FUNDAMENTALS OF FAULT CURRENT AND GROUNDING IN ELECTRICAL SYSTEMS

fundamentals of fault current and grounding in electrical systems norman chambers

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. This book highlights the basics of these topics and gives a working overview of these systems. There are numerous grounding problems and unexplained fault conditions in electrical circuitry that are taken for granted and left unattended for extended periods. Fuses, circuit breakers, and relays provide critical protection by disconnecting unwanted current and voltage within fraction of a second to avoid damage to the circuit components. They protect cables from environmental and mechanical damages. Certain stock imagery © Thinkstock. Potential voltage can be found on the earthing conductors in processing plants, refineries, and other industrial plants.

Despite upgraded and safe methods of grounding techniques, the misconceptions on grounding and fault current are indelible in the minds of many engineers, technicians, and contemporaries. This is the foundation from which knowledge of advanced studies in electrical technology and engineering is built. Many of these potentials are due to induction, which could be due to a number of motors in use at the same time, creating a magnetic field great enough to induce a potential in nearby earth conductors. There are numerous grounding problems and unexplained fault conditions in electrical circuitry that are taken for granted and left unattended for extended periods.

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. 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. In a grounded system, normally non-current-carrying electrically conductive materials that are likely to become energized, such as building metal framing and metal water piping, shall be connected together and to the electrical supply source in a manner that establishes an effective ground-fault current path. A combination of topics in this book addresses problems that have been adversely affecting the electrical industry for years. The book clarifies common myths pertaining to a grounding electrode, short circuit, and open neutral conditions, and provides an unambiguous understanding of the theoretical and practical explanation for an effective earthing and protective system in all electrical installations. A combination of topics in this book addresses this problem and other likely problems, which have been adversely affecting the electrical industry for many years.
