Protective Relays

""Protective Relays: Their Theory, Design And Practical Operation"" is a comprehensive guidebook written by Victor H. Todd in 1922. The book delves into the principles and functioning of protective relays, which are devices that detect faults in electrical power systems and trigger protective actions to prevent damage or failure. The book covers the theory behind protective relays, including the physics of electric circuits, electromagnetism, and the behavior of electrical faults. It also explains the design and construction of different types of relays, such as electromagnetic, thermal, and static relays, and discusses their advantages and limitations. In addition, the book provides practical guidance on the installation, testing, and maintenance of protective relays. It includes detailed descriptions of relay circuits, wiring diagrams, and examples of relay settings and coordination. The book also covers the use of protective relays in various applications, including power transformers, generators, motors, and transmission lines. Overall, ""Protective Relays: Their Theory, Design And Practical Operation"" is a valuable resource for electrical engineers, technicians, and anyone involved in the design, operation, and maintenance of power systems. Its clear explanations, diagrams, and examples make it accessible to both beginners and experienced professionals.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
