When Rein\u00adhausen sub\u00adsidiary HIGHVOLT launched its HiMON\u00ae<\/sup> cable mon\u00adi\u00adtor\u00ading sys\u00adtem four years ago, hard\u00adly any\u00adone imag\u00adined the num\u00adber of appli\u00adca\u00adtions for which the tech\u00adnol\u00ado\u00adgy would ulti\u00admate\u00adly be suit\u00adable. HIGHVOLT ini\u00adtial\u00adly devel\u00adoped the solu\u00adtion to mon\u00adi\u00adtor the con\u00addi\u00adtion of kilo\u00adme\u00adters of HVDC under\u00adground cables \u2013 such as those in the S\u00fcdLink and S\u00fcdostLink pow\u00ader high\u00adways, which trans\u00adport wind pow\u00ader from north\u00adern Ger\u00admany to indus\u00adtri\u00adal cen\u00adters in the south. HiMON\u00ae<\/sup> proved its worth, and soon HIGHVOLT began receiv\u00ading inquiries from grid oper\u00ada\u00adtors and cable man\u00adu\u00adfac\u00adtur\u00aders ask\u00ading whether the tech\u00adnol\u00ado\u00adgy could also be used for AC cables, sub\u00adma\u00adrine cables, neu\u00adtral con\u00adduc\u00adtors, or over\u00adhead sys\u00adtems. At the same time, it became clear that cable mon\u00adi\u00adtor\u00ading involves more than just col\u00adlect\u00ading mea\u00adsure\u00adment data. Grid oper\u00ada\u00adtors need an intel\u00adli\u00adgent ear\u00adly-warn\u00ading sys\u00adtem that iden\u00adti\u00adfies risks, eval\u00adu\u00adates them, and pro\u00advides con\u00adcrete rec\u00adom\u00admen\u00adda\u00adtions for action. That is why HIGHVOLT engi\u00adneers con\u00adtin\u00adued to devel\u00adop the tech\u00adnol\u00ado\u00adgy in close col\u00adlab\u00ado\u00adra\u00adtion with cus\u00adtomers \u2013 evolv\u00ading it into a plat\u00adform that bun\u00addles sen\u00adsor tech\u00adnol\u00ado\u00adgy, data analy\u00adsis, expert eval\u00adu\u00ada\u00adtion, and ser\u00advices, and sup\u00adports cable sys\u00adtems through\u00adout their entire life\u00adcy\u00adcle.<\/p>\n\n\n\n

Before a cable leaves the fac\u00adto\u00adry, man\u00adu\u00adfac\u00adtur\u00aders inspect its con\u00addi\u00adtion imme\u00addi\u00adate\u00adly after pro\u00adduc\u00adtion. How is the insu\u00adla\u00adtion per\u00adform\u00ading? Are there signs of par\u00adtial dis\u00adcharges? And how do elec\u00adtri\u00adcal sig\u00adnals change as they trav\u00adel through the cable? HiMON\u00ae<\/sup> cap\u00adtures this infor\u00adma\u00adtion and uses it to cre\u00adate a tech\u00adni\u00adcal fin\u00adger\u00adprint which shows whether the cable pass\u00ades all tests and also serves as a ref\u00ader\u00adence for future oper\u00ada\u00adtion. This is extreme\u00adly valu\u00adable for grid oper\u00ada\u00adtors as they can then com\u00adpare the cable\u2019s cur\u00adrent con\u00addi\u00adtion with its base\u00adline val\u00adues at any time and detect devi\u00ada\u00adtions ear\u00adly on. The con\u00addi\u00adtion assess\u00adment thus begins even before com\u00admis\u00adsion\u00ading.<\/p>\n<\/div><\/div>\n\n\n\n

Once the cable has suc\u00adcess\u00adful\u00adly passed its tests, it is ready for instal\u00adla\u00adtion. It now becomes part of the pow\u00ader grid \u2013 and HiMON\u00ae<\/sup> along with it. Var\u00adi\u00adous sen\u00adsor types are installed along the cable route. HiMON\u00ae<\/sup> Blue, for exam\u00adple, is mount\u00aded at inter\u00advals of twelve kilo\u00adme\u00adters on the cable joints to detect even the small\u00adest par\u00adtial dis\u00adcharges. This allows the sys\u00adtem to detect and locate ear\u00adly signs of insu\u00adla\u00adtion dam\u00adage. HiMAG\u00ae<\/sup> Red, on the oth\u00ader hand, is locat\u00aded at the ends of the cable route. It mea\u00adsures sig\u00adnal pat\u00adterns that occur dur\u00ading a cable break\u00addown to deter\u00admine its exact loca\u00adtion. For grid oper\u00ada\u00adtors, this is a deci\u00adsive advan\u00adtage \u2013 pre\u00adcise fault loca\u00adtion saves them valu\u00adable time and high costs in an emer\u00adgency. After all, they not only know that dam\u00adage has occurred, but also exact\u00adly where.<\/p>\n<\/div><\/div>\n\n\n\n

Once the cable is con\u00adnect\u00aded and laid, its dai\u00adly life in the pow\u00ader grid begins. Whether buried under\u00adground or under\u00adwa\u00adter, the rav\u00adages of time now take their toll. Envi\u00adron\u00admen\u00adtal fac\u00adtors and pow\u00ader fluc\u00adtu\u00ada\u00adtions cause the cable to age and exac\u00ader\u00adbate even the small\u00adest weak\u00adness\u00ades that may have arisen dur\u00ading man\u00adu\u00adfac\u00adtur\u00ading or instal\u00adla\u00adtion \u2013 more so in some places, less in oth\u00aders. HiMON\u00ae<\/sup> reli\u00adably iden\u00adti\u00adfies which sec\u00adtions are par\u00adtic\u00adu\u00adlar\u00adly affect\u00aded and could become prob\u00adlem\u00adat\u00adic. To do this, the mon\u00adi\u00adtor\u00ading plat\u00adform con\u00adtin\u00adu\u00adous\u00adly col\u00adlects data, con\u00adsol\u00adi\u00addates it in the cloud, and com\u00adpares it with the cable\u2019s tech\u00adni\u00adcal fin\u00adger\u00adprint. This allows HiMON\u00ae<\/sup> to detect even the slight\u00adest changes and report poten\u00adtial weak points via a traf\u00adfic-light sys\u00adtem. Net\u00adwork oper\u00ada\u00adtors can thus iden\u00adti\u00adfy where a prob\u00adlem is devel\u00adop\u00ading ear\u00adly on, long before it becomes a prob\u00adlem. This makes cable main\u00adte\u00adnance more proac\u00adtive and gives net\u00adwork oper\u00ada\u00adtors sig\u00adnif\u00adi\u00adcant\u00adly more time to plan and imple\u00adment mea\u00adsures.<\/p>\n<\/div><\/div>\n\n\n\n

But what about the many cables that have been in use for decades? HiMON\u00ae<\/sup> is per\u00adfect for these too \u2013 because the tech\u00adnol\u00ado\u00adgy can be retro\u00adfit\u00adted. The cable doesn\u2019t even need to be cut open. The sen\u00adsors can sim\u00adply be wrapped around the cable. This way, HiMON\u00ae<\/sup> pro\u00advides valu\u00adable data for con\u00addi\u00adtion assess\u00adment even in old\u00ader indus\u00adtri\u00adal net\u00adworks. But that\u2019s not all. The mon\u00adi\u00adtor\u00ading plat\u00adform also includes HIGHVOLT\u2019s ser\u00advice and exper\u00adtise so that net\u00adwork oper\u00ada\u00adtors don\u2019t need to view or ana\u00adlyze the mea\u00adsure\u00adment data them\u00adselves. In addi\u00adtion to arti\u00adfi\u00adcial intel\u00adli\u00adgence for pat\u00adtern recog\u00adni\u00adtion, the experts at the Dres\u00adden-based com\u00adpa\u00adny pro\u00advide sup\u00adport. Depend\u00ading on the ser\u00advice lev\u00adel, they active\u00adly mon\u00adi\u00adtor cable health, eval\u00adu\u00adate anom\u00adalies, and pro\u00advide net\u00adwork oper\u00ada\u00adtors with con\u00adcrete rec\u00adom\u00admen\u00adda\u00adtions for action.<\/p>\n\n\n\n

The sys\u00adtem detects anom\u00adalies ear\u00adly on, pin\u00adpoints faults with pre\u00adci\u00adsion, and helps grid oper\u00ada\u00adtors main\u00adtain crit\u00adi\u00adcal infra\u00adstruc\u00adture with fore\u00adsight.<\/p>\n\n\n\n

Every mea\u00adsure\u00adment pro\u00advides data. And the more data there is, the bet\u00adter our under\u00adstand\u00ading of a cable becomes. HiMON\u00ae<\/sup> con\u00adsol\u00adi\u00addates these vast amounts of data and uses them to build a dig\u00adi\u00adtal twin. In the future, this vir\u00adtu\u00adal copy will show how the cable will per\u00adform under spe\u00adcif\u00adic con\u00addi\u00adtions. This trans\u00adforms sim\u00adple mon\u00adi\u00adtor\u00ading into true pre\u00addic\u00adtive main\u00adte\u00adnance \u2013 aging can be sim\u00adu\u00adlat\u00aded, risks assessed even ear\u00adli\u00ader, and mea\u00adsures planned well in advance. At the same time, insights from the sim\u00adu\u00adla\u00adtions can be applied to oth\u00ader cables. For net\u00adwork oper\u00ada\u00adtors, this shows, for exam\u00adple, which lines, under com\u00adpa\u00adra\u00adble con\u00addi\u00adtions, could next become crit\u00adi\u00adcal. In addi\u00adtion, cable man\u00adu\u00adfac\u00adtur\u00aders gain faster insights into where aging begins first, allow\u00ading them to specif\u00adi\u00adcal\u00adly address these weak points dur\u00ading devel\u00adop\u00adment and man\u00adu\u00adfac\u00adtur\u00ading. Thus, in the com\u00ading years, not only will the data\u00adbase grow, but so will the HiMON\u00ae<\/sup> uni\u00adverse itself.
