A vessel has an extensive electrical system designed to carry out more functions than can be found in a small community. Lighting, instrument panels, steering systems, stoves, and... Read more
To properly understand how these different grounds fit into the vessel’s electrical system, the word “ground” must be understood as it was originally used. Decade... Read more
The distribution system is an extension of the generator. All electrical loads are connected in parallel with the generator terminals through connection points (nodes) at the switc... Read more
The fuse is a piece of wire which can carry a stated current; if the current rises above this value it will melt. If the fuse melts (blows) then there is an open circuit and no cur... Read more
It’s all to do with better chemistry of the battery technology – Li-ion has got different layers, so there are different types of chemistry you can use to put Li-ion batteries toge... Read more
This is when equipment is left untouched until a breakdown occurs. At this time, the equipment is repaired or replaced and any other specified maintenance procedure carried out. Th... Read more
All equipment is subject to wear and tear and will eventually reach the end of its useful life and need to be replaced. As equipment nears the end of its safe working life, its con... Read more
Like all motors, the induction motor starting directly at full line voltage draws high inrush current several times greater than the normal rated current. Ship electrical motors hi... Read more
This type of Ship’s Diagram includes basic circuit logic. Electrical components are confined by ‘series and parallel’ rules. These rules are essential in the understanding of... Read more
