Hi there! We have discussed in a previous article the theory behind the electrical breakdown in liquids applied to insulated oils inside power transformers.

We found that contaminants inside the oil are the main cause for electrical breakdown inside oils, therefore since mineral oils degrade over time, it is expected to eventually see contaminants inside the oil.

In order to ensure that the quality of the oil remains within acceptable values, it is necessary to develop quality tests to determine if it is necessary to schedule maintenance or not.
