AB  - Numerous investigations are being carried out to further examine the features of the ester fluids because of their impressive performance as an alternative to traditional mineral oils in the power transformer. Given that these materials can be used in so many industrial equipment, not to mention the power transformer, environmental impact was a key research focus. Several techniques for evaluating the biodegradability of ester fluids used in electrical transformers have been illustrated in this paper, providing information about their potential as greener substitutes for traditional mineral oil-based insulating fluids. Ester fluids, particularly those made from vegetable oils, have become more popular because of their improved biodegradability and less environmental impact. As a result, the case of interest concerned the methods and rates of ester fluid biodegradation in various environmental settings as well as the impact of ester fluid type on biodegradability. This review emphasizes the necessity for continued research to improve the formulations and environmental management techniques of ester fluids used in transformer applications because of their biodegradability. This is important for developing sustainable power distribution systems. © 2023 IEEE.

AB  - Power transformer insulation has been getting a wide interest ever since this technology was put in service. Until these days many studies to develop the transformer insulation are being held. The purpose of this study is to investigate the dielectric constant of some liquids that can be used as an insulation material either specifically for the power transformer or for other applications using the high frequency and vector network analyzer device. Applying the test material as a dielectric in a model that simulates the coaxial cable design, the dielectric constant was measured using the reflected wave spectrum of a short-circuited coaxial line. As this is a new method of measurement; the results were compared with the actual complex dielectric constant values for each liquid to evaluate the accuracy of the experiment and check if there a chance of improvement. Further studies can be carried using this method which opens the way to further study the dielectric properties of different materials. © 2023 IEEE.
