What is the voltage of the ship's power system?

The ship's power system typically operates at 4160 VAC, which is a common voltage level used for distributing electrical power in larger naval vessels as well as some commercial ships. This higher voltage is preferred because it allows for efficient power transmission over longer distances within the ship, reducing energy losses that can occur with lower voltage systems.

Using 4160 VAC enables the system to support heavier electrical loads and larger equipment, such as motors and generators, which are essential for the ship’s operations. It also facilitates the integration of various systems on board, from propulsion to auxiliary machinery.

In contrast, lower voltage options such as 220 VAC or 380 VAC are generally utilized for smaller loads and specific applications like lighting and smaller appliances, while 6600 VAC is typically used in very high-power applications and is less common for standard ship power distribution.
