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. The test procedure is performed in a specified apparatus, where the oil sample is subjected to an increasing AC electrical field until breakdown occurs. As transformer oil deteriorates through aging and moisture ingress, transformer oil should, depending on economics, transformer duty and other factors, be tested periodically.

To assess the insulating property of dielectric transformer oil, a sample of the transformer oil is taken and its breakdown voltage is measured. Recently time-consuming testing procedures in test labs have been replaced by on-site oil testing procedures.
The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. A blood donation campaign organized to mark the anniversary, was held at CEB Head Office and several other branch offices on 1 st November The transformer oil insulation oil of voltage- and current-transformers fulfills the purpose of insulating as well as cooling.
The lower the resulting breakdown voltage, the poorer the quality of the transformer oil. Web Solution by slt.
