here is the step by step procedure on how to run synchronous generators in parallel. #seaman #generator #engine #seafarer #reefer #refrigeration #refrigerationcycle #refrigerationequipment #airconditioner
Such a great work. Carry on. I would like to ask you to show us how to set the speed governor into doop mode ? So that the load sharing can be performed??
Hello my friend, you are making very very useful video. I learned lot things from your video. I have one request to you. Plz make one video on three lamp parelling method in details .
older detroit diesel units had 3 lamps which flashed slowly as govnor was adjusted to voltage and frequency,then as they go dark on the flash cycle you threw in the breaker
First of all, thank you very much for your information. I am working as a chief engineer on a ship. There are 4 690 volt generators on our ship. When we parallelize the generators, the generator number 3 gives load too high deviation alarm. How we can solve this problem. I would be glad if you help.
sir ask lng po ako,ano po ang problima sa isang unit namin nakung i on manually ang synchroscope ang pointer at synchronizing lamp ay steady lng at nag umiilaw naman
How does the shaft generator work? Can it only be used when the main engine (and thus the vessel) is running at a specific speed, since the engine RPM is directly related to the frequency?
Most likely the ship has a variable pitch prop so while the ME RPM needs to be constsnt, it will still work the same way ultimately and the ship can traverse at any desired speed by varying prop pitch instead of ME rotation
If it’s way out of sync, you could effectively wreck something, since the machine tries to change speed in an instant to match the others, which it can’t do. May sever a shaft or coupling or mounting bolts or worse case wreck windings. That’s a no no. The automatic as well as manual operation may have protective relays supervising the operation and if it sees a condition not to spec, will block closing of the circuit breaker.
You have some leeway, have to read the specifications, if you close the sync breaker way out, you may do severe damage. Worse than blackout. The senior operators are trained in this practice.
I changed the current transformers in generator number 3. I changed the syncronoscope. I changed the screen. I changed the cotroller. Unfortunately I couldn't find a solution. please help.
Dear i have 4 g but when i sencroniz 3 g will close one of them delay to close after one minut it will clos immediately the other 3 show revers power what will be the problem pleas explain to me
When the generator number 3 is on alone, the voltage and amperage values are normal, but when we parallelize the other generators, the amperage values in the generator number 3 increase too much and load too high deviation alarm is given.
its because on auto synchronization load vary and due to this variation of load some alarma come. it will be automatically adjusted ..... by the way good observation 👍👍
The engine of the generator or generators you want to add load to has to be given more fuel. It doesn’t run faster but takes more of the load vs. the other generators on line at the time. Looks like the control marked with the word governor motor is what does it, at least in manual. If they have an automatic system there to do it fine or do it manually as auxiliary power demands change. I presume they have synchronous generators.

Good information. Thanks for sharing
Awesome stuff that's worth learning...keep up the great work..!
very enjoyable video you are good teacher :)
Excellent work
Very good
Very awesome video.
Thank you for sharing your knowledge.
Thank you! You made it look easy.
Just completed the refit couple of months ago 😁😁😁😁. Hope you like our systems. Nice video!!!
REally love you video. Best Explanation with handson Explanation😍
Thanks for your sharing
Nice video mate, all good as standard !
Great video, thanks.
Very useful explanation
Thank you sir for sharing your knowledge, for free❤...
Thank you these is good video
Omron timers are quite troublesome i see...Thanks for the excellent videos you create for us!
Thank you Jake awesome tutorial
Thank you for watching
AWESOME !!!!...thank you
Such a great work. Carry on. I would like to ask you to show us how to set the speed governor into doop mode ? So that the load sharing can be performed??
Thanks for share
I love you my friend thanks you helped me a lot
Very smart man LeckyJake
Salamt madami. Dami ko natutunan sa channel na to
Thanks sa support
Thank you leckyjake.. hope to work with you in future👍🏼👍🏼👍🏼
Awesome, i hope you share a Video of Emergency Generator battery charging system 💝
Thank you so much sir …
Hello my friend, you are making very very useful video. I learned lot things from your video. I have one request to you. Plz make one video on three lamp parelling method in details .
Thanks!
thanks sir
basta pinoy! lakas yarn
Thank you
thank you
Do video on Magnetron change, Generator sensors (PT-100 etc.) , Generator protection and Winch faults
older detroit diesel units had 3 lamps which flashed slowly as govnor was adjusted to voltage and frequency,then as they go dark on the flash cycle you threw in the breaker
We have them lamps also on newer vessels, together with other stuff like synchroscopes and so on...
Salamat lecky Jake

Mr secretary sa plc system naman😊
And make one video. How to increase or decrease voltage by AVR.
❤
Hy Jake, How the PMS working is automatic panel ??
sir ask lng po ako,ano po ang problima sa isang unit namin nakung i on manually ang synchroscope ang pointer at synchronizing lamp ay steady lng at nag umiilaw naman
Thanks for the video…. But can I please get the circuit diagram

Hi, i have a question
What will happen if we close the breaker but the synchronisation conditions are not met
If it’s way out of sync, you could effectively wreck something, since the machine tries to change speed in an instant to match the others, which it can’t do. May sever a shaft or coupling or mounting bolts or worse case wreck windings. That’s a no no. The automatic as well as manual operation may have protective relays supervising the operation and if it sees a condition not to spec, will block closing of the circuit breaker.
Why is the voltage around 260V? Isn't that quite high? I was expecting something around 230-250V (400V 3phase).
Sir Can explain manual load sharing video ..I mean near generator
Ask lang ako sir lec my possibilty ba na mag blackout pag di ma timing ang pag synchronize?
You have some leeway, have to read the specifications, if you close the sync breaker way out, you may do severe damage. Worse than blackout. The senior operators are trained in this practice.
Apfc panel auto me pf maintain nhi ho pata hi keya karan hi
I changed the current transformers in generator number 3. I changed the syncronoscope. I changed the screen. I changed the cotroller. Unfortunately I couldn't find a solution. please help.
Panu po pag nag agawan ng load yung 2 genset, anu po dapat gawin?o anu po mostly yung problem pagganun?.Salamat

Are the “other” generators taking load once synchronized?
its because on auto synchronization load vary and due to this variation of load some alarma come. it will be automatically adjusted ..... by the way good observation 👍👍
Hi friend where are you from
Sir lecky,how to fix the mcb computer system fail in synchonized panel is alarm indication??
just refer to your wiring diagram and trace the source

Sir , can you explain how the load balancing unit work , i don't get it yet
The engine of the generator or generators you want to add load to has to be given more fuel. It doesn’t run faster but takes more of the load vs. the other generators on line at the time.

Hello sir i am fresh electrical engineer and want to go on ship kindly guide me through interview and 1st day
Bakit di sabay mag control ng load sa gen 3 at gen 4. Inisa isa nya kala ko sabay dapat pag ganun load sharing
Do you got an e mail address maybe when i need help of better understanding in the future i can contact you..
You did not even blow through the generator you started it directly?
Please sir can u give out your social media handle
