What damages the transformer<\/big><\/h2>\n\n\n\n

The ser\u00advice life of a trans\u00adformer is cru\u00adcial\u00adly depen\u00addent on the transformer\u2019s oper\u00adat\u00ading con\u00addi\u00adtions and its envi\u00adron\u00adment.

3 %<\/span> points in the mois\u00adture in the insu\u00adla\u00adtion make a big dif\u00adfer\u00adence.

17 %<\/span> of trans\u00adformer fail\u00adures can be traced back to defec\u00adtive bush\u00adings.<\/p>\n

For strate\u00adgi\u00adcal\u00adly impor\u00adtant and crit\u00adi\u00adcal trans\u00adform\u00aders, a com\u00adpre\u00adhen\u00adsive dis\u00adsolved gas analy\u00adsis (DGA) of the insu\u00adlat\u00ading oil is vital for the con\u00addi\u00adtion assess\u00adment, fault qual\u00adi\u00adfi\u00adca\u00adtion and oper\u00ada\u00adtional reli\u00ada\u00adbil\u00adi\u00adty.

An excess con\u00adcen\u00adtra\u00adtion of hydro\u00adgen, car\u00adbon monox\u00adide and mois\u00adture in the oil is a pri\u00adma\u00adry indi\u00adca\u00adtor of pos\u00adsi\u00adble dam\u00adage in the wind\u00adings with ther\u00admal and elec\u00adtri\u00adcal caus\u00ades.

What should be done with the treasure trove of data?<\/big><\/h2>\n\n\n\n

The MSENSE\u00ae real\u00adizes its full poten\u00adtial when com\u00adbined with ETOS\u00ae, the first open oper\u00adat\u00ading sys\u00adtem for pow\u00ader trans\u00adform\u00aders. This intel\u00adli\u00adgent sys\u00adtem helps to opti\u00admize and pro\u00adtect the entire ser\u00advice life of the trans\u00adformer, which ben\u00ade\u00adfits all par\u00adties: man\u00adu\u00adfac\u00adtur\u00aders, EPCs and grid oper\u00ada\u00adtors.<\/p>\n\n\n\n

<\/figure>\n\n\n\n

1<\/span> DESIGN AND PRODUCTION<\/h3>\n\n\n\n

The life of a trans\u00adformer begins with its design and pro\u00adduc\u00adtion. ETOS \u00ae pro\u00advides man\u00adu\u00adfac\u00adtur\u00aders with a pre\u00adcon\u00adfig\u00adured and test\u00aded sys\u00adtem that is ready for con\u00adnec\u00adtion and will cut costs by 65 % when com\u00adpared with con\u00adven\u00adtion\u00adal automa\u00adtion. New dig\u00adi\u00adtal busi\u00adness mod\u00adels, such as live sup\u00adport, are also pos\u00adsi\u00adble. In addi\u00adtion, the data col\u00adlect\u00aded and expe\u00adri\u00adence gained in the field can be used to opti\u00admize future trans\u00adformer designs.<\/p>\n\n\n\n

2<\/span> DELIVERY AND INSTALLATION<\/h3>\n\n\n\n

After the trans\u00adformer has been pro\u00adduced, it is sent to its des\u00adti\u00adna\u00adtion. EPCs (Engi\u00adneer\u00ading-Pro\u00adcure\u00adment-Con\u00adstruc\u00adtion com\u00adpa\u00adnies) per\u00adform the instal\u00adla\u00adtion, dur\u00ading which up to 70 % on costs can be saved with the ETOS \u00ae solu\u00adtion. This is because, instead of each sen\u00adsor hav\u00ading many cop\u00adper cables, just a sin\u00adgle fiber-glass cable is used for con\u00adnec\u00adtion to the mon\u00adi\u00adtor\u00ading sys\u00adtem. The intel\u00adli\u00adgence is locat\u00aded direct\u00adly in the con\u00adtrol cab\u00adi\u00adnet on the trans\u00adformer. In addi\u00adtion, data inte\u00adgra\u00adtion into a SCADA sys\u00adtem is much sim\u00adpler thanks to a stan\u00addard\u00adized com\u00admu\u00adni\u00adca\u00adtion pro\u00adto\u00adcol (e.g. IEC 61850).<\/p>\n\n\n\n

3<\/span>OPERATION<\/h3>\n\n\n\n

After a trans\u00adformer has been installed, it can be oper\u00adat\u00aded for decades. Net\u00adwork\u00ading makes it sub\u00adstan\u00adtial\u00adly eas\u00adi\u00ader to uti\u00adlize the capac\u00adi\u00adty and ser\u00advice life of the trans\u00adformer. In this way, load and weath\u00ader fore\u00adcasts are trans\u00admit\u00adted via the con\u00adtrol room direct\u00adly to the trans\u00adformer. This enables the trans\u00adformer to auto\u00admat\u00adi\u00adcal\u00adly make deci\u00adsions, such as when the cool\u00ading should be acti\u00advat\u00aded.<\/p>\n\n\n\n

4<\/span>CONDITION ASSESSMENT AND MAINTENANCE<\/h3>\n\n\n\n

Dur\u00ading oper\u00ada\u00adtion, asset-man\u00adage\u00adment and ser\u00advice per\u00adson\u00adnel are respon\u00adsi\u00adble for per\u00adform\u00ading main\u00adte\u00adnance, over\u00adhaul and mod\u00adern\u00adiza\u00adtion tasks on the trans\u00adformer. They can use the data col\u00adlect\u00aded from the trans\u00adformer to con\u00adtin\u00adu\u00adous\u00adly mon\u00adi\u00adtor its con\u00addi\u00adtion and min\u00adi\u00admize fail\u00adures. Cal\u00adcu\u00adla\u00adtions have demon\u00adstrat\u00aded that online mon\u00adi\u00adtor\u00ading reduces the fail\u00adure rate by 42 %.<\/p>\n\n\n\n

5<\/span> STRATEGIC PLANNING<\/h3>\n\n\n\n

When should I invest in new equip\u00adment? Where should this equip\u00adment be used, and how should it be con\u00adfig\u00adured? Grid plan\u00adners can use the data gained from the trans\u00adformer for future load fore\u00adcasts, and reduce the ser\u00advice-life costs of the trans\u00adformer as a result. In addi\u00adtion, more pre\u00adcise require\u00adment spec\u00adi\u00adfi\u00adca\u00adtions can be sent to man\u00adu\u00adfac\u00adtur\u00aders for future invest\u00adments.<\/p>\n\n\n\n
