Dreams are dreamt in life, but a few with determination are realized and accomplished by us. This book on the topic of “Alternative Dielectric Liquids for Transformer Insulation Technology” is the outcome of that determination I had developed since my acquaintance waith Professor Issouf Fofana at the International Research Center on Atmospheric Icing and Power Network Engineering (CenGivre) at the University of Quebec at Chicoutimi (UQAC). Finally, two and a half years later on the second day of April 2021, I am happy to write this editorial on the realization of this book, which has been enriched with contents derived out of paramount discussions I have had with Professor Fofana at various occasions. In the early 2019, we initiated the idea of delivering a short e‐book to the scientific community on the modern knowledge of ester liquids and potential challenges on new‐generation insulating fluids. The development of this project kicked off in the mid‐2019s after Professor Fofana revitalized the IEEE DEIS Technical committee of Liquid Dielectrics (TCLD) as a technical committee chair. It is also my immense pleasure and pride to have contributed to the TCLD activities as an invited committee member. Further around late 2019, Professor Fofana and I decided to implement the book project and an international study group under the umbrella of the TCLD by inviting potential research groups to contribute. In the second quarter of 2020, I had a pleasure to propose the idea of this book volume to the Wiley‐IEEE press, during which I had the privelage to invite Professor Ramanujam Sarathi from the Indian Institute of Technology, Madras, India, who joined as a fellow coeditor for the present edition. This book includes edited chapters contributed by renowned scientist from around the world from countries, namely, Australia, Canada, China, India, New Zealand, Poland, Spain, Sweden, Turkey, and United Arab Emirates. Initially planned to be published by the end of 2020, this book, like many other projects worldwide, has suffered a slight delay due to the influence of the COVID‐19 global pandemic.
Increasing requirements of electricity at an alarmingly rapid rate due to population and industrial growth have caused severe energy crises throughout the world. The shortage of fossil fuels (such as coal, crude oil, and natural gas) amplifies this crises, by progressively diminishing the availability of conventional methods of power generation. In addition, emission of harmful greenhouse gases (by‐products of fossil fuels) discourages further consideration of conventional resources as a long‐term future solution. The growing concern over issues related to energy security and global warming has resulted in the evolution of renewable energy resources and potential alternatives with environmental and economic benefits. The recent Paris climate accord signed by 195 countries, dealing with the mitigation and adaptation of greenhouse gas emissions and the divestment from fossil fuels, has spurred the exponential development and demand of renewable energy‐based technologies. One such green and alternative candidate to mineral insulating oil (extracted from crude petroleum stocks) is ester‐based dielectric liquid. Therefore, this book is dedicated to reach the readers across the globe in transferring the contemporary knowledge on these new dielectric fluids. The following paragraphs provide an insight of the scientific contents of the book
