Sampling

If we want to know all about a material, we can find the same information integrity in the smallest piece. In order to analyze a substance for this purpose, a sufficient amount of the sample taken from that substance is called the sample.
Since the samples represent the whole of the materials, the oil sample will represent the entirety of the oil in the transformer and store. For this reason, the necessary rules should be observed and necessary care should be taken when taking samples. The person receiving the sample must know that these rules and insulation oil are very sensitive to any contamination. The most important thing when taking an oil sample is to take the sample in the right conditions and prevent foreign particles from entering the sample.
Oil analysis is done in ppm (millions of particles), especially in some of our tests. Therefore, the result of analysis of the oil sample which is not taken careful, clean and suitable conditions will be unrealistic and misleading.
