C<\/span>onsid\u00ader this sce\u00adnario: Short\u00adly before the win\u00adter sea\u00adson, an unknown prob\u00adlem aris\u00ades at an off\u00adshore wind farm. With so lit\u00adtle time before the end of the test\u00ading season\u2014and in this wea\u00adther\u2014no one is able to vis\u00adit the site to car\u00adry out a high-volt\u00adage test. So the win\u00adter storms rage for months and the rotors are in per\u00adma\u00adnent motion\u2014but it all goes to waste.
\n
\nThe elec\u00adtri\u00adcal pow\u00ader that is gen\u00ader\u00adat\u00aded can\u00adnot be used on land. The bad weath\u00ader and low tem\u00adper\u00ada\u00adtures mean that no work can be car\u00adried out on site, so the engi\u00adneers have to wait until at least April before they can vis\u00adit the wind farm and find out what the prob\u00adlem is. In the mean\u00adtime, the wind farm oper\u00ada\u00adtor keeps star\u00ading at the cal\u00aden\u00addar: For every day that they are unable to sup\u00adply pow\u00ader to the grid, they lose more and more mon\u00adey. When will it final\u00adly be sum\u00admer again?<\/p>\n

So what is need\u00aded are prac\u00adti\u00adcal, weath\u00ader-proof off\u00adshore test\u00ading sys\u00adtems.<\/p><\/blockquote>\n

Con\u00adven\u00adtion\u00adal test\u00ading sys\u00adtems for inspect\u00ading cables are not designed for the con\u00addi\u00adtions at an off\u00adshore plat\u00adform. When exposed to the salt in the air, as well as rain, snow, and rough seas, they can\u00adnot oper\u00adate reli\u00adably. Solu\u00adtions that have proved use\u00adful for on-site test\u00ading on land\u2014the use of tents, for example\u2014are not going to be much help here. Fur\u00adther\u00admore, trans\u00adport\u00ading mate\u00adri\u00adals and peo\u00adple with spe\u00adcial ships or heli\u00adcopters is dif\u00adfi\u00adcult and has to be planned well in advance. The win\u00addow of oppor\u00adtu\u00adni\u00adty where the wind farms are actu\u00adal\u00adly acces\u00adsi\u00adble amounts to only a few months of the year. So what is need\u00aded are prac\u00adti\u00adcal, weath\u00ader-proof off\u00adshore test\u00ading sys\u00adtems.<\/p>\n

Resonance testing<\/h3>\n

In response to these two factors\u2014the weath\u00ader at sea and the IEC standardization\u2014HIGHVOLT has devel\u00adoped an off\u00adshore test\u00ading sys\u00adtem which ful\u00adfills the require\u00adments for on-site test\u00ading on the high seas. The tech\u00adnol\u00ado\u00adgy is based on the tried-and-test\u00aded HIGHVOLT res\u00ado\u00adnance test\u00ading sys\u00adtems, which have long been in use in hun\u00addreds of appli\u00adca\u00adtions all over the world.<\/p>\n

RESONANCE TESTING<\/h5>\n

The res\u00ado\u00adnance test\u00ading method repro\u00adduces the load on a cable in nor\u00admal oper\u00ada\u00adtion at nom\u00adi\u00adnal volt\u00adage and at approx\u00adi\u00admate\u00adly grid fre\u00adquen\u00adcy. A res\u00ado\u00adnant cir\u00adcuit com\u00adpris\u00ading a test induc\u00adtor (induc\u00adtance) and test cable (capac\u00adi\u00adtance) is estab\u00adlished for this pur\u00adpose. The vari\u00adable fre\u00adquen\u00adcy (10\u2013500 Hz) of the test sys\u00adtem sup\u00adply is auto\u00admat\u00adi\u00adcal\u00adly set to the res\u00ado\u00adnance fre\u00adquen\u00adcy of the test cir\u00adcuit, which min\u00adi\u00admizes the required feed-in pow\u00ader.<\/p>\n

<\/p>\n

Over half of all prob\u00adlems are due to instal\u00adla\u00adtion errors. These can be reli\u00adably detect\u00aded by means of res\u00ado\u00adnance test\u00ading.<\/p>\n<\/div>\n<\/div>\n

The nec\u00ades\u00adsary adap\u00adta\u00adtions have been made with out\u00adstand\u00ading atten\u00adtion to detail: The engi\u00adneers in Dres\u00adden checked the suit\u00adabil\u00adi\u00adty of every sin\u00adgle com\u00adpo\u00adnent for off\u00adshore use and upgrad\u00aded or redesigned them as nec\u00ades\u00adsary. Exam\u00adples include the use of cor\u00adro\u00adsion-free mate\u00adri\u00adals which are extreme\u00adly resis\u00adtant to salt water spray, shield\u00aded and off\u00adshore-cer\u00adti\u00adfied plug con\u00adnec\u00adtors, and a gas-insu\u00adlat\u00aded mod\u00adule for reli\u00adable, fault-free con\u00adnec\u00adtion of the sys\u00adtem com\u00adpo\u00adnents and volt\u00adage mea\u00adsure\u00adment.<\/p>\n

With this test\u00ading sys\u00adtem, HIGHVOLT pro\u00advides wind farm oper\u00ada\u00adtors, cable man\u00adu\u00adfac\u00adtur\u00aders, and test\u00ading ser\u00advice providers with the flex\u00adi\u00adbil\u00adi\u00adty they need to safe\u00adguard the func\u00adtion\u00ading of com\u00adplex off\u00adshore elec\u00adtri\u00adcal infra\u00adstruc\u00adtures on a contin\u00aduous basis.<\/p>\n

The engi\u00adneers in Dres\u00adden checked the suit\u00adabil\u00adi\u00adty of every sin\u00adgle com\u00adpo\u00adnent for off\u00adshore use.<\/p><\/blockquote>\n

And if some\u00adthing should go wrong short\u00adly before the end of the next test\u00ading sea\u00adson, this solu\u00adtion will enable them to test the sys\u00adtems quick\u00adly, rec\u00adti\u00adfy the prob\u00adlem and har\u00adness the pow\u00ader of the win\u00adter winds to the fullest pos\u00adsi\u00adble extent.<\/p>\n
