| diagram of earthing system: FUNDAMENTALS OF FAULT CURRENT AND GROUNDING IN ELECTRICAL SYSTEMS HALDEN MORRIS & NORMAN CHAMBERS, 2014-06-30 This book seeks to explain in simple terms the behavior of fault current through the general mass of earth, the origin of short circuit current and its value, and how a circuit breaker operates. The drawings are unique and allow the reader to visualize the behavior of a fault current. The book clarifies common myths pertaining to a grounding electrode, short circuit, and opens neutral conditions, and provides an unambiguous understanding of the theoretical and practical explanation for an effective earthing and protective system in electrical installations. There are numerous grounding problems and unexplained fault conditions in electrical circuitry that are taken for granted and left unattended for extended periods. Potential voltage can be found on the earthing conductors in processing plants, refineries, and other industrial plants. A combination of topics in this book addresses problems that have been adversely affecting the electrical industry for years. There are a number of systems in the electrical industry that are common in the workplace but are not understood by the average workman who has to work with these systems daily. Systems such as ungrounded systems, clean earthing systems, motor controls, resistance grounding, lightning protection systems, and Intra earthing systems are all common systems; however, the knowledge base of these systems is very limited. This book highlights the basics of these topics and gives a working overview of these systems. The book also discusses the principle of operation of the ground fault circuit interrupter (GFCI). It is expected that the information provided will allow the reader to visualize various types of GFCIs and the principle of operation without necessarily having to revert to other text. |

| diagram of earthing system: Contact Lines for Electric Railways Friedrich Kiessling, Rainer Puschmann, Axel Schmieder, Egid Schneider, 2018-01-03 Electric traction is the most favourable type of power supply for electric railways from both an ecological and an economic perspective. In the case of urban mass transit and high-speed trains it is the only possible type of traction. Its reliability largely depends on contact lines, which must operate in all climatic conditions with as high availability and as little maintenance as possible. Extreme demands arise when overhead contact lines are required to provide reliable and safe power transmission to traction vehicles travelling at speeds in excess of 250 km/h. The authors have used their worldwide experience to provide comprehensive descriptions of configuration, mechanical and electrical design, installation, operation and maintenance of contact lines for local and long-distance transportation systems, including high-speed lines. In this book, railway company professionals and manufacturers of contact line systems, students and those embarking on a career in this field will find practical guidance in the planning and implementation of systems, product descriptions, specifications and technical data, including standards and other regulations. Special emphasis is laid on the interaction of the individual components of power supply, especially between contact lines and pantographs. Since large sections of the book are dedicated to system aspects, consultant engineers can also use it as a basis for designing systems as well as interfaces to other subsystems of electric railway engineering. The contents of the book are rounded off by examples of running systems. |
