Available in PDF, EPUB and Kindle. Book excerpt: "Reliable power transmission is a main factor in designing transmission and distribution lines. Contaminated environments significantly reduce the performance of outdoor insulators in which the accumulation of contamination eventually leads to a complete flashover. The main factors that lead to contamination flashover include, operating voltage, humidity level and temperature. Contamination flashover happens when soluble or non-soluble deposits cover the surface of the insulator, which results in a reduction of the surface resistance. The flashover event is the main problem that affects the life-time of the insulators reducing the security and reliability of the power transmission system. Controlling the risk of flashover is practically done by cleaning and replacing heavily polluted insulators. However, there is no standard technique for scheduling cleaning or maintenance of outdoor insulators, which in some cases can extend for hundreds of kilometers. To make this process as efficient as possible, many researchers are trying to develop techniques for flashover prediction. In the past, some researchers used the leakage current to predict the contamination level on the surface of ceramic and porcelain outdoor insulators. This can help as a mean to warn transmission power operators about the advent of contamination flashover. However, there have been few researches to predict the contamination levels on the surface of non-composite or polymer insulators. This work aims to develop a practical technique to monitor and evaluate the surface condition of non-composite by predicting the soluble contamination level. In this research, the leakage current was used to predict the soluble salt deposit on the surface of polymer insulators. Based on this prediction the surface condition of the insulator was evaluated."--Abstract.

This book was released on 2012-11-11 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composite insulators have been in service in electric power networks successfully for more than 40 years, and now up to the highest operating voltages. The present book extensively covers such insulators with a special focus on today’s prevalent material, which is silicone rubber. It includes a detailed description of the electrical and mechanical characteristics of composite insulators, their material properties, their design as well as typical applications and service experience. Particular attention is given to the mechanical behavior of long rod and post insulators, insulated cross-arms, interphase spacers and hollow core apparatus insulators. The state of the art on manufacturing procedures and the selection and dimensioning of the necessary power arc and corona fittings is presented as well as evaluation tests of “old” insulators, i.e. insulators after many years in service. The closing chapter deals with an up to date overview of test procedures and IEC standards. The selection and the contents of the various subjects covered in this book are based on the authors’ more than thirty years of experience with a renowned European manufacturer of composite insulators and string hardware. Their long and active participation in the relevant CIGRE and IEC working bodies adding to this experience. This book is therefore addressed to practicing engineers from electric utilities and the industry, as well as to academic professionals.

This book was released on 2021-08-30 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electrical demands in several countries around the world are increasing due to the huge energy requirements of prosperous economies and the human activities of modern life. In order to economically transfer electrical powers from the generation side to the demand side, these powers need to be transferred at high-voltage levels through suitable transmission systems and power substations. To this end, high-voltage transmission systems and power substations are in demand. Actually, they are at the heart of interconnected power systems, in which any faults might lead to unsuitable consequences, abnormal operation situations, security issues, and even power cuts and blackouts. In order to cope with the ever-increasing operation and control complexity and security in interconnected high-voltage power systems, new architectures, concepts, algorithms, and procedures are essential. This book aims to encourage researchers to address the technical issues and research gaps in high-voltage transmission systems and power substations in modern energy systems.
