Electrical ratings of transformer and alternator on ships are always done in kVA. Find out why they are mentioned in only KVA and not in KW, by understanding the concept behind the electrical systems working on ship.

A Ship cannot run on the traditional electrical systems with less voltage. The high capacity marine diesel engines and other machinery on ships require higher voltage systems to produce more electrical power. Find out the reasons for using high voltage systems on board ships.

Alternate marine power or cold ironing is a method of providing power to the ship from an external source. AMP is getting recognition around the world because of the rise in marine pollution.

Earth fault is considered very critical on board a ship. Some ships which operate at 440 V do not have any trip devices attached for a single earth fault. However when the operating voltage exceeds 3000V, it is mandatory to have a protection system which isolates when a machinery suffers an earth fault.

Electrical relay is an important part of a ship’s electrical system. Relay is a protective device which protects an electrical system from overloads and short circuits. Know more about the maintenance of electrical relay inside the article.

Inspection of busbars in main and emergency switchboards on ships is important to prevent accidents caused due to electrical faults such as short circuits, fire etc. Learn how busbar inspection is to be done on board ships by taking all necessary safety precautions.

Just like any other machinery systems on board ships, motor starter panel also needs regular maintenance to ensure smooth operations of motors. The article explains important points and procedure for motor starter panel routines and maintenance.

Like any other mechanical machinery on board ships, motors also have their own running hours, after which, the complete overhauling of the motor is to be done to ensure efficient working and performance.
