Index

The systems are explained in terms of their operating principles and safe working practice. The type and significance of various electrical appliances, circuits, and faults are considered and a common troubleshooting practice is examined. A wide range of onboard ancillary electrical services is described, along with detailed information on battery support, care, and maintenance. The application and operating principles of electrical propulsion are examined, as well as high voltage practice, safety procedures, and testing methods. This book will be helpful to management and operational level marine engineers, electrical engineers, and electricians, as well as students currently studying marine and electrical engineering.
