Storing electrical energy for later use

Measuring and monitoring power consumption

Protecting the network from overload and short circuits

Distributing electricity throughout the ship

AC and DC both flow in one direction.

AC is only used in batteries, while DC is used in power transmission.

DC flows in only one direction, while AC periodically reverses direction.

AC flows in only one direction, while DC periodically reverses direction.
