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
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
Power currents (AC) can be measured simply by using a clampmeter that acts as a current transformer. The instrument’s tongs are clipped round a single insulated conductor and the c... 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
The induction motor has been a reliable workhorse of the industry ever since it was invented by Nikola Tesla in 1888. It is the most widely used motor because of its simple, brushl... Read more
Of the total electrical energy generated worldwide, about 58% is used by all motors combined, about 7% for lighting, and the remaining 35% for heating and other uses.Major types of... Read more
The synchronous generator excitation system is designed to produce the rotor magnetic field that can be varied to control the voltage and reactive power of the ship generator.In mo... Read more
If the frequency of Generator 1 were to be maintained constant regardless of its load, if Generator 1 were made infinitely stiff, its frequency droop under load is eliminated, and... Read more
Is there a powerful but safe lithium-ion battery for the marine industry? And are there performance improvements for marine propulsion, diesel engine starting, or generator-off ene... Read more
