Marine Engineering Series: Marine Electrical Practice, Sixth Edition focuses on changes in the marine industry, including the application of programmable electronic systems, generators, and motors. The publication first ponders on insulation and temperature ratings of equipment, protection and discrimination, and AC generators. Discussions focus on construction, shaft-drive generators, effect of unbalanced loading, subtransient and transient reactance, protection discrimination, fault current, measurement of ambient air temperature, and basis of machine ratings. The text then examines AC switchgear, automatic voltage regulators, DC generators, and DC switchgear. Topics cover switchgear for parallel-operated generators, protection against short-circuit, field regulators and the effect of tropical temperatures, compound-wound generators, power generators, loading sharing, voltage comparison circuit, and amplifier and condition circuit. The manuscript surveys electric cables, motors, motor control gear, semiconductors, storage batteries, and battery control gear. Concerns include calculations to determine the size of battery required, types of storage batteries, rectifiers, tunnel diodes, maintenance of control gear, overload protection, insulation, sheathing, and flexible cords and cables. The publication is a dependable reference for marine engineers and researchers interested in marine engineering.
