Safety or protective grounding is of paramount importance in safeguarding individuals from electric shock and protecting structures and industrial concerns from the potentially damaging effects of lightning and electrostatic discharges. For many electrical engineers, the concept of grounding remains somewhat ambiguous, often leading to confusion between safety grounding and neutral grounding of the power supply. The primary objective of this book is to provide the reader with a comprehensive and in-depth understanding of safety grounding, its necessity, where it is required, and the essential requirements necessary to establish an effective grounding system.

Throughout the text, the author aims to provide the reader with the necessary background to enhance their appreciation of the various national and international standards associated with safety grounding.

The book begins by summarizing the physiological effects of current on the human body and the impact of current duration. It then delves into the various methods employed to measure soil resistivity and evaluate the resistance to ground of an electrode or grounding system. The author reviews different types of ground electrodes, their geometry, and the number of electrodes used, emphasizing their influence on resistance to ground.

The book further explores the components of a ground system, including the selection of appropriate materials, methods to improve soil resistivity, the types of welds and joints used, the criteria for determining conductor cross-sections, galvanic corrosion, and a survey of the various grounding practices employed at substations and the diverse types of grounding systems used to safeguard consumers.

In addition, the book addresses the electrical aspects of safety grounding, including the principles of earthing, bonding, and fault current limiting. It discusses the role of grounding systems in protecting equipment and personnel from electric shock and minimizing the risk of fire hazards.

Furthermore, the book provides practical insights and best practices for designing and implementing effective safety grounding systems. It covers topics such as grounding grid design, fault current analysis, and the selection of appropriate grounding electrodes and conductors.

By presenting a comprehensive and detailed exploration of safety grounding, this book serves as a valuable resource for students and practicing electrical engineers seeking to enhance their understanding of this critical aspect of electrical engineering. It equips readers with the knowledge and skills necessary to design, install, and maintain safe and reliable grounding systems, ensuring the protection of individuals, structures, and equipment from the hazards of electricity.
