Agreements and Disagreements in the Selection of Natural Esters for Power Transformers

The “critical dielectric fluid,” or CDF, made of natural esters encourages the need for power transformers to meet CIGRE and IEEE requirements. The areas of dielectric qualities including dissipation factor, moisture, oxidative stability, and partial discharges are where there is the most dispute over the capabilities of the natural ester. Modified versions of natural esters are introduced into the systems to preserve the transformers' dependability since they decrease practical failure. Natural esters exhibit remarkable agreement with the solid insulation in terms of insulating life by lowering the formation of dissolved gases. This critical analysis was primarily designed to help the researcher comprehend the reasons behind the discrepancy in CDF choice about CDF's capacity to exhibit the characteristics of superior insulating commercial fluid (SICF).
