How to maintain electrical equipment on ships, level 2 training.
Ships electrical systems, differ slightly from land (shoreside) based installations.
An example of this difference is the earthing system on board ships, as you cannot physically connect to the earths surface.
Another difference, is the Voltage Frequency, in Hertz (Hz), which is typically 60Hz.
In Europe land based electricity supplies, operate at 50Hz.
Ships can be quite a hostile environment for electrical machinery onboard.
Vibration and moisture can cause breakdowns.
Vibration can cause terminals in connection boxes, to work loose.
The result could be Induction Motor, ‘Single Phasing’ fault occurrence.
Moisture resulting in electrical equipment breakdown, includes wet Induction Motor Stator Windings.
Wet Induction Motor Stator Windings, cause low Insulation Resistance.
This can result in the motor, not working.
Marine Generators can also suffer from Low Insulation Resistance.
