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
Global Transformer Oil Testing key players include SGS, Munich Re, Bureau Veritas, ALS, Veritas, etc. Global top five manufacturers hold a share over 35%.
Europe is the largest market, with a share about 30%, followed by North America and China, both have a share over 35 percent.
In terms of product, Dielectric Breakdown Voltage is the largest segment, with a share over 20%. And in terms of application, the largest application is Mineral Oil, followed by Non Mineral Oil.
