Unplanned outages of long underground cable routes result in a great deal of effort and high costs for network operators. How nice it would be to have a system that closely monitors the cable routes and provides recommendations for action to reduce these costs. HIGHVOLT has a solution for this that can also be retrofitted.<\/h3>\n

T<\/span>he ener\u00adgy tran\u00adsi\u00adtion can only suc\u00adceed with high\u00ader trans\u00admis\u00adsion capac\u00adi\u00adties. But com\u00admu\u00adni\u00adties and res\u00adi\u00addents often oppose the erec\u00adtion of high-volt\u00adage pylons in their neigh\u00adbor\u00adhoods, and peti\u00adtions, polit\u00adi\u00adcal con\u00adflicts and long law\u00adsuits are often the result. To avoid this has\u00adsle, net\u00adwork oper\u00ada\u00adtors like to use kilo\u00adme\u00adter-long under\u00adground cables, but then get them\u00adselves into oth\u00ader trou\u00adble because lay\u00ading, repair\u00ading and replac\u00ading these cables is many times more expen\u00adsive than with over\u00adhead lines. A mon\u00adi\u00adtor\u00ading sys\u00adtem for detect\u00ading cable faults and eval\u00adu\u00adat\u00ading par\u00adtial dis\u00adcharges would sig\u00adnif\u00adi\u00adcant\u00adly reduce the cost of repairs, cut pos\u00adsi\u00adble down\u00adtimes and allow net\u00adwork oper\u00ada\u00adtors to sleep more sound\u00adly again.<\/p>\n

160 km under control<\/h2>\n

For\u00adtu\u00adnate\u00adly, there is now such a mon\u00adi\u00adtor\u00ading system\u2014HiMON\u00ae from HIGHVOLT\u2014which uses two types of sen\u00adsors to record mea\u00adsured val\u00adues: the HiMAG\u00ae Red and HiMAG\u00ae Blue high-fre\u00adquen\u00adcy cur\u00adrent trans\u00adform\u00aders. Matthias Kap\u00adpler, HiMON\u00ae project man\u00adag\u00ader, explains: \u201cHiMAG\u00ae Red is respon\u00adsi\u00adble for detect\u00ading the trav\u00adel\u00ading waves\u2014also known as tran\u00adsients \u2014 caused by cable break\u00addowns in order to deter\u00admine the point of ori\u00adgin.\u201d For this pur\u00adpose, a HiMAG\u00ae Red sen\u00adsor with an asso\u00adci\u00adat\u00aded HiRES\u00ae Loca\u00adtor event recorder is placed at the begin\u00adning and end of each cable sec\u00adtion. HiMAG\u00ae Blue, on the oth\u00ader hand, is installed along the cable route at the ground\u00ading sleeves at dis\u00adtances of up to twelve kilo\u00adme\u00adters. \u201cThe HiMAG\u00ae Blue sen\u00adsors detect micro\u00adscop\u00adic puls\u00ades that occur at pos\u00adsi\u00adble fault loca\u00adtions in the cable insu\u00adla\u00adtion,\u201d adds Dan Keller, Util\u00adi\u00adty Busi\u00adness Sales Man\u00adag\u00ader at HIGHVOLT.<\/p>\n

\u201cThe sys\u00adtem can record very pre\u00adcise\u00adly where and in what inten\u00adsi\u00adty par\u00adtial dis\u00adcharges occur. From this, clear rec\u00adom\u00admen\u00adda\u00adtions for action can be derived.\u201d Dan Keller, Sales Man\u00adag\u00ader Util\u00adi\u00adty Busi\u00adness at HIGHVOLT<\/cite><\/p>\n<\/blockquote>\n

Detect\u00ading par\u00adtial dis\u00adcharges in long under\u00adground cable runs is very cost\u00adly using tra\u00addi\u00adtion\u00adal means. \u201cThe dis\u00adad\u00advan\u00adtage of sys\u00adtems based on the tra\u00addi\u00adtion\u00adal\u00adly pre\u00advail\u00ading par\u00adtial dis\u00adcharge (PD) mea\u00adsure\u00adment method\u00adol\u00ado\u00adgy is that they require a sen\u00adsor at each joint,\u201d says Keller. In the past, the high asso\u00adci\u00adat\u00aded instal\u00adla\u00adtion costs often led cable oper\u00ada\u00adtors to choose to use only acoustic-sig\u00adnal-sens\u00ading or tem\u00adper\u00ada\u00adture-sens\u00ading sys\u00adtems using fiber optic cables. How\u00adev\u00ader, this leaves cer\u00adtain dam\u00adage to the cable insu\u00adla\u00adtion unde\u00adtect\u00aded.<\/p>\n

HiMON\u00ae opti\u00admal\u00adly sup\u00adple\u00adments the fiber-optic-based sys\u00adtems already in use with a sys\u00adtem for detect\u00ading elec\u00adtri\u00adcal par\u00adtial dis\u00adcharge sig\u00adnals. The TruePD method\u00adol\u00ado\u00adgy devel\u00adoped for this pur\u00adpose sig\u00adnif\u00adi\u00adcant\u00adly reduces instal\u00adla\u00adtion efforts because the mea\u00adsur\u00ading points are only installed at the ground\u00ading sleeves at dis\u00adtances of up to twelve kilo\u00adme\u00adters. HiMON\u00ae thus saves a lot of mate\u00adr\u00adi\u00adal and mon\u00adey. In addi\u00adtion, for the first time, HiMON\u00ae also allows the cable sec\u00adtions between the mea\u00adsur\u00ading points to be mon\u00adi\u00adtored with cen\u00adtime\u00adter-exact accu\u00adra\u00adcy. Alter\u00adna\u00adtive PD measur\u00ading sys\u00adtems can usu\u00adal\u00adly only mon\u00adi\u00adtor the joints.<\/p>\n

Easy to install<\/h2>\n

The HiMON\u00ae mon\u00adi\u00adtor\u00ading sys\u00adtem is also eas\u00adi\u00ader to install and retro\u00adfit due to the low num\u00adber of mea\u00adsur\u00ading points and the new\u00adly devel\u00adoped design. Matthias Kap\u00adpler explains, \u201cUnlike con\u00adven\u00adtion\u00adal sys\u00adtems, the HiMAG\u00ae sen\u00adsors can also be retro\u00adfit\u00adted to already installed cable sys\u00adtems thanks to their sep\u00ada\u00adra\u00adble core design.\u201d<\/p>\n

Action recommendations<\/h2>\n

Part of the ener\u00adgy tran\u00adsi\u00adtion is also the dig\u00adi\u00adti\u00adza\u00adtion of exist\u00ading infra\u00adstruc\u00adtures to improve con\u00addi\u00adtion monitor\u00ading and main\u00adte\u00adnance. The mea\u00adsure\u00adment sig\u00adnals cap\u00adtured by the HiMON\u00ae sen\u00adsors are dig\u00adi\u00adtized by the asso\u00adci\u00adat\u00aded HiRES\u00ae TruePD event recorder and this data is then sent to a spe\u00adcial\u00adly secured cloud where it is ana\u00adlyzed by intel\u00adli\u00adgent algo\u00adrithms. \u201cThe cable net\u00adwork oper\u00ada\u00adtor then receives infor\u00adma\u00adtion about the con\u00addi\u00adtion of the cable route includ\u00ading visu\u00adal infor\u00adma\u00adtion in the form of traf\u00adfic lights,\u201d says Kap\u00adpler. If the traf\u00adfic light turns red, HiMON\u00ae shows fur\u00adther details about the prob\u00adlem such as which cable com\u00adpo\u00adnent is affect\u00aded, or the inten\u00adsi\u00adty of the par\u00adtial dis\u00adcharges. \u201cThe sys\u00adtem can record very pre\u00adcise\u00adly where and in what inten\u00adsi\u00adty par\u00adtial dis\u00adcharges occur, from which clear rec\u00adom\u00admen\u00adda\u00adtions for action can be derived,\u201d Keller explains. This is impor\u00adtant infor\u00adma\u00adtion for cable net\u00adwork oper\u00ada\u00adtors in order to repair pos\u00adsi\u00adble defects dur\u00ading planned cable main\u00adte\u00adnance. This is easy on the wal\u00adlet and ensures secure net\u00adworks.<\/p>\n
