ABSTRACT
Since the —rst electrical light was installed on the American ship Columbia in 1880 and the subsequent denial of insurance due to safety fears of electrical —re, the electrical power plants in modern ships have grown in size and complexity with the growing demands on ship size, speed, economy, safety, comfort, and convenience. From the original electrical power of a few kilowatts at 120 V, some of today’s navy and cruise ships require an electrical load of over 100 MW at a voltage of 11 kV or higher.
