Bushing monitoring<\/h2>\n

B<\/span>ush\u00adings are among the most sen\u00adsi\u00adtive com\u00adpo\u00adnents in trans\u00adform\u00aders. Not only do they have to with\u00adstand sev\u00ader\u00adal hun\u00addred thou\u00adsand volts, they must also be able to sup\u00adport high ther\u00admal and mechan\u00adi\u00adcal loads. That\u2019s why around 17% of major trans\u00adformer fail\u00adures are attrib\u00aduted to defec\u00adtive bush\u00adings. Like\u00adwise, such defects are also the main cause of trans\u00adformer fires and explo\u00adsions. Nev\u00ader\u00adthe\u00adless, these can be avoid\u00aded with an ear\u00adly warn\u00ading sys\u00adtem and time\u00adly replace\u00adment. For this pur\u00adpose, Rein\u00adhausen has devel\u00adoped the MSENSE\u00ae BM online mon\u00adi\u00adtor\u00ading sys\u00adtem, with which the con\u00addi\u00adtion of bush\u00adings can be con\u00adtin\u00adu\u00adous\u00adly mon\u00adi\u00adtored. If the sys\u00adtem detects a fault, an alarm is trig\u00adgered, allow\u00ading the oper\u00ada\u00adtor to inter\u00advene before a fail\u00adure occurs.
\n<\/p>\n

To do this, the new mon\u00adi\u00adtor\u00ading sys\u00adtem uses two key met\u00adrics \u2013 capac\u00adi\u00adty and dis\u00adsi\u00adpa\u00adtion fac\u00adtor \u2013 which pro\u00advide infor\u00adma\u00adtion on the con\u00addi\u00adtion of the insu\u00adla\u00adtion. A devi\u00ada\u00adtion of the bush\u00ading val\u00adues in one phase (C1 or tan \u03b4 ) from the orig\u00adi\u00adnal val\u00adues indi\u00adcates that the con\u00addi\u00adtion of the insu\u00adla\u00adtion has changed and the user is noti\u00adfied using a two-stage lim\u00adit-val\u00adue sys\u00adtem (warn\u00ading and alarm).The process for ana\u00adlyz\u00ading the mea\u00adsure\u00adment data is com\u00adplex. An algo\u00adrithm devel\u00adoped by Rein\u00adhausen known as the dou\u00adble-ref\u00ader\u00adence method (2\/3 ref\u00ader\u00adence method) elim\u00adi\u00adnates the reliance on net\u00adwork imbal\u00adances and tem\u00adper\u00ada\u00adture fluc\u00adtu\u00ada\u00adtions and there\u00adfore enables reli\u00adable and unam\u00adbigu\u00adous con\u00addi\u00adtion assess\u00adment. Trans\u00adform\u00aders that are already in oper\u00ada\u00adtion can also be retro\u00adfit\u00adted with the MSENSE\u00ae BM online mon\u00adi\u00adtor\u00ading sys\u00adtem.<\/p>\n

HiRES Locator<\/h2>\n

W<\/span>here is the fault? Search\u00ading for break\u00addowns in miles of medi\u00adum-volt\u00adage and high-volt\u00adage cabling is a lit\u00adtle bit like look\u00ading for a nee\u00addle in a haystack. Pre\u00advi\u00adous\u00adly, a fault could only be pin\u00adpoint\u00aded offline after a mal\u00adfunc\u00adtion had occurred. The mea\u00adsure\u00adment need\u00aded would then be com\u00adplex and time-con\u00adsum\u00ading, and often addi\u00adtion\u00adal inves\u00adti\u00adga\u00adtion was need\u00aded before the fault could be local\u00adized. How\u00adev\u00ader, the experts at HIGHVOLT have now devel\u00adoped a new mea\u00adsur\u00ading device called the HiRES Loca\u00adtor, which makes fault local\u00adiza\u00adtion quick, easy, and cost-effec\u00adtive. This is good news not only for grid oper\u00ada\u00adtors and ener\u00adgy providers, who are required to mon\u00adi\u00adtor cabling sys\u00adtems of ever greater com\u00adplex\u00adi\u00adty, but also for cable man\u00adu\u00adfac\u00adtur\u00aders, who can inte\u00adgrate the HiRES Loca\u00adtor into their test\u00ading pro\u00adce\u00addures for the pur\u00adpos\u00ades of qual\u00adi\u00adty assur\u00adance.<\/p>\n

The HiRES Loca\u00adtor works in the fol\u00adlow\u00ading way: A dig\u00adi\u00adtal recorder is con\u00adnect\u00aded to the cable dur\u00ading active oper\u00ada\u00adtion and local\u00adizes a breakdown imme\u00addi\u00adate\u00adly while it\u2019s occur\u00adring, so the fault is local\u00adized with the sys\u00adtem still online, not after the fact. The mea\u00adsure\u00adment is based on the impulse reflec\u00adtion method, also known as TDR (time-domain reflec\u00adtom\u00ade\u00adtry). Pre\u00advi\u00adous\u00adly, mea\u00adsure\u00adment tech\u00adni\u00adcians using this method would gen\u00ader\u00adate an arti\u00adfi\u00adcial break \u2011down sig\u00adnal \u2013 an elec\u00adtri\u00adcal impulse which would prop\u00ada\u00adgate through the con\u00adduc\u00adtor in wave form. If the wave encoun\u00adters a mate\u00adr\u00adi\u00adal fault, it is reflect\u00aded back. The loca\u00adtion of the break\u00addown is then cal\u00adcu\u00adlat\u00aded from the time dif\u00adfer\u00adence between the sent and received sig\u00adnal. The HiRES Loca\u00adtor can now deter\u00admine this live and in real time.<\/p>\n
