- This video explains the concept behind Synchronizing of Alternators or often also termed #paralelling of Generators. It deals with the conditions required for Paralleling with some graphical representations for easy understanding. It also explains the consequences of mistakes.
Why should you synchronize at 11 O Clock Position.

The way you explained this critical topic, neither any manual, nor any other videos has shown like this, I really appreciate your deep thinking and the way of explaining by making out of box working diagrams. I think when you were working on ships, your juniors does't needed any books for clearing there exams, hope I had worked under you. Great Sir. Thanks.
Great sir
Dear sir I couldn't find even a single video or article on internet which is nearly good as yours. Your video brought the whole idea of synchronization in to my eyes. Literally no words to explain how good is your videos are. Please keep up the good work.😍😍😍😍😍😍
Always helpful. 🙌🙌
Thanks Chief! Great job!
Great job Sir,please continue the good works
Hello Ramesh, I would like to emphasize the importance of Your tutorial videos that help a lot to many engineers around the world. When N2 is started then its speed and the frequency of the EMF produced ( it is not connected to the grid yet) is higher than the ones of the running generator on load, thus the frequencies are different and we cannot synchronize N2 with the grid at random moment. The voltage of the grid and N2 are the same before the synchronization. Controlled by AVR-s of the generators.N2 frequency is higher thus we reduce it by the potentiometer on the MSB or synchronizing panel and once the frequencies of the grid and the incoming N2 match we close the circuit breaker. 11 clock closing moment is fully correct when the potentiometer arrow is rotating clockwise(towards 12 and not towards 10). If the frequency of the incoming alternator is low compared to the bus-bars or existing alternator then the rotation is in the anti-clockwise direction.If the frequency of the incoming alternator is more, then the rotation is in the clockwise direction.
Thanks for elaborating.such comments are very useful for better understanding and thats why I keep advising the guys to go thru the comments. 🙏
@@rmetcvideos I want to express my admiration with the person who shares a lot of one's knowledge. I am from Europe and I do not see so many initiatives here in Europe from the people willing to share any knowledge, especially in regarding with the maritime industry. I am very ddelighted by Indians showing so many efforts to spread the knowledge generally and in TH-cam in particular. I am looking forward to seeing many great videos of Yours in the time to come.
Brilliant job , hats off.
So helpful chief....
Thank you sir. Please continue making such video
Very well explained sir very helpful for me
Nice one
Thank you chief ❤️
thankyou chief...
Thank you chief for shearing your experience and taking the time making this videos.
Very practical.
No one can explain better than you sir.
Thanks and welcome.Pls do share the videos amongst your friends
thankyou!
Very nicely explained Sir. Engine room and related machinery is so vast that keeping short videos could compromise explanation.Your content is very well prepared,detailed but simple, keep posting such videos we really dont mind longer videos. Please cover more electrical topics since many seafafers lack awareness in electrical and controls
Sure.. Thanks... In this era of instant Noodles very few people like you have the patience to see Long Videos :-) :-)
Very good explanation sir
Thanks and welcome.Pls do share the videos amongst your frineds
Thankyou cheif
Thnks
Thank you sir.💗
Always welcome
Thank you sir .
Requesting for making video on governor droop setting if possible .
👏
Thanks. will surely do.
Will surely do. In the pipeline. Pls do share the videos
Sir please make a video on governor droop
Can you explain about backlash in gear box , how it is measured. What are the consequences, if backlash is more.
Thank you sir, can you make video on electrical supply from shore to ship?
yes sir please make
Sir I've a doubt, when both the frequency and voltage of running and incoming generators are same then why we have to increase the frequency of incoming generator? Can't we get them in phase by waiting some time without increasing frequency of incoming generator? Please reply sir
Thanks
we are increasing the frequency a little bit in order to bring it in phase, but why the frequency remains constant as we close the acb, wont it still be little bit ahead of the bus bar ?
can we do the same by reducing the frequency a little, I meant to bring it in phase ?
No..we say they are electrically Locked... Frequency is determined by RPM ..which again controls Voltage produced and two machines connected to the same BUs cannot have different voltages....Can you have pressures on two pipes joining at the same line different???
@@rmetcvideos thank u sir, well understood
Sir can you explain about propeller jump out and propeller push up?
I thought the push up video explains that. Any specific doubt, pls do feel free to revert
Hi Sir, Why 1 Air Circuit Breaker on one side and other 2 Air Circuit Breakers on other side in main switchboard ?
Reduces risk in case of Switchboard Fire etc.AT;least Half switchboard can be in use for operating the ship
Sir. Hindi me
wapas poora record karna padega...
@@rmetcvideossir Kar dijiye record hindi mei please
