Böcker av Vladimir Gurevich

The book was written by Israel's leading specialist in the field of protecting electrical equipment from the effects of an electromagnetic pulse from a high-altitude nuclear explosion (HEMP). It is the final work that completes the cycle of the author's works published earlier in his articles and books on this topic. This book details completed and tested protection devices, developed by the author on the basis of previous research, which are intended for practical implementation and industrial production. Power transformer protection, diesel-generator, control cabinets, battery chargers, UPS, telecommunication systems and much more. The book is of interest to engineers in the field of electric power, water supply, telecommunications and other critical infrastructure sectors, as well as to industry specialists, lecturers and students of universities and colleges.

How do you protect electrical systems from high energy electromagnetic pulses? This book completes the overview of systems and practices against EMPs from high altitude sources started with the previous "Protecting Electrical Equipment - Good Practices for preventing high altitude electromagnetic pulse impacts", including practical protection methods and means for evaluating their effectiveness.

This book describes specific technical problems associated with digital relays and suggests ways to solve them. It also covers the construction of functional assemblies of real relays existing in the market, drawbacks and problems of digital relays, and the danger of deliberate electromagnetic effect onto digital relays.

This book describes the arrangement, mode of action, and problems of secondary power supplies of digital protective relays, stationary accumulator batteries, battery chargers, uninterruptible power supplies, and auxiliary AC and DC power supply systems of substations and power plants. It also tackles the issues of insulation monitoring in DC systems, the problems of monitoring the integrity of a substation battery circuit, problems of voltage dips, and a number of other questions that engineers and technicians may face in working with auxiliary power systems.

The modern microprocessor based electronic equipment most vulnerable to Intentional Destructive Electromagnetic Interferences (IDEI) includes High-Altitude Electromagnetic Pulse (HEMP) in all substation equipment. However, power equipment and especially transformers are also subject to the influence of HEMP.

Discusses general problems related to the structure of overload protection systems in high voltage (HV) electrical installations and introduces a family of fresh devices based on reed switch contacts, solid-state units, hybrid technology, and automatic systems based on these components. The author also discusses applications in power engineering.

This book provides a detailed overview of the vulnerabilities of digital protection relays to natural and intentional destructive impacts. From lightning strikes, electromagnetic fields generated by operating equipment, and issues with control cable shielding to modern technical tools that realize intentional destructive impacts remotely, this first-of-its-kind text covers the latest cyber and electromagnetic threats to digital protection relays. It discusses passive means of protection, such as screened cabinets, filters, cables, special materials, and covers, as well as advanced solutions based on hardware methods.
