Power factor is a measure of the efficiency of an electrical system, and it is defined as the ratio of the active power (or real power) to the apparent power. A low pf can result in a range of problems, including higher energy costs, reduced system capacity, and increased equipment wear and tear. PF-power factor, […]
High Voltage advantages on ship have been discussed in this article, as why it is good practice to use HV systems on ships. But before that we need to know what is high or low in shipping industry.As per the norms in the shipping sector, any voltages above 1000 volts are considered high voltage. Slowly […]
Electrical propulsion on ships has been discussed in this article in detail. Electric propulsion is used mostly on passenger vessels or Cruise lines and other small vessels. But with emissions norms becoming stringent, they will make their way into merchant shipping as well. Electrical propulsion has lot of advantages over the internal combustion engines which […]
Learn how Impressed Current Cathodic Protection On Ship works and what is the need of putting such system. We will start with basics, and then move on to the original setup which is used on ship. Ship hull is the most severely affected part when it comes to contact with seawater. From the day ship […]
Insulation testing is an important activity when it comes to the electric equipments. To carry the current in individual conductors, they should be insulated to each other and avoiding any contact between them. It is same like you want to transport water to other place. But you use pipe for that. Pipe is a like […]
Insulated and earthed neutral system both have been explained in this article in a detailed manner. We will also discuss the merits and demerits of individual systems. For critical equipments, we often use the insulated earth neutral system on ship. But earthed system is also important. And we will learn as how earthed system works. […]
Automatic Voltage Regulator have been discussed in this article, and the component associated with it. AVR is used on the ship generators and as name suggest it is used for voltage regulation in case there is a increase or decrease in power demands suddenly. AVR can be called as the governor for the generator when […]
This page is dedicated for discussing and answering of problem related to marine electrical, electronics and controls devices and circuits, their trouble shooting. Also, the theory related to them which are essential for the electrical officer and marine engineer officer on ship. Also, students who are appearing for their exam will find this page quite […]
