How the grounding is done in ships and aeroplane
I should have read this 8 years ago. My friend asked me to design a simple earth-leak meter and told me it was for 24V DC system. Later he told me that it was used in a small ship sailing along the rivers.Hola Rohit,
Aboard vessels, not all circuits have their neutral, electrically connected to the hull. The neutral is isolated. It is related to them being essential to safety / their voltage.
Not as a seaman, I had the chance to do some work on board of two or three "wave piercing" ferries (fast ferries sailing at around 55 knots in open waters). Their hull is made of Aluminum and the builders took lot of pain to keep the electrical systems isolated from it to avoid corrosion due to undesired currents. They do have a quite sophisticated system to measure any leakage to the hull.
