How\u00adev\u00ader, a new trans\u00adformer was out of the ques\u00adtion for Elia. After all, all oth\u00ader com\u00adpo\u00adnents were still func\u00adtion\u00ading with\u00adout prob\u00adlems.

Before replac\u00ading the tap chang\u00ader, the ser\u00advice provider Main\u00adte\u00adnance Part\u00adners pre\u00adpared the trans\u00adformer for two days.

First, the old tap chang\u00ader need\u00aded to be removed. To do so, we cut open the cov\u00ader using a blow torch and lift\u00aded the tap chang\u00ader out of the trans\u00adformer tank by crane.<\/span><\/p>\nWe were then able to bring in the oil com\u00adpart\u00adment of the new tap chang\u00ader, along with the divert\u00ader switch insert, and posi\u00adtion the selec\u00adtor. Then we con\u00adnect\u00aded the selec\u00adtor in the trans\u00adformer with the tap wind\u00ading and to the old sup\u00adply lines via indi\u00advid\u00adu\u00adal\u00adly adjust\u00aded cables. Final\u00adly, the motor-dri\u00adve unit and the link\u00adage from the tap chang\u00ader to the dri\u00adve were attached.<\/span><\/p>\n Reinhausen\u2019s ser\u00advice range includes much more than replac\u00ading on-load tap-chang\u00aders.

Test\u00ading was done in the next step. For this pur\u00adpose, experts from Main\u00adte\u00adnance Part\u00adners mea\u00adsured the trans\u00admis\u00adsion ratio at low volt\u00adage to see whether the tap chang\u00ader stepped down the volt\u00adage prop\u00ader\u00adly. In this way we were able to ensure that all sup\u00adply lines were attached to the cor\u00adrect points on the selec\u00adtor.

This con\u00adclud\u00aded the work onsite. Main\u00adte\u00adnance Part\u00adners closed the trans\u00adformer tank again and filled it with oil.
