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, its application, and the essential requirements that must be met to establish an effective grounding system.

Throughout the text, the author aims to provide the reader with a solid foundation for a better appreciation of the various national and international standards associated with safety grounding. This book serves as a valuable resource for students and practicing electrical engineers seeking to enhance their knowledge and expertise in this critical area.

In the first chapter, the author delves into the physiological effects of current on the human body and the impact of current duration. It explains how electrical current can cause injury and even death, emphasizing the importance of proper grounding practices to minimize the risk of electric shock. The chapter also discusses the various methods used to measure soil resistivity and the resistance to ground of an electrode or grounding system.

The second chapter explores the various types of ground electrodes and their geometry and numbers, which play a crucial role in determining the resistance to ground. It discusses the advantages and disadvantages of different types of ground electrodes, such as driven rods, buried electrodes, and grid electrodes, and explains how they can be effectively implemented to improve the efficiency of the grounding system.

The third chapter focuses on the components of a ground system, including the grounding conductor, grounding electrodes, bonding wires, and grounding terminals. It provides detailed information on the selection and installation of these components, as well as the methods used to improve soil resistivity and reduce the risk of corrosion. The chapter also discusses the criteria for determining conductor cross-sections, the use of welds and joints, and the importance of proper grounding practices in preventing galvanic corrosion.

In the fourth chapter, the author presents a comprehensive survey of the different grounding practices used at substations and the various types of grounding systems used for the protection of consumers. It discusses the principles.

In conclusion, this book is a valuable resource for anyone interested in enhancing their understanding of safety grounding and implementing effective grounding systems. It provides a comprehensive coverage of all types of grounding requirements, from the physiological effects of current on the human body to the components of a ground system and the different grounding practices used at substations. By providing a clear and concise explanation of these topics, the author aims to empower readers with the knowledge and skills necessary to ensure the safety and reliability of electrical systems.
