Book Description
A comprehensive reference and guide on the usage of the alternative dielectric fluids for transformer insulation systems Liquid-filled transformers are one of the most important and expensive components involved in the transmission and distribution of power to industrial and domestic loads. Although petroleum-based insulating oils have been used in transformers for decades, recent environmental concerns, health and safety considerations, and various technical factors have increased the need for new alternative and biodegradable liquids. Alternative Liquid Dielectrics for High Voltage Transformer Insulation Systems is an up-to-date reference and guide on natural and synthetic ester-based biodegradable insulating liquids. Covering the operational behavior, performance analysis, and maintenance of transformers filled with biodegradable insulating liquids, this comprehensive resource helps researchers and utility engineers expand their knowledge of the benefits, challenges, and application of ester-filled transformers. In-depth chapters written by experienced researchers addresses critical topics including transformer condition monitoring, high voltage insulation testing, biodegradable insulating material processing and evaluation, and more. A unique and significant contribution to existing literature on the subject, this authoritative volume: • Covers condition monitoring, diagnostic testing, applications, maintenance, and in-service experiences • Explores current challenges and future prospects of ester-filled transformers • Discusses significant research progress and identifies the topics in need of further emphasis • Compares the differences and similarities between mineral oils and ester liquids • Includes in-depth behavioral observations and performance analysis of ester-based insulating liquids Alternative Liquid Dielectrics for High Voltage Transformer Insulation Systems: Performance Analysis and Applications is a must-have reference for utility engineers, electrical power utilities, transformer owners, manufacturers, and researchers.

Book Description
Written by leading experts in the field, the first edition of this textbook was the first of its kind to address numerous potential applications such as the technology of high-voltage insulation in pulsed inhomogeneous fields, and applications related to cavitation development in liquid dielectrics, treatment of different materials and plasma medicine. This second edition addresses the development of the theory over the past few years and features extensive revisions, as well as some expanded chapters. A new inclusion is an explanation of how the critical pressure at which cavitation is initiated is determined according to the surface tension coefficient at the boundary of small nanovoids and microbubbles. Discussion of the quantum mechanical nature of the cavitation inception in liquid helium is also provided, along with the derived values of critical negative pressure for the appearance of cavitation, and its characteristics at low temperatures.

Book Description
This book describes the state-of-the-art use of biological insulating liquids in detail. In recent years, more and more transformers filled with esters have been put into operation. This is because people recognize the benefits of ester liquids in terms of their fire safety (high flash and fire points) and environmental characteristics, judging from their biodegradability, their low CO2 footprint (only valid for natural ester) and their beneficial interactions with solid insulation, etc. One of the main reasons is that the water adsorption and absorption characteristics of these liquids are excellent and very different compared to mineral oil. The today’s discussion about climate change and global warming is an additional driver for using natural ester. Another advantage is that transformers filled with biological insulating liquids can operate with an overload of up to 150%. This is advantageous in the case of volatile energy generation from wind and solar power and in the supply of electrical energy for electromobility. Liquid inside electrical equipment is the lifeblood that serves both as a dielectric and a cooling medium. Some properties of these liquids differ from mineral oil, which had to be considered in the transformer design. The dielectric liquid is always in direct contact with transformer materials; therefore, the interaction should be very well understood, especially when retrofilling an existing mineral oil filled device. There are several natural ester fluids derived from various seeds and fruits on the market, and their properties may differ more or less. In the book, the most important properties of the different biological insulating fluids and mineral oil are compared. Ester fluids have already found their way into various standards. The condition of the device can be verified very well from the contents of the insulating liquids. For analysis and testing, the same equipment and devices that are commonly used for mineral oil are used for ester liquid. The chemical and physical behaviors of ester fluids compared to mineral oil are different. This must always be considered when interpreting test results stemming from ester fluids. The book is a guideline for students, original equipment manufacturers, users, laboratories and authorities in the use of biological insulating liquids.
