Ship electrical diagrams are schematic illustrations used to represent any ship electrical system ranging from single line power distribution systems to ship main power and auxiliary circuits for control, signaling and monitoring.
Ship electrical diagrams are composed of symbols representing electrical devices, lines representing conductors or wires for interconnections and can include:
Symbols that identify the electrical equipment, its component parts and connections
- Ship electrical equipment and terminal markings
- References at or near the representations of equipment and circuit connectors which indicate where in the schematic diagram
- Corresponding part of the equipment or the continuation of the circuitry can be found, ie in which section, square or possibly which page.
These features are usually sufficient to explain the circuitry and its mode of operation and can be used to follow through the circuits when tracing a fault.
For the ship engine department, it is important to read and understand them and to use them as an aid while troubleshooting electrical Installations.
