A<\/span>trans\u00adformer breathes out and in again a cou\u00adple of times a year, depend\u00ading on uti\u00adliza\u00adtion. This is because an increase in load caus\u00ades the insulat\u00ading medi\u00adum in the trans\u00adformer to heat up and expand, push\u00ading the air in the expan\u00adsion tank out into the atmos\u00adphere. When the oil cools down again, it con\u00adtracts and draws in the out\u00adside air.<\/p>\n

Dehy\u00addrat\u00ading breathers are used to make sure that no mois\u00adture gets into the insu\u00adlat\u00ading medi\u00adum when the trans\u00adformer breathes in. Each trans\u00adformer most\u00adly has a min\u00adi\u00admum of two breathers: one for the oil cir\u00adcuit in the tap chang\u00ader, the big\u00adger ones for the trans\u00adformer tank. The sub\u00adstance that elim\u00adi\u00adnates the mois\u00adture is called sil\u00adi\u00adca gel. Thanks to its water-absorb\u00ading prop\u00ader\u00adties, it is also used as a des\u00adic\u00adcant in oth\u00ader applications\u2014inside the pack\u00adag\u00ading of mois\u00adture-sen\u00adsi\u00adtive elec\u00adtron\u00adics, for exam\u00adple.
\n
\nAs its abil\u00adi\u00adty to absorb water is lim\u00adit\u00aded, the sil\u00adi\u00adca gel in con\u00adven\u00adtion\u00adal dehy\u00addrat\u00ading breathers has to be replaced and dis\u00adposed of reg\u00adularly\u2014around two to three times a year on aver\u00adage. This fre\u00adquen\u00adcy increas\u00ades fur\u00adther as more renew\u00adable pow\u00ader is fed into the grid, as this means the trans\u00adformer has to work under high load con\u00addi\u00adtions more often. For grid oper\u00ada\u00adtors, this is a task that takes up valu\u00adable time and ties up resources, and the result\u00ading costs are not to be under\u00ades\u00adti\u00admat\u00aded.<\/p>\n

The main\u00adte\u00adnance-free dehy\u00addrat\u00ading breathers make life much eas\u00adi\u00ader for Karl-Heinz Jenal, oper\u00ada\u00adtional super\u00advi\u00adsor at VSE Verteil\u00adnetz GmbH. (\u00a9 Alexan\u00adder Neu)<\/figcaption><\/figure>\n

Karl-Heinz Jenal, who works as an oper\u00ada\u00adtional super\u00advi\u00adsor at Saar\u00adland-based ener\u00adgy sup\u00adpli\u00ader VSE Verteil\u00adnetz GmbH and is respon\u00adsi\u00adble for main\u00adtain\u00ading the equip\u00adment, explains: \u201cWe have 56 high-volt\u00adage instal\u00adla\u00adtions in our grid, each of which con\u00adtains two trans\u00adform\u00aders. Some\u00adone has to go out to each one on a reg\u00adu\u00adlar basis to check whether the des\u00adic\u00adcant is still work\u00ading prop\u00ader\u00adly. Over the course of a year, the time spent on main\u00adte\u00adnance real\u00adly adds up. And then you have to fac\u00adtor in the met\u00adric ton of sil\u00adi\u00adca gel that we have to dis\u00adpose of and replace.\u201d At least, that\u2019s how things used to be.<\/p>\n

For VSE Verteil\u00adnetz GmbH, these tasks and the asso\u00adci\u00adat\u00aded costs will soon be a thing of the past, as all of its trans\u00adform\u00aders have been fit\u00adted with the main\u00adte\u00adnance-free MTRAB\u00ae dehy\u00addrat\u00ading breather from Rein\u00adhausen sub\u00adsidiary MESSKO. The breather still uses sil\u00adi\u00adca gel, but unlike the pre\u00advi\u00adous tech\u00adnol\u00ado\u00adgy, the MTRAB\u00ae is able to regen\u00ader\u00adate itself. Sen\u00adsors mea\u00adsure the mois\u00adture in the des\u00adic\u00adcant. An algo\u00adrithm stored in the con\u00adtrol sys\u00adtem eval\u00adu\u00adates these mea\u00adsure\u00adments and an elec\u00adtric heat\u00ading sys\u00adtem is acti\u00advat\u00aded auto\u00admat\u00adi\u00adcal\u00adly when the sat\u00adu\u00adra\u00adtion point is reached. After around two and a half hours, the sil\u00adi\u00adca gel is dry again.<\/p>\n

A Cost-Effective Solution<\/h2>\n

VSE Verteil\u00adnetz GmbH first used the MTRAB\u00ae in 2008, when it was adding a new trans\u00adformer to the fleet. Jens Leinen\u00adbach, head of grid oper\u00ada\u00adtions, recalls: \u201cWe were try\u00ading to work out how we could cut down on main\u00adte\u00adnance in the long term. That\u2019s why we were keen to try out a new prod\u00aduct and see whether it proved its worth in prac\u00adtice.\u201d And the MTRAB\u00ae def\u00adi\u00adnite\u00adly passed the test. Eight years lat\u00ader, VSE Verteil\u00adnetz GmbH ordered MESSKO dehy\u00addrat\u00ading breathers for anoth\u00ader 35 trans\u00adform\u00aders and in 2019, the com\u00adpa\u00adny decid\u00aded to con\u00advert the entire fleet.<\/p>\n

\u201cWe want\u00aded to bring all of our equip\u00adment up to the same lev\u00adel. We delib\u00ader\u00adate\u00adly opt\u00aded for a qual\u00adi\u00adty product\u2014something that is not offered by many man\u00adu\u00adfac\u00adtur\u00aders on the mar\u00adket. The fact that we have been work\u00ading with MESSKO and Rein\u00adhausen for many years also played a key role in the deci\u00adsion. Hav\u00ading a part\u00adner that we know and trust is impor\u00adtant to us,\u201d explains Leinen\u00adbach.<\/p>\n

As an addi\u00adtion\u00adal advan\u00adtage, the MTRAB\u00ae dehy\u00addrat\u00ading breathers can be net\u00adworked so that error mes\u00adsages are sent straight to the con\u00adtrol room. And even if the elec\u00adtron\u00adics sys\u00adtem fails at some point, the MTRAB\u00ae still func\u00adtions as a con\u00adven\u00adtion\u00adal dehy\u00addrat\u00ading breather. The com\u00adpa\u00adny has yet to see a sin\u00adgle error mes\u00adsage: \u201cOur expe\u00adri\u00adence has been entire\u00adly pos\u00adi\u00adtive so far. We haven\u2019t had to wor\u00adry about a thing since the equip\u00adment was installed,\u201d says Leinen\u00adbach<\/p>\n

Simple Installation<\/h2>\n

Jenal, who over\u00adsaw the con\u00adver\u00adsion work, agrees. \u201cThe instal\u00adla\u00adtion process is self-explana\u00adto\u00adry and very straight\u00adforward. Our own staff were able to car\u00adry out the work when they were going to a pri\u00adma\u00adry sub\u00adsta\u00adtion any\u00adway for oth\u00ader rea\u00adsons.\u201d The new equip\u00adment has freed up resources that the oper\u00ada\u00adtional super\u00advi\u00adsor and his team can now allo\u00adcate else\u00adwhere. When you work for an ener\u00adgy sup\u00adpli\u00ader, there are always plen\u00adty of oth\u00ader things to be get\u00adting on with.<\/p>\n

\u201cFrom a medi\u00adum and long term per\u00adspec\u00adtive, VSE has made the right deci\u00adsion to save costs and, in doing so, joins the ranks of over 1,000 sat\u00adis\u00adfied cus\u00adtomers world\u00adwide who have been suc\u00adcess\u00adful\u00adly using our MTRAB\u00ae dehy\u00addrat\u00ading breathers for many years,\u201d explains Wern\u00ader Sam\u00admet, Messko\/MR Area Sales Man\u00adag\u00ader for Europe.<\/p>\n

The MESSKO\u00ae MTRAB\u00ae <\/a>has proven itself many times over in the field since it was first launched over 15 years ago \u2014 there are now about 80,000 of these breathers installed world\u00adwide. The main\u00adte\u00adnance-free dehy\u00addrat\u00ading breather min\u00adi\u00admizes the ingress of mois\u00adture into the insu\u00adlat\u00ading flu\u00adid of trans\u00adform\u00aders, tap chang\u00aders, and oth\u00ader elec\u00adtri\u00adcal equip\u00adment filled with insu\u00adlat\u00ading flu\u00adids. The MESSKO\u00ae MTRAB\u00ae can regen\u00ader\u00adate the sil\u00adi\u00adca gel itself thanks to the use of tem\u00adper\u00ada\u00adture and mois\u00adture sen\u00adsors com\u00adbined with intel\u00adli\u00adgent algo\u00adrithms \u2014 sav\u00ading inspec\u00adtion and main\u00adte\u00adnance costs.<\/p>\n<\/div>\n<\/div>\n
