- An #automatic_transfer_switch (#ATS) or an #automatic_changeover_switch transfers power supply from its primary source to a backup #generator automatically, when it senses partly failure or a total failure in the primary source.
When a failure occurs in the primary power system the ATS invokes the backup source which is a three phase diesel powered #automatic_generator here, to run electric equipment until utility power is restored.
This ATS is capable of automatic starting and stopping of the generator too, in addition to the automatic transferring of power to the load.
ATS needs to be properly designed and wired to the primary and backup power sources, as it must communicate effectively with both power sources to switch power and connect the equipment to the proper power source with a minimum delay period.

Sir, You are the great teacher for electrician. May Allah bless you. Thanks.
Thank you
A well explained information supported with clear pictorial diagram. Thank you for dedicating your time and effort to share your knowledge on this particular topic. Thank you...much appreciated
Thank you.
Very good.thank you sir
Thank you.
very good video sir thanks
Thank You.
Very interesting & really appreciated
Thank you
Is this diagram can be in actual wiring of the ats panel?
Yes. Basic arrangement is this.
Changes are there according to the different models and brands.
Very clear and understanding
Thank you
great lectures credible and amazing. any chance of scholarships on electrical and electronic engineering into your reputable and renowned Electro Academy..
We currently teach only through TH-cam media.
We may consider this when we start our learning center soon.
The best tutorial..
Thank you 👍
Thanks for the lessons, please can I apply this to a single Phase? And can I have the circuit diagram for this video, thanks
Yes, you can.
Thanks for the video, but please can I see its physical build-up
Thank you.
Standard arrangement is shown here with current flow animation, mainly for the ones who need to understand the automatic starting of the generator easily.
Please if am to design this ATS for a load wattage of 25,000watts in facility what is the the size of panel by millimeters I should request to buy? That would contain these components
Actually the size of the panel is to be decided according to the component sizes and the relevant wiring work too. Some component sizes might be different according to their brands also.
If you are not an Electrician, better to get help from one to get good idea on sizing of the panel board.
Can you explain how connect swich of generator to run and stop generator auto. Please draw wiring diagram for connections
yes I would like to see the same
Generator manual start button wires need to be connected to the two green points marked as start connection on the diagram for automatic starting.
Generator stop button wires need to be connected to the two red dots marked as stop connection for auto stopping of the generator.
If you need an auto - manual switch for generator, connection from the battery can be provided through a 2 pole breaker.
This breaker OFF position will act as generator on manual starting only, still the power will automatically change over after you start the generator manually.
@@ElectroAcademyEA
I didn't understand you can you draw wiring diagram to explain that
Thank you ❣️❣️❣️
Excellent explanation! Just one question though: contactors have 3 main poles and 2 accessory poles?? The ones I usually see have just one accessory...
Normally contactors have 2 auxiliary contact points, NO and NC.
But, according to the requirement, you can purchase heavy duty contactors with 4 auxiliary contact points, two NO and two NC points.
There are contactors where you can add more auxiliary contact points on to it also.
Additional contact points can be slide on to the contactor top and lock it.
It should be done according to the manufacturer recommendations only.
@@ElectroAcademyEA good please should I use stop push and start push buttons to manually switch off and on generator?
@@michaelisongekwere1402 Yes.
Further, you can use a 2 pole breaker when wiring 12 volt power from the battery to this system.
Breaker "ON" position is your generator automatic start/stop operating position.
Similarly, breaker "OFF" position will act as generator manual start/stop position.
In both these positions power transferring will be fully automatic, although you have to start the generator manually, in breaker "OFF" position.
❤❤
Thank you
On the grid side you used two timer relays
Can’t one timer relay do the job
Timer 1 is there to make generator to run on load for 2 to 3 minutes even after grid power is available.
If grid power goes off again within this period, generator is on load and power supply will not be interupted.
Although recommended, you can omit this timer if intermittent power disturbances are minimal.
Too difficult to follow . Need to slow down a bit !
Thanks for your comment
Any Whatsapp group pls I want to join
I have been looking for these , too long.
Thank you
Thanks for the lessons, please can I apply this to a single Phase? And can I have the circuit diagram for this video, thanks
Thanks in anticipation
Thank you.
You can use this for single phase generator wiring too.
Instead of 3 phase 3 wires on power side of two contactors, use live wire and neutral wire on L1 and L3 terminals.
Keep L2 terminal empty.
Control wiring is the same as shown in this video.
شكرا لك أخي الكريم على هذا الفيديو المهم استمر بالعطاء
يا حبذا لو تعمل لنا فيديو اخر عن كيفيه اداره ATS ثلاث مراحل كهرباء الدولة الحكومية وكذالك كهرباء الاشتراك في الحارة وكهرباء مولد البيت في الداخل كيف الىبط بينهما
شكرًا لك
Sir can you provide schematic diagram for this system
Thanks sir, please can i see how the start and stop connection is done physically, with stop and start button.
I will be grateful if granted.
Thanks
Please try the video on below link.
th-cam.com/video/_6WhieL50GI/w-d-xo.html&feature=share9
This was an explanation thank you Sir please what are components that make up this design and connection? I know 2 magnetic contactor, 1 phase failure relay, 3 Double pole double throw 8 relay, 2 AC double pole breaker, 5 Timers
Secondly on the battery relays you connected port 1 and 3 of start and port 1 and 3 of stop to what components is it 1 and 2 start- push and 3 and 4 stop-push components?
Yes.
Dear All,
DPDT relay means Double Pole Double Throw Relay.
Double pole is mispronounced here as Double port @ 1:32.
Kindly take a note on this, when viewing/listening to the video.
Regards,
EA.
The start connection is the one from AUTOMATIC button on generator screen?how to connect it on that relay?thank u
Best way is to check with the generator supplier.
Then its easy with relative brands.
all ok.
When my grid off then 3 hours Later generator start.
How to set the time
Hope you can get help from an electrician to correct this fault.
Necessary timer settings are described in the video.
Please sir, the relays and timers for the gen auto start are they DC or AC?
Battery connected relays and timers are DC.
All others are AC.
Hey sir what type of timer relay used. Is all the timer relay ON DELAY?
All the timer relays used here are ON DELAY type.
Actually we can use ON DELAY timer relays for average OFF DELAY functions also, by using NO and NC contacts properly.
Ok thank you. I'm going to build a system exactly like this soon for backup system
Is there any other way I can get in contact with you to get some more information about the parts to be purchased?
This is very clear, thanks
Thank you
Very helpful thanks man
Thank you
Hello, where do we get the neutral for the load from? How do we ensure there is always a neutral cable from both supplies without them interconnecting?
From the generator supply, you get separate neutral cable.
So, the two neutral cables need to be connected separately, as shown on the video.
@@ElectroAcademyEA It only shows the 3 active wires going to the load, how does the neutral wire connect to the load?
Sorry for that I have not shown it in the video.
As done for the 3 power lines, you need to get two neutral lines separately from the grid and from the generator to the junction box, and connect it.
From the junction box, only one neutral line to the load.
3 pole contactors on grid side and generator side, need to be changed with 4 pole contactors to provide neutral wire through it.
@@ElectroAcademyEA 4 pole contactor! okay thank you very much
That was helpful.
Thank you

OK but I have a question how would this design change if you you wanted to build an ATS that changes between 3 sources. An example would be if you had grid, solar backup and generator in that priority order. Would be great to know as there's almost no info available on this specific topic
Bro, it’s simple, just make another same set of panel and it’s out considered as second prior after the grid, for example just do this circuit with solar and generator and it’s out again do with grid supply, in this way you can make infinite number of power sources 💪😉
nice
Thank you
Thank you sir
Thank you
thanks sir,thank you so much
Thank you.
Thanks for made the video🌹
Thank you.
Are you doing relay switch for video
After that how does the generator start if the grid is out.
Through battery power
And what? Meaning the the battery have to be charge right?
Yes. You need to have a battery charger (powered by grid side) to keep the battery fully charged, in order to start the generator during a power outage.
make the video two pump controlled by latching relay plz
Thanks sir
Thank you
Que buen tutorial ... Lo malo es que no se hablar ingles 🤦♂️...

Very nice and vivid current flow is illustrated. Makes everything clear how does it work. And explained simple. Much of thanks to u !
Thank you👍
@@ElectroAcademyEA waiting for more videos like that. if u can make industrial machines
I love you 😘 great work and very helpful diagram video sooo thanks.............
Thank you
I am very thankful to you Sir for this very informative video you have shared with those of us who are in a real need for knowledge of ATS control phenomenon. I love the video. Much thanks and great appreciation. Cheers
Thank you
Pl show timer s T1 T2 in video with colour animation. Thanks again for video,👌👌👌👌👌
Thank you
Can we common all the neutral...??
No.
Grid and generator side neutral lines need to be kept separated, to enable safety features like RCDs to work correctly.
So excellent video about automation..
Thanks for like this video from Bangladesh
Thank you
Thank you Sir. You effort is much appreciated.
Best ATS video ever
Thank you
Sir you where my teacher you are the best 👍🔥
Thank you
This design is suitable for Single Phase Gride and Single Phase Generator?
and how many self start attempt?
Yes. You can use it on single phase grid with single phase generator.
Normally, generator should start with one start attempt.
If there are dificulties with starting, we need to check and correct it first.
Well done sir, pls how will one connect the ats for single phase generator to auto start/stop
For single phase generator, same two magnetic contactors can be used.
Instead of three phase lines, live wire and the neutral wire can be taken through it. One terminal on both contactors will be empty.
wow nice very very usefull video thank you
Thank you
10q so much for taking time do this lecture and took time to upload it
Thank you
Very clear and understanding,thanks for this information
Thank you
you are a teacher with teaching qualities I keep to your videos.
Thank you
what a wonderful explanation it was . thanks a lot to the channel
Thank you
Thank you so much, sir! A very good quality video! Much appreciated!
Thank you
Thank you
your sub-title covers the timer socket wiring configuration, it's bad video.
You can stop subtitles by clicking the "CC" icon on the screen.
Very Nice . Can we have a ladder diagram of the ATS explained above?
Thank you.
Will try to do when time permits
Great Sir, Do you have 3 power source ATS model
Generally, control circuit needs only a single phase supply or direct current supplied through a battery, to operate magnetic contactors.
great work ,which software have you used
For animation work, Microsoft power point.
Thank you.
sir please make next video on latching relay plz.
Ok. When the time permits.
Insightful and educative ❤
Thank you
Please explain how Manual and Auto mode is achieved in ATS
Introduce a two pole Isolator or a breaker and take battery wires to the auto start and stop connections through it.
Isolator "ON" position will act as "AUTO" mode.
Isolator "OFF" position will be the "MANUAL" position.
When Isolator is at OFF position, you need to start the generator manually when grid power is not there.
It will supply power to the contactor top and generator side control line breaker, allowing power to transfer automatically to the load.
@@ElectroAcademyEA thanks for your prompt response
How to emergence stop button. Sir..
Emergency stop button should come with the generator itself.
Very good, thanks.
Thank you
Good.. nice thank you
Thank you
Thanks a lot
It's very useful 👍💕
