupling (Rectus)<\/li>\n<li>SF<sub>6 <\/sub>coupling DN20 with quick coupling (Rectus)<\/li>\n<li>90\u00b0 Angle for Rectus-Coupling<\/li>\n<li>Serial cable DB9 3m 1:1 male\/female<\/li>\n<li>RS-232 \/ USB Adapter<\/li>\n<li>USB stick with 973-SF<sub>6  <\/sub>Software and operation manuals<\/li>\n<li>Power cable (country specific)<\/li>\n<li>Hex key for SO<sub>2 <\/sub>module<\/li>\n<li>SO<sub>2 <\/sub>Dummy sensor<\/li>\n<li>Cotton swabs, sterile (10 pieces)<\/li>\n<li>Operation Manual (2 pieces)<\/li>\n<li>Calibration Certificate<\/li>\n<\/ul>\n<p>All accessories can also be ordered separately to replace damaged or missing components.<\/p>\n<\/div>\n<\/div>\n<div id=\"affix-navigation\" class=\"mbw-extended-page-header-meta-affix mbw-desktop-only\">\n<ul>\n<li>Features<\/li>\n<li>Key Specifications<\/li>\n<li>Typical Applications<\/li>\n<li>Accessories &amp; Spare Parts<\/li>\n<li>Downloads<\/li>\n<li>Media<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/header>\n<section id=\"Features-0\"><strong>Features<\/strong><\/p>\n<div>\n<ul>\n<li>Simultaneous measurement of humidity, SF<sub>6<\/sub> purity and SO<sub>2<\/sub> concentration<\/li>\n<li>Integrated gas recovery system with automatic pump back<\/li>\n<li>Fully automated SF<sub>6<\/sub> gas testing<\/li>\n<li>Fundamental drift-free measuring principle<\/li>\n<li>Measurement results at SF<sub>6<\/sub> compartment or standard pressure<\/li>\n<li>Intuitive color touch screen user Interface<\/li>\n<li>User verifiable calibration<\/li>\n<li>Robust case for easy transportation<\/li>\n<\/ul>\n<\/div>\n<\/section>\n<section id=\"Key Specifications-1\"><strong>Key Specifications<\/strong><\/p>\n<div>\n<section id=\"key-specifications\">\n<div>\n<ul>\n<li>Frost\/dew Point range: -50\u2026+20 \u00b0C<\/li>\n<li>Volume SF<sub>6<\/sub> range: 80\u2026100%<\/li>\n<li>Inlet pressure range: 120\u20261\u2019000 kPa abs.<\/li>\n<li>Frost\/dew point accuracy: \u00b1 0.5 \u00b0C<\/li>\n<li>ppmv \/ppmw accuracy: \u00b1 1 ppm +6% of reading<\/li>\n<li>Volume SF<sub>6<\/sub> accuracy: \u00b1 0.5%<\/li>\n<li>Pressure accuracy: \u00b1 3 kPa<\/li>\n<\/ul>\n<\/div>\n<\/section>\n<section id=\"typical-applications\"><\/section>\n<\/div>\n<\/section>\n<section id=\"Typical Applications-2\"><strong>Typical Applications<\/strong><\/p>\n<div>\n<ul>\n<li>Electrical Power Utilities<\/li>\n<li>Gas insulated switchgear<\/li>\n<li>SF<sub>6<\/sub> gas manufacturers and suppliers<\/li>\n<\/ul>\n<\/div>\n<\/section>\n<p>&nbsp;<\/p>\n<section id=\"Typical Applications-2\"><div class='w3eden'><!-- WPDM Link Template: Default Template -->\n\n<div class=\"link-template-default card mb-2\">\n    <div class=\"card-body\">\n        <div class=\"media\">\n            <div class=\"mr-3 img-48\"><img decoding=\"async\" class=\"wpdm_icon\" alt=\"Icon\"   src=\"http:\/\/testnordic.com\/wp-content\/plugins\/download-manager\/assets\/file-type-icons\/pdf.png\" \/><\/div>\n            <div class=\"media-body\">\n                <h3 class=\"package-title\"><a href='https:\/\/testnordic.se\/en\/download\/973-sf6-gas-analyzer\/'>973-SF6 Gas Analyzer<\/a><\/h3>\n                <div class=\"text-muted text-small\"><i class=\"fas fa-copy\"><\/i> 1 file(s) <i class=\"fas fa-hdd ml-3\"><\/i> 3.25 MB<\/div>\n            <\/div>\n            <div class=\"ml-3\">\n                <a class='wpdm-download-link download-on-click btn btn-primary ' rel='nofollow' href='#' data-downloadurl=\"https:\/\/testnordic.se\/en\/download\/973-sf6-gas-analyzer\/?wpdmdl=3235&refresh=6a7306a146d1c1785923233\">Download<\/a>\n            <\/div>\n        <\/div>\n    <\/div>\n<\/div>\n\n<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"<p>The 973-SF<sub>6<\/sub> is an advanced SF<sub>6<\/sub> gas analyzer for the measurement of humidity, SF<sub>6<\/sub> purity and SO<sub>2<\/sub> concentration in SF<sub>6<\/sub> gas insulated switchgears (GIS) and other high voltage equipment.
