This is one of the greatest discoveries of all time where electrical energy – the easiest way to transfer power over great distances, is obtained from mechanical energy which in turn i... Read more
Overheating problem on Ship Extremes of temperature will affect the performance and the effective life of any electrical apparatus. Devices which depend on electromagnetic operation by shunt... Read more
Ship Rolling problem In order to reduce end-play and avoid hammering during rolling, machines should be installed with their axis of rotation either vertical or in the fore and aft direction... Read more
Secondary Essential Services These are important users that need not be in continuous operation; however they are necessary to maintain propulsion and steering, including a minimum level of... Read more
Primary Essential Services are those which need to be in continuous operation for maintaining propulsion and steering. Some of them are as follows: 1) Steering gears. 2) Pumps for controllab... Read more
The control circuit is derived directly from the ship power circuit. The control circuit provides power to the timers, relays, switches and other components: necessary to control the operati... Read more
A wiring diagram shows the detailed wiring and connections between components or items of equipment and in some cases the routing of these connections. It also shows the approximate position... Read more
A system diagram shows the main features of a system and its bounds, without necessarily showing cause-to-effect. Its main use is to illustrate the ways of operating the system. Detail is om... Read more
A block diagram shows in simplified form, the main inter-relationships of the elements in a system, and how the system works or may be operated. Such diagrams are often used to depict contro... Read more
A line diagram is constructed to show the basic operation of the electrical control circuit and explain the process, in a logical order, of the electrical sequence of events. This dia... Read more
