To Determine the Residual Lifetime of Electrical Joints and Contacts using Infrared Measurement<\/span><\/h1>\n

Elec\u00adtri\u00adcal equip\u00adment is age\u00ading \u2014 the pro\u00adduced pow\u00ader dis\u00adsi\u00adpa\u00adtion is con\u00adstant\u00adly increas\u00ading. Nev\u00ader\u00adthe\u00adless, elec\u00adtric switchgears should be oper\u00adat\u00aded as inten\u00adsive\u00adly and as long as pos\u00adsi\u00adble, since they are extreme\u00adly expensive.<\/p>\n

As a con\u00adse\u00adquence, such instal\u00adla\u00adtions have to be inspect\u00aded reg\u00adu\u00adlar\u00adly. In order to ensure an unin\u00adter\u00adrupt\u00aded pow\u00ader sup\u00adply dur\u00ading diag\u00adno\u00adsis, infrared cam\u00aderas are used. These allow to mea\u00adsure the tem\u00adper\u00ada\u00adtures with\u00adout direct con\u00adtact. The actu\u00adal prob\u00adlem, how\u00adev\u00ader, is not the mea\u00adsure\u00adment of the tem\u00adper\u00ada\u00adtures itself, but the eval\u00adu\u00ada\u00adtion of the mea\u00adsured val\u00adues. All pre\u00advi\u00adous meth\u00adods exclu\u00adsive\u00adly eval\u00adu\u00adate the tem\u00adper\u00ada\u00adture of junc\u00adtion with\u00adout con\u00adsid\u00ader\u00ading the influ\u00adences of envi\u00adron\u00admen\u00adtal and load con\u00addi\u00adtions.  For this rea\u00adson it is impos\u00adsi\u00adble to make a reli\u00adable state\u00adment about the con\u00addi\u00adtion of the joints and contacts.<\/p>\n\n\n\n

There\u00adfore, THETA<\/span>, the Insti\u00adtute of High\u00advolt\u00adage and High\u00adcur\u00adrent at Dres\u00adden Uni\u00adver\u00adsi\u00adty of Tech\u00adnol\u00ado\u00adgy, RIBE<\/span> GmbH &<\/span> Co.

There has been held an Euro\u00adpean patent on this method. The reli\u00adable infor\u00adma\u00adtion that you can gain with the help of our infrared diag\u00adno\u00adsis puts you into the posi\u00adtion to min\u00adimise the risk of fail\u00adure of your elec\u00adtri\u00adcal instal\u00adla\u00adtions and to plan a state-ori\u00aden\u00adtat\u00aded maintenance.<\/p>\n
