Single Phasing in Electrical Motors: Causes, Effects, and Protection Methods

For proper working of any 3 phase induction motor it must be connected to a 3 phase alternating current (ac) power supply of rated voltage and load. Once these three phase motors are started they will continue to run even if one of the three phase supply lines gets disconnected. The loss of current through one of these phase supply is described as single phasing.

How to Adjust the Load Sensors on Mooring Winches?

Mooring winches are used to tie the ship to the berth when at a port. While loading and unloading the cargo on the ship, the mooring winches…

Hazards Related to Electric Cable Insulation in Case of Fire

The insulation of the electric cable is generally made up of rubber or plastic. The amount of smoke generated by the plastic in case of fire is dependent on factors like nature of plastic, type of additive used, flame of fire and ventilation arrangement. In general most plastics produce a very dense smoke when heated. In this article we will learn about the hazards related to electric cable insulation in case of fire.

Importance of Insulation Resistance in Marine Electrical Systems

Insulation resistance is one of the critical readings of marine electrical equipment systems and serves as the best guide to indicate the health of the electrical machinery.

What are the Main Safety Devices for Main Switch Board on Ship?

The Main switch board is an intermediate installation in the ship’s power distribution circuit connecting the power generators and power consumers. The power generators on ships are auxiliary engines with alternators and the consumers are different engine room machineries such as motors, blowers etc.

8 Ways to Monitor and Measure Marine Engine Performance

The efficiency of the main engine is directly related to its performance. Mentioned in this article are eight important was to measure marine engine performance.

Electrical Safety Device: Air Circuit Breaker (ACB)

Generators onboard ships are the power suppliers for the entire vessel as they stand as the primary source of power to all running machineries including the propulsion plant. For this reason, safe and efficient running of the ship generator has to be given highest consideration. One of the important safety devices used for ship’s generator is Air Circuit Breaker (ACB).
