With the new oil laboratory, AOL (Accredited Oil Laboratory) in Nijmegen, the Netherlands, SMIT Transformer Service has access to its own laboratory for oil analyses. Tasks carried out here include:
- assessing the oil quality by means of tests for breakdown voltage, moisture content, interfacial tension and acidity (pH value) among other things;
- dissolved gas analysis, which assesses the condition of the transformer and which is also the basis for diagnostics in the event of faults;
- estimate of remaining service life of the transformer by assessing the dp value of the paper and the furan content of the oil, among other things.
