Abstract Since its introduction in the late 1990s, the use of vegetable oil as a transformer dielectric has become more common in the power industry. Some of the advantages of using vegetable oil rather than conventional mineral oil are that vegetable oil is nontoxic and more biodegradable and has a fire point that is approximately 200°C higher. Much research on the use of such fluids has been performed over the years, focusing on topics such as dielectric strength [1]–[3], aging [4], and dissolved gas content [5]–[8]. The next step is to assist the users of vegetable-oil-filled transformers in monitoring the condition of the transformers and to recognize oil test results that can be considered normal, although they differ from the corresponding results for mineraloil dielectrics. In this article the test results for a new normally operating power transformer, covering the first two years of its service life, are presented. It is hoped that these results will assist power industry personnel in recognizing the characteristics of normal operation of vegetable-oil-filled transformers.Preliminary results were published in our previous article [9]
