How water helps monitor oil aging?
Impact of moisture on insulating liquids is universal regardless of their type – mineral oil, natural and synthetic esters.
The validity of recommended values of oil parameters from standards are doubtable because there is a lack of statistical backup or explicit information on how those values were determined.
Dr. Oleg Roizman, our columnist in his column ‘Water in transformer’ in our October edition explains not only how moisture affects the quality of the insulating liquid, but also how online sensing of moisture parameters can be used in continuous monitoring of oil condition, rate of oil deterioration and aging of both oil and paper insulation, because, apart from being an insulator and a coolant, oil is also an information carrier.
