Over\u00adall, these mea\u00adsures make our sys\u00adtems around 20 per\u00adcent larg\u00ader, but oth\u00ader\u00adwise all func\u00adtion\u00adal\u00adi\u00adties remain the same,\u201d says Gabler. As more and more GIS man\u00adu\u00adfac\u00adtur\u00aders are also increas\u00ading\u00adly rely\u00ading on syn\u00adthet\u00adic air, HIGHVOLT\u2019s sys\u00adtems are com\u00adpat\u00adi\u00adble with them. How\u00adev\u00ader, exist\u00ading sys\u00adtems that are still oper\u00adat\u00aded with SF6<\/sub> can also con\u00adtin\u00adue to be test\u00aded if appro\u00adpri\u00adate adapters are used. \u201cOur sys\u00adtems are very flex\u00adi\u00adble in this respect,\u201d empha\u00adsizes Gabler. <\/p>\n\n\n\nIn addi\u00adtion to the envi\u00adron\u00admen\u00adtal aspect, syn\u00adthet\u00adic air also has oth\u00ader advan\u00adtages for oper\u00ada\u00adtors such as much eas\u00adi\u00ader gas han\u00addling. As Gabler explains: \u201cMain\u00adte\u00adnance is much more com\u00adplex with SF6<\/sub> because the gas has to be extract\u00aded at great expense and a num\u00adber of safe\u00adty pre\u00adcau\u00adtions are also nec\u00ades\u00adsary, for exam\u00adple dur\u00ading trans\u00adport \u2013 all of this is elim\u00adi\u00adnat\u00aded or sim\u00adpli\u00adfied with syn\u00adthet\u00adic air.\u201d The require\u00adments for syn\u00adthet\u00adic air are also less strict, and syn\u00adthet\u00adic air is more read\u00adi\u00adly avail\u00adable and sig\u00adnif\u00adi\u00adcant\u00adly cheap\u00ader than SF6<\/sub>. <\/p>\n\n\n\nThe HIGHVOLT engi\u00adneers have already adapt\u00aded the first res\u00ado\u00adnant reac\u00adtor coil for its AC volt\u00adage test sys\u00adtems to the new insu\u00adlat\u00ading medi\u00adum. \u201cThis means we are cur\u00adrent\u00adly one of the first man\u00adu\u00adfac\u00adtur\u00aders to bring test\u00ading tech\u00adnol\u00ado\u00adgy with syn\u00adthet\u00adic air onto the mar\u00adket.\u201d Fur\u00adther test\u00ading and mea\u00adsur\u00ading sys\u00adtems will grad\u00adu\u00adal\u00adly fol\u00adlow so that all HIGHVOLT prod\u00aduct series will be able to oper\u00adate with syn\u00adthet\u00adic air from 2028 onwards. .<\/p>\n\n\n\n

Challenge<\/h2>\n\n\n\n
Sul\u00adphur hexa\u00adflu\u00ado\u00adride (SF6<\/sub>) is an ide\u00adal insu\u00adlat\u00ading gas for gas-insu\u00adlat\u00aded switchgear (GIS) sys\u00adtems, which con\u00adtrol the flow of ener\u00adgy in sub\u00adsta\u00adtions or indus\u00adtri\u00adal plants, switch off cir\u00adcuits when required and pro\u00adtect the high-volt\u00adage grid from over\u00adloads. Com\u00adpared to out\u00addoor switchgear, GIS sys\u00adtems take up sig\u00adnif\u00adi\u00adcant\u00adly less space and are there\u00adfore par\u00adtic\u00adu\u00adlar\u00adly suit\u00adable for use in urban areas. And thanks to the out\u00adstand\u00ading prop\u00ader\u00adties of SF6<\/sub>, very com\u00adpact designs are pos\u00adsi\u00adble. How\u00adev\u00ader, this pop\u00adu\u00adlar insu\u00adlat\u00ading gas has a seri\u00adous dis\u00adad\u00advan\u00adtage: a cat\u00ada\u00adstroph\u00adic cli\u00admate foot\u00adprint. It is around 23,500 times more harm\u00adful to the cli\u00admate than CO\u00b2<\/sub> and remains in the atmos\u00adphere for 3,200 years. <\/p>\n<\/div><\/div>\n\n\n\n SF6<\/sub> remains in the atmos\u00adphere.<\/p>\n<\/div>\n\n\n\n is the per\u00adfect insu\u00adlat\u00ading gas for elec\u00adtri\u00adcal appli\u00adca\u00adtions thanks to its excel\u00adlent insu\u00adlat\u00ading prop\u00ader\u00adties.<\/p>\n<\/div>\n\n\n\n more harm\u00adful to the cli\u00admate than CO2<\/sub><\/p>\n<\/div>\n<\/div>\n\n\n\n In 2024, a new F\u2011gas reg\u00adu\u00adla\u00adtion there\u00adfore came into force in the EU, which increas\u00ading\u00adly restricts the use of flu\u00ado\u00adri\u00adnat\u00aded gas\u00ades and com\u00adplete\u00adly bans SF6<\/sub> gas in new elec\u00adtri\u00adcal instal\u00adla\u00adtions start\u00ading from 2032. This also affects HIGHVOLT\u2019s gas-insu\u00adlat\u00aded test\u00ading and mea\u00adsur\u00ading sys\u00adtems, which man\u00adu\u00adfac\u00adtur\u00aders and oper\u00ada\u00adtors need to test GIS sys\u00adtems. Dr. Tobias Gabler from HIGHVOLT explains: \u201cThe chal\u00adlenge is that there is no oth\u00ader gas that has sim\u00adi\u00adlar\u00adly good prop\u00ader\u00adties to SF6<\/sub>.\u201d Although there are already alter\u00adna\u00adtives on the mar\u00adket that have a sig\u00adnif\u00adi\u00adcant\u00adly bet\u00adter car\u00adbon foot\u00adprint, some of them also con\u00adtain flu\u00ado\u00adri\u00adnat\u00aded gas\u00ades, which the EU also wants to ban. \u201cWe want\u00aded a future-proof solu\u00adtion for our sys\u00adtems. We want our cus\u00adtomers to be able to rely on the assur\u00adance that they will still be able to use their test\u00ading sys\u00adtems in ten years\u2019 time,\u201d explains Gabler. <\/p>\n\n\n\n So, what is the alter\u00adna\u00adtive? The answer sounds very sim\u00adple: syn\u00adthet\u00adic air. It con\u00adsists of nitro\u00adgen and oxy\u00adgen, has a glob\u00adal warm\u00ading poten\u00adtial of zero and is there\u00adfore com\u00adplete\u00adly harm\u00adless to the cli\u00admate. The catch: syn\u00adthet\u00adic air has sig\u00adnif\u00adi\u00adcant\u00adly poor\u00ader insu\u00adlat\u00ading prop\u00ader\u00adties and can\u00adnot replace SF6<\/sub> gas on a one-to-one basis. \u201cHow\u00adev\u00ader, the dis\u00adad\u00advan\u00adtages can be over\u00adcome if we revise the design of our test\u00ading and mea\u00adsur\u00ading sys\u00adtems,\u201d explains Gabler. The test\u00ading experts at HIGHVOLT are there\u00adfore grad\u00adu\u00adal\u00adly scru\u00adti\u00adniz\u00ading all mea\u00adsur\u00ading and test\u00ading sys\u00adtems and inves\u00adti\u00adgat\u00ading how they can adapt the com\u00adpo\u00adnents to the new require\u00adments. For exam\u00adple, the insu\u00adlat\u00ading capac\u00adi\u00adty of syn\u00adthet\u00adic air can be sig\u00adnif\u00adi\u00adcant\u00adly improved by almost dou\u00adbling the oper\u00adat\u00ading pres\u00adsure in the sys\u00adtems from four to sev\u00aden bar. This in turn requires thick\u00ader walls for the ves\u00adsels so that they can with\u00adstand the high\u00ader pres\u00adsure. <\/p>\n\n\n\n <\/p>\n<\/div><\/div>\n\n\n\n Syn\u00adthet\u00adic air car\u00adries no risks which means that it can be used per\u00adma\u00adnent\u00adly regard\u00adless of future reg\u00adu\u00adla\u00adtions.<\/p>\n<\/div>\n\n\n\n con\u00adsists of nitro\u00adgen and oxy\u00adgen.<\/p>\n<\/div>\n\n\n\n Syn\u00adthet\u00adic air car\u00adries no risks which means that it can be used per\u00adma\u00adnent\u00adly regard\u00adless of future reg\u00adu\u00adla\u00adtions.<\/p>\n<\/div>\n<\/div>\n\n\n\n \u201cWe also have to increase the insu\u00adla\u00adtion dis\u00adtances and adapt the elec\u00adtrode geome\u00adtries. Over\u00adall, these mea\u00adsures make our sys\u00adtems around 20 per\u00adcent larg\u00ader, but oth\u00ader\u00adwise all func\u00adtion\u00adal\u00adi\u00adties remain the same,\u201d says Gabler. As more and more GIS man\u00adu\u00adfac\u00adtur\u00aders are also increas\u00ading\u00adly rely\u00ading on syn\u00adthet\u00adic air, HIGHVOLT\u2019s sys\u00adtems are com\u00adpat\u00adi\u00adble with them.
