OFFSHORE CABLE TESTING <\/h3>\n

They are grow\u00ading in num\u00adber and get\u00adting big\u00adger and big\u00adger: Off\u00adshore wind parks make a sig\u00adnif\u00adi\u00adcant con\u00adtri\u00adbu\u00adtion to increas\u00ading the pro\u00adpor\u00adtion of envi\u00adron\u00admen\u00adtal\u00adly friend\u00adly elec\u00adtric\u00adi\u00adty in the ener\u00adgy mix. At the same time, the gen\u00ader\u00ada\u00adtive per\u00adfor\u00admance of wind tur\u00adbines is con\u00adstant\u00adly increas\u00ading. For new wind parks, for exam\u00adple, the oper\u00adat\u00ading volt\u00adage of the con\u00adnec\u00adtion cables from the wind tur\u00adbines to the col\u00adlec\u00adtion and con\u00adnect\u00ading plat\u00adforms is now being increased to 66 kV. <\/p>\n

The experts at the Inter\u00adna\u00adtion\u00adal Elec\u00adtrotech\u00adni\u00adcal Com\u00admis\u00adsion (IEC) there\u00adfore decid\u00aded to per\u00admit \u2014 in addi\u00adtion to the SOAK test (a 24-hour test at nom\u00adi\u00adnal volt\u00adage) \u2014 only res\u00ado\u00adnance test\u00ading for oper\u00adat\u00ading volt\u00adages greater than 36 kilo\u00advolts in the new stan\u00addard IEC 63026 for sub\u00adma\u00adrine cables up to 72.5 kV.<\/p>\n

HIGHVOLT is the only provider of a test\u00ading sys\u00adtem that is weath\u00ader-proof and there\u00adfore always avail\u00adable off\u00adshore despite adverse con\u00addi\u00adtions.<\/p>\n<\/div>\n<\/div>\n\n

MOBILE CABLE TESTING<\/h3>\n

HIGHVOLT is a pio\u00adneer when it comes to test\u00ading cables based on poly\u00admer insu\u00adlat\u00ading mate\u00adri\u00adals, such as cross-linked poly\u00adeth\u00adyl\u00adene (XLPE) in high-volt\u00adage appli\u00adca\u00adtions. The engi\u00adneers from Dres\u00adden built the first-ever mobile test\u00ading sys\u00adtem, which fits on a semi truck trail\u00ader. It can there\u00adfore be trans\u00adport\u00aded to almost any loca\u00adtion with\u00adout spe\u00adcial per\u00admits, even where there is no space for large test\u00ading sys\u00adtems. <\/p>\n

This includes cities and dense\u00adly pop\u00adu\u00adlat\u00aded regions where more and more cables are being rout\u00aded under\u00adground. The test\u00ading trail\u00ader is designed for cable lengths of up to 10 kilo\u00adme\u00adters; for longer cables, mul\u00adti\u00adple test\u00ading sys\u00adtems can also be con\u00adnect\u00aded in par\u00adal\u00adlel and in series.<\/p>\n<\/div>\n<\/div>\n

HEALTH CHECK 120 M ABOVE THE GROUND<\/h3>\n

Mechan\u00adi\u00adcal vibra\u00adtions of the rotors, light\u00adning strikes, fre\u00adquent load changes and a high num\u00adber of switch\u00ading oper\u00ada\u00adtions \u2014 the trans\u00adform\u00aders in the nacelles of wind tur\u00adbines are exposed to enor\u00admous loads. If they fail, it is a time-inten\u00adsive and cost\u00adly feat to repair or even replace them. <\/p>\n

What can be done? Ide\u00adal\u00adly, check the trans\u00adform\u00aders reg\u00adu\u00adlar\u00adly in order to iden\u00adti\u00adfy impend\u00ading dam\u00adage at an ear\u00adly stage. The stan\u00addard method for doing this is the induced volt\u00adage test with par\u00adtial dis\u00adcharge diag\u00adnos\u00adtics. But how does that work at more than a hun\u00addred meters above the ground, with lit\u00adtle space in the nacelle? HIGHVOLT has devel\u00adoped a portable test\u00ading sys\u00adtem that oper\u00ada\u00adtors or ser\u00advice providers can use to inspect the con\u00addi\u00adtion of the trans\u00adformer insu\u00adla\u00adtion direct\u00adly in the nacelle itself.<\/p>\n<\/div>\n<\/div>\n

XXL REACTORS FOR THE BACKBONE OF THE ENERGY TRANSITION<\/h3>\n

Renew\u00adable ener\u00adgy sources are often far away from pop\u00adu\u00adlat\u00aded areas. Ever larg\u00ader dis\u00adtances need to be trav\u00adeled to trans\u00adport the elec\u00adtric\u00adi\u00adty to where it is need\u00aded. Projects with sub\u00adma\u00adrine and land cables of sev\u00ader\u00adal hun\u00addred kilo\u00adme\u00adters are there\u00adfore increas\u00ading around the globe. Promi\u00adnent projects include the A\u2011Link, S\u00fcdlink and S\u00fcdostLink in Ger\u00admany, which form the back\u00adbone of the ener\u00adgy tran\u00adsi\u00adtion.<\/p>\n

The cable sec\u00adtions must be test\u00aded in advance so that noth\u00ading goes wrong when oper\u00adat\u00ading these cable sys\u00adtems. The num\u00adber one fail\u00adure source are the joints that con\u00adnect the cable sec\u00adtions to each oth\u00ader. Since con\u00adven\u00adtion\u00adal test\u00ading sys\u00adtems soon fall short in test\u00ading pow\u00ader, HIGHVOLT devel\u00adoped spe\u00adcial XXL reac\u00adtors. They pro\u00advide four times as much pow\u00ader at only twice the vol\u00adume of pre\u00advi\u00adous reac\u00adtors for the res\u00ado\u00adnance test\u00ading method. The pow\u00ader can be fur\u00adther increased through series and par\u00adal\u00adlel con\u00adnec\u00adtion, mean\u00ading that cable lengths of up to 200 kilo\u00adme\u00adters can be test\u00aded.<\/p>\n<\/div>\n<\/div>\n

OPERATION AT THE HEART OF THE ENERGY SUPPLY<\/h3>\n

Pow\u00ader trans\u00adform\u00aders are reach\u00ading a crit\u00adi\u00adcal age around the world, and at the same time, pow\u00ader grid loads are increas\u00ading due to bidi\u00adrec\u00adtion\u00adal load flows caused by the sup\u00adply of renew\u00adable ener\u00adgies. Oper\u00ada\u00adtors can check whether the equip\u00adment needs ser\u00advic\u00ading with tests such as the induced volt\u00adage test and loss mea\u00adsure\u00adments in a no-load state and under load. <\/p>\n

Often, this neces\u00adsi\u00adtates dis\u00adman\u00adtling the pow\u00ader trans\u00adformer, drain\u00ading the oil and then trans\u00adport\u00ading it to a repair site \u2014 at sig\u00adnif\u00adi\u00adcant logis\u00adti\u00adcal effort and expense. How\u00adev\u00ader, there\u2019s an eas\u00adi\u00ader way. <\/p>\n

HIGHVOLT has devel\u00adoped a test\u00ading sys\u00adtem for this pur\u00adpose that can be trans\u00adport\u00aded on a semi truck trail\u00ader, enabling this kind of high-volt\u00adage test\u00ading right in the pri\u00adma\u00adry sub\u00adsta\u00adtion. This way, the oper\u00ada\u00adtor can decide based on the mea\u00adsure\u00adments whether removal is even nec\u00ades\u00adsary, or if cheap\u00ader on-site repairs will suf\u00adfice.<\/p>\n<\/div>\n<\/div>\n

BIG BROTHER IN THE CABLE DUCT<\/h3>\n

When mal\u00adfunc\u00adtions occur dur\u00ading oper\u00ada\u00adtion, the HiRES Loca\u00adtor can help. This online mea\u00adsur\u00ading device is con\u00adnect\u00aded to medi\u00adum- and high-volt\u00adage cables dur\u00ading oper\u00ada\u00adtion and locates a break\u00addown in real time, imme\u00addi\u00adate\u00adly rais\u00ading an alarm. <\/p>\n

As a result, oper\u00ada\u00adtors know where they have to fix the prob\u00adlem. Con\u00adven\u00adtion\u00adal test\u00ading meth\u00adods, in con\u00adtrast, the fault is only locat\u00aded once the mal\u00adfunc\u00adtion has occurred. Then, after the event, a suit\u00adable, pow\u00ader\u00adful volt\u00adage source must be brought to the cable and mea\u00adsure\u00adments made in a cost\u00adly and time-inten\u00adsive pro\u00adce\u00addure. The HiRES Loca\u00adtor is there\u00adfore a cost-effec\u00adtive solu\u00adtion for mon\u00adi\u00adtor\u00ading cable sec\u00adtions in real time.<\/p>\n<\/div>\n<\/div>\n
