Electrical Discharges in Alternative Transformer Liquids: A Complete Guide

Neuerscheinung / Neuauflage Oktober 2023

Understand and deploy a sustainable alternative to mineral oils Transformers rank among the costliest and most important components in an electrical power network. Traditionally, mineral oils have been used as the primary insulating liquids for transformers, playing a crucial role in extending transformer life span. In an expanding global energy market, however, demand for sustainable alternatives to mineral oils has skyrocketed, and the search for alternative, biodegradable insulating liquids has accelerated. Electrical Discharges in Alternative Transformer Liquids is the first work of its kind to survey the available range of biodegradable insulating liquids and analyze their electrical discharging behavior. It addresses the knowledge gaps which have led to slow adoption of these insulating liquids by utility companies, despite their obvious performance benefits. The result promises to be a durable guide to monitoring transformer condition and designing transformer insulation. Readers will also find: Knowledge, behavioral observations, intrinsic aspects, various accessing parameters, and measuring methodologies concerning electrical discharges in transformer liquids Detailed discussion of topics high voltage electrical insulation, electrical machine maintenance, and more Comparative analysis of ester liquids relative to mineral oils Electrical Discharges in Alternative Transformer Liquids is ideal for researchers involved in electrical power utilities and transformer design, as well as for engineers and industry professionals in the energy industries, insulation design, and related fields.
