In this blog post, we will discuss what happens when two generators are running in parallel and one of them loses excitation. Excitation is the process of providing a magnetic field to the rotor of a synchronous generator, which enables it to produce electrical power. When a generator loses excitation, it can no longer supply […]
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 […]
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. […]
Generator Protection Devices have been discussed in this article and they are as follows: ● Over Current Inverse Time Relay OCIR ● Over Current Instantaneous ● Negative Phase Sequence NPS ● Current Differential ● Earth Leakage Relay ● Under And Over Frequency ● Lock Out Trip ● Reverse Power Trip ● Over or Under Voltage […]
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 […]
Confused about the HV STCW Course. Well learn about it here like who need to do HV course, duration of the course and fees structure as well. Colleges offering high voltage course are also discussed in this post. Let’s learn about this newly added HV voltage course for the seafarers as per the STCW manila amendments. What is this STCW High Voltage […]
Oil Mist Detector is equipment which monitors the environment inside a crankcase space of an internal combustion engine and thus tells the engineer, in case of formation of any type of explosive vapors occurring in the crankcase of engine. This is a preventive step avoiding crankcase explosion taking place. Here is the step by step procedure, to be followed in […]
