Through such testing, transformers’ life can be substantially increased, thus delaying new investment of replacement transformer assets. This article needs additional citations for verification. The transformer oil insulation oil of voltage- and current-transformers fulfills the purpose of insulating as well as cooling.

This page was last edited on 30 Octoberat Testing sequences and procedures are defined by various international standards, many of them set by ASTM. Thus, the dielectric quality of transformer oil is essential to secure operation of a transformer.

The lower the resulting breakdown voltage, the poorer the quality of the transformer oil.

The test method has not been changed for practical reason due to the very large number of instrumentation disseminated around the world, even if the use of stirring is now recommended.

Recently time-consuming testing procedures in test labs have been replaced by on-site oil testing procedures. It is appropriate both for acceptance testing on unused liquids at the time of their delivery and for establishing the condition of samples taken in monitoring and maintenance of equipment. 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.
