Synthetic esters are such organic compounds that are being developed by synthesizing acids and alcohols. Synthetic esters are available in various chemical compositions depending on the acids and alcohols used for synthesis. Synthetic esters are biodegradable and are developed for high thermal performances with low viscosity and better oxidation stability. Moreover, ester group insulation oils participate actively in hydrolysis, which resists the rate of degradation of the oil.

The complete journey of the liquid dielectrics concerning the transformer insulation technology is outlined and discussed by I. Fofana [30] and U. Mohan Rao et al. [31, 32]. Given the fact that the high demand for alternative biodegradable insulating liquids allowed researchers focus on the performance analysis and behavior of ester liquids. Researchers across the globe have reported numerous studies; this book has been framed to give a complete overview of ester liquids' performance, behavior, and compatibility for current and foreseen transformer insulation technology. To accomplish the same, various topics have been organized in the subsequent chapters of this book. Authors of different chapters aimed to discuss particular topics in a detailed manner. Some fundamental concepts concerning the ester liquids have been spanned to multiple chapters. This is due to the fact that different chapters have been prepared by different research groups. However, due care is taken not to duplicate the sections and technical viewpoints. Therefore, this book editors and authors expect that this book would be useful for transformer owners, utility engineers, and researchers concerned with transformer insulation technology.
