Grounding Electrical Distribution Systems

by Gregory P. Bierals

The first concern and the most important reason for proper grounding techniques are to protect people from the effects of ground-faults and lightning. Creating an effective ground-fault current path to assure the operation of overcurrent protective devices on solidly grounded systems and to limit the voltage-rise on equipment frames during fault condition is of paramount importance. The next concern is building and equipment protection. In this case, providing low impedance bonding and grounding paths between the system source, the electrical service and downstream equipment will serve to limit hazardous voltages due to faults and especially, lightning, A low resistance-to-ground system will serve to limit the voltage rise on systems and equipment. But of equal importance is the length of the grounding electrode conductor. It is critical to limit the length of this conductor due to the increased impedance of lightning currents. And finally, a properly installed grounding system will minimize the effects of electrical noise on sensitive circuits and stabilize the voltage-to-ground during normal operation. This volume has extensive information on grounding electrical systems and equipment. This information includes the following topics: System Grounding Equipment Grounding Bonding The Grounding Electrode System Solidly Grounded Systems Impedance Grounded Systems Grounding Separately-Derived Systems Calculating Ground-Fault Currents Conductor Insulation Withstand Ratings Conductor Fusing or Melting Currents Functional Grounding Lightning Protection Readership: Anyone involved with designing a proper grounding system that will serve to protect people and equipment from the effects of ground faults and lightning. And to design a proper grounding system for special applications, including Solar and Wind Powered Systems.

This course will offer an in-depth exploration of these essential applications in the context of solar renewable and battery storage systems.This text includes an in-depth study of the terms and definitions applicable to grounding and bonding. In addition, there is a complete analysis of single-phase and three-phase distribution systems, beginning at the supply transformer and terminating at the utilization equipment supplied by a branch circuit. This summary includes the proper system and equipment grounding and bonding methods. In addition, the lightning protection system is explained in detail (NFPA 780).In the final chapter there is a 50 question quiz and an answer key to further enhance the reader’s understanding of this subject.

Groundwater Development and Management: Issues And Challenges In South Asia

by Pradip K. Sikdar

This book deals with the challenges for efficient groundwater management, with a focus on South Asia and India, providing a balanced presentation of theory and field practice using a multidisciplinary approach. Groundwater of South Asia is increasingly confronted with overuse and deteriorating quality and therefore requires urgent attention. Management of the stressed groundwater systems is an extremely complex proposition because of the intricate hydrogeological set-up of the region. Strategies for sustainable management must involve a combination of supply-side and demand-side measures depending on the regional setting and socio-economic situations. As a consequence, the challenges of efficient groundwater management require not only a clear understanding of the aquifer configuration, but also demand for the development of a comprehensive database of the groundwater occurrences and flow systems in each hydrogeological setting. In addition, drilling and well construction methods that are appropriate to different hydrogeological formations need to be implemented as well as real-time monitoring of the status of the groundwater use. Also corrective measures for groundwater that is threatened with depletion and quality deterioration need to be installed. Finally, the legal framework of groundwater needs to be rearticulated according to the common property aspect of groundwater. These challenges should revolve around effective groundwater governance by creating an atmosphere to support and empower community-based systems of decision-making and revisit the existing legal framework and groundwater management institutions by fostering community initiatives.This book is relevant for academics, professionals, administrators, policy makers, and economists concerned with various aspects of groundwater science and management.

Groundwater Geophysics in Hard Rock

by Prabhat Chandra Chandra

In hard rock terrain, shallow water wells generally have a poor to moderate yield. Sinking wells deeply to tap yielding fracture zones often backfires, because the borehole may miss the saturated fracture zones at depths. A wrong approach to groundwater exploration in hard rock has therefore often led to unnecessary recurring expenditures and waste
