Dissolved Gas Analysis Of Transformer Oil PowerPoint PPT Presentations

Dissolved gas analysis determines the concentrations of certain gases in the oil such as nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrogen, methane, ethane, ethylene and acetylene

Transformer oil, a type of insulating and cooling oil used in transformers and other electrical equipment, needs to be tested periodically to ensure that it is still fit for purpose. This is because it tends to deteriorate over time. Testing sequences and procedures are defined by various international standards, many of them set by ASTM. Testing consists of measuring breakdown voltage and other physical and chemical properties of samples of the oil, either in a laboratory or using portable test equipment on site.

At Benzoil, we believe that the prevalence of the PCB contaminated transformers and equipment are on the decrease. And it is very hard to find PCB levels above the threshold of 2ppm and they are very low below 50ppm and in most cases the band is between 2 and 10ppm. Read the article for brief info.
