Power and telecommunications systems are growing increasingly complex. This increases their vulnerability to lightning-related effects. Due to the high requirements for the reliability of power and telecommunications systems and the associated sensitive equipment, protection against lightning is of paramount importance. Lightning-induced effects are to be quantified in order to assess the risks and design adequate protection. This can be done with the traditional approach, which is based on the transmission-line theory and an electromagnetic-field-to-conductor coupling model, as well as with the advanced numerical techniques, such as the finite difference time-domain (FDTD) method. Interest in the FDTD method is steadily growing because of the availability of software and increased computer capabilities. This book provides an introduction to the FDTD method and its applications to studies of lightning-induced effects in power and telecommunication systems. It also contains background information on lightning, lightning models, and lightning electromagnetics. This book is essential reading for electrical engineers and researchers, who are interested in lightning surge protection studies, as well as for senior undergraduate and graduate students specializing in electrical engineering.
Direct Current (DC) transmission and distribution technologies have evolved in recent years. They offer superior efficiency, current carrying capacity, and response times as compared to conventional AC systems. Further, substantial advantages are their natural interface with many types of renewable energy resources, such as photovoltaic systems and battery energy storage systems at relatively high voltage, and compliance with consumer electronics at lower voltages, say, within a household environment. One of the core building blocks of DC-based technologies, especially at medium voltage levels, is power electronic systems technology. This cannot be emphasized enough as these units process, convert, and regulate all DC power and provide intelligence and sensing as electric power grids evolve. These advantages have led to a rise in the utilization and applications of DC in modern power systems. This includes high voltage DC transmission systems, DC distribution grids, DC microgrids, electric vehicle charging infrastructure, and the maritime industry. However, there are still substantial challenges to the operation of these systems. Examples include a lack of standards for DC based power infrastructure and DC system protection. This book presents the state of the art in medium voltage DC systems research and development, covering grid architecture, power converter design, transformers, control and protection for both traditional and mobile DC applications such as all-electric ships. This text, the first of its kind, provides essential information for researchers and research-oriented engineers working for academia, a manufacturer or utility, who wish to broaden or update their knowledge of medium voltage DC systems and associated equipment.

Electrostatic Accelerators have been at the forefront of modern technology since the development by Sir John Cockroft and Ernest Walton in 1932 of the first accelerator, which was the first to achieve nuclear transmutation and earned them the Nobel Prize in Physics in 1951. The applications of Cockroft and Walton's development have been far reaching, even into our kitchens where it is employed to generate the high voltage needed for the magnetron in microwave ovens. Other electrostatic accelerator related Nobel prize winning developments that have had a major socio-economic impact are; the electron microscope where the beams of electrons are produced by an electrostatic accelerator, X-rays and computer tomography (CT) scanners where the X-rays are produced using an electron accelerator and microelectronic technology where ion implantation is used to dope the semiconductor chips which form the basis of our computers, mobile phones and entertainment systems. Although the Electrostatic Accelerator field is over 90 years old, and only a handful of accelerators are used for their original purpose in nuclear physics, the field and the number of accelerators is growing more rapidly than ever. The objective of this book is to collect together the basic science and technology that underlies the Electrostatic Accelerator field so it can serve as a handbook, reference guide and textbook for accelerator engineers as well as students and researchers who work with Electrostatic Accelerators.
Smart grids with distributed clean energy generation, storage and prosumers are the future of energy systems. They need two-way digital communication between multiple customers and suppliers of energy, to produce, buy and sell electricity to the grid at small scales. These arrangements need a system that maintains, checks, and registers information about transactions. Blockchain technology is able to handle these requirements with smart contracts, peer-to-peer energy trading and immutable transactions. A blockchain is a digital ledger of transactions that can be accessed across the entire network of computer systems. Combined with sensors to track energy flows, blockchain can enable the smart grid. After an introduction to blockchain, chapters cover integration with IoT, IoT- and blockchain-enabled smart grids, use of sensors, security and privacy, use of machine and deep learning, energy storage and transaction, as well as use of cryptocurrencies for transactions. Written by an international team with the necessary multi-disciplinarity, this work for researchers in power systems as well as economists with related interests covers the use of blockchain technology for smart grids.

Safety in any workplace is extremely important. In the case of the
electrical industry, safety is critical and the codes and
regulations which determine safe practices are both diverse and
complicated. Employers, electricians, electrical system designers,
inspectors, engineers and architects must comply with safety
standards listed in the National Electrical Code, OSHA and NFPA
70E. Unfortunately, the publications which list these safety
requirements are written in very technically advanced terms and the
average person has an extremely difficult time understanding
exactly what they need to do to ensure safe installations and
working environments.
