Description

Cyber and Electromagnetic Threats in Modern Relay Protection provides a detailed overview of the vulnerabilities of digital protection relays to natural and intentional destructive impacts, including cyber attacks and electromagnetic intrusions. 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.


Emphasizing the importance of relay protection to the infrastructure of a country, this book:




Explains how technological advances in the power industry, like the smart grid, can create dangerous vulnerabilities
Discusses traditional passive means of protection, such as screened cabinets, filters, cables, special materials, and covers
Describes advanced protective solutions based on hardware methods


Cyber and Electromagnetic Threats in Modern Relay Protection is a valuable reference for engineers involved in the design, development, and use of relay protection. It is also beneficial for scientists, researchers, and students of vocational schools and technical universities.
