What is the maximum frequency of AC used on ships?

The maximum frequency of AC used on ships is primarily 60 Hz. This frequency is widely adopted in many maritime electrical systems, particularly those operating under North American standards. Many ships, especially those that operate in regions where the power grid is 60 Hz, use this frequency for its compatibility with various equipment and systems designed to run on it.

While other frequencies, such as 50 Hz, are commonly used in different regions around the world, 60 Hz stands out as the standard in many naval applications and larger commercial vessels. Frequencies like 57 Hz and 62 Hz are not standard for maritime power systems. Adhering to a standard frequency like 60 Hz is essential for ensuring the reliability and efficiency of electrical equipment on board ships.
