The function of a ship’s electrical distribution system is to safely convey the generated electrical power to every item of consumer equipment connected to it. Probably the m... Read more
Power currents (a. c.) can be measured simply by means of a clamp meter which acts as a current transformer. The instrument tongs are clipped round a single insulated conductor... Read more
Electronic diodes, and other semi-conductor devices with p-n junctions (e.g. the base-emitter of a transistor) can be tested using a digital type instrument using the following pro... Read more
Ideally insulation resistance measurement on ship electrical machine is while the machine is hot? Insulation becomes more leaky (its IR value falls) at high temperatures. So testin... 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
There are various types of diagram which attempt to show how an electrical Circuit operates on ship. Symbols are used to represent the various items of equipment. The shipbuilder p... 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
Color coding allows the Electrical engineer ETO to follow electrical circuits throughout a vessel without having to physically touch each cable. The color can be continuous through... Read more
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
