Vegetable oils, an alternative to mineral oil for power transformers- experimental study of paper aging in vegetable oil versus mineral oil

Maria Augusta G. Martins

Abstract

This article compares the thermal aging of insulating paper in mineral oil with that of paper in vegetable oil over the temperature range of 70 to 190°C and shows that the use of vegetable oil as an insulating liquid is a very promising option.
