• Gebundenes Buch

Produktbeschreibung

This book delves into the diverse prerequisites for grounding and earthing in contemporary ship power systems, addressing the evolving landscape of ship design influenced by power electronics The introduction of transformative technologies such as variable frequency drives and electric propulsion systems has heightened the complexity of shipboard grounding systems. This complexity necessitates accommodation for robust electronic systems, extending the focus beyond traditional grounding aspects to include common mode grounding and its profound design implications. Engineers now require a comprehensive guide to navigate the intricacies of shipboard electric power systems. To meet this imperative, Design of Shipboard Power System Grounding/Earthing provides an in-depth exploration of the subject. It offers a step-by-step initiation into the grounding process, supported by numerous case studies for enhanced comprehension. Aligned with both US and international standards, this book serves as an essential resource for engineers engaged in the design and implementation of shipboard power systems. Key highlights for readers encompass meticulous comparisons between terrestrial power system grounding and shipboard power grounding, as well as comprehensive discussions on high resistance grounding, shipboard AC system grounding requirements, DC system grounding, and more, including common mode grounding and earthing. The inclusion of abundant engineering drawings supports significant case studies, enhancing the practical application of the material. Designed to cater to a broad audience, Design of Shipboard Power System Grounding/Earthing is invaluable for readers involved with shipboard electrical systems, including shipbuilders, ship designers, ship operators, and those in regulatory bodies such as the Navy, USCG, ABS, among others. This resource is also well-suited for academicians, particularly final-year undergraduate and graduate students in marine electrical engineering programs.
