The central section of the main switchboard is used for the control of the main generators. The switchgear cubicles on either side of the generator panels are used for essential se... Read more
Regular inspection and the correct maintenance of generators and their associated control gear is essential to prevent failure and inefficient operation. Always ensure that the gen... Read more
An undervoltage (U/V) release mechanism is fitted to all generator breakers and some main feeder circuit-breakers. Its main function is to trip the breaker when a severe voltage di... Read more
The general term “overcurrent” applies to a relatively small increase over the full load current (FLC) rating (e.g. due to mechanical overloading of a motor) rather tha... Read more
Ships’ staff must operate equipment in a safe manner and maintain it in a safe condition at all times. Failure to do so will cause danger with serious consequences arising. K... Read more
Ship’s large power equipment and processes utilise high forces. Electrical, mechanical, thermal and chemical changes produce the desired operation. Very high values of ship voltage... Read more
It may well save time and trouble to convert the ship wiring diagram into a much simpler and more useful circuit diagram. When converting a ship’s wiring diagram into a circuit dia... Read more
An overview of a ship’s electrical system is presented and describes various types of circuit diagrams used in electrical work. Electrical calculations, safety precautions, c... Read more
Ship switches are usually very reliable electrical devices. Most switches on vessel are designed to operate 100,000 times or more without failure if the voltage and current ratings... Read more
Embossed metal tags are used to identify cables throughout the vessel. The tags are located at the distribution panel and the component. Tags are also attached to the cables where... Read more
