This book has been designed to give plant operators, electricians, field technicians and engineers a better appreciation of the role played by power system protection systems. An understanding of power systems along with correct management, will increase your plant efficiency and performance as well
as increasing safety for all concerned. The book is designed to provide an excellent understanding on
both theoretical and practical level. The book starts at a basic level, to ensure that you have a solid grounding in the fundamental concepts and also to refresh the more experienced readers in the
essentials. The book then moves onto more detailed applications. It is most definitely not an advanced treatment of the topic and it is hoped the expert will forgive the simplifications that have been made to the material in order to get the concepts across in a practical useful manner.
The book features an introduction covering the need for protection, fault types and their effects,
simple calculations of short circuit currents and system earthing. The book also refers to some practical work such as simple fault calculations, relay settings and the checking of a current transformer magnetisation curve which are performed in the associated training workshop. You should be able to do these exercises and tasks yourself without too much difficulty based on the material covered in the book.
This is an intermediate level book – at the end of the book you will have an excellent knowledge of the principles of protection. You will also have a better understanding of the possible problems likely to arise and know where to look for answers.
In addition you are introduced to the most interesting and ‘fun’ part of electrical engineering to make your job more rewarding. Even those who claim to be protection experts have admitted to improving their knowledge after attending this book but at worst case perhaps this book will perhaps be an easy refresher on the topic which hopefully you will pass onto your less experienced colleagues.
We would hope that you will gain the following from this book:
• The fundamentals of electrical power protection and applications
• Knowledge of the different fault types
• The ability to perform simple fault and design calculations
• Practical knowledge of protection system components
• Knowledge of how to perform simple relay settings
• Increased job satisfaction through informed decision making
• Know how to improve the safety of your site.
Typical people who will find this book useful include:
• Electrical Engineers
• Project Engineers
• Design Engineers
• Instrumentation Engineers
• Electrical Technicians
• Field Technicians
• Electricians
Preface
• Plant Operators
You should have a modicum of electrical knowledge and some exposure to electrical protection systems to derive maximum benefit from this book.
