A DC distribution system is a type of system used to power ships and other large vessels. It works like this: A large motor called a generator turns mechanical energy into electrical energy. This electricity is then sent through electrical wires around the ship, where it provides power to things like lights, computers, and any electric equipment that the ship needs. This electric energy can also be used to power the ship’s propellers, which help it move through the water. The DC distribution system allows the ship to use the electric energy in different ways and helps it be more efficient.
