Fresh Perspective for Marine Electrical Distribution Free Essay Example, 4250 words

Direct current (DC) is an alternative to alternating current (AC). Electronic circuits are mostly operated and run by low-voltage DC, and this is applicable and ideal for equipment and machines in large ships. A direct current is also produced by an electronic circuit, with capacitors, resistors, and transformers, to convert the alternating current. DC has many advantages compared with AC. One of the most significant advantages is the absence of inductance losses and harmonic problems. Certainly, DC systems would be preferred over AC systems if the advantages of AC devices such as transformers, three-phase induction, and synchronous machines were not present. AC electromagnetic machines do no face any real competition because of the poorer performance and higher maintenance of any such alternatives. AC electromagnetic machines are unlikely to be replaced with anything having compatible performance characteristics in the near future. The combination of an electric generator with a di esel engine or a gas turbine is perhaps the most effective way to produce electrical power for the foreseeable future. DC generators no longer have a real place in large marine electrical systems, as they are heavy, expensive, and can provide only limited voltage, imposed by the limitations of commutators.
