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.

@ElectroAcademyEA 2 года назад

Yes.

@renebangura8138 Год назад

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

@JOSE-tt8tb 7 месяцев назад

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 💪😉

@ibekwechidithompson4853 Год назад

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

@ElectroAcademyEA Год назад

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.

This design is suitable for Single Phase Gride and Single Phase Generator? and how many self start attempt?

@ElectroAcademyEA 2 года назад

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.

@marounabimoussa4374 2 года назад

Excellent explanation! Just one question though: contactors have 3 main poles and 2 accessory poles?? The ones I usually see have just one accessory...

@ElectroAcademyEA 2 года назад

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.

@michaelisongekwere1402 2 года назад

@@ElectroAcademyEA good please should I use stop push and start push buttons to manually switch off and on generator?

@ElectroAcademyEA 2 года назад

@@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.

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

@ElectroAcademyEA 2 года назад

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.

@irshadumerfarooq7901 Год назад

Great Sir, Do you have 3 power source ATS model

@ElectroAcademyEA Год назад

Generally, control circuit needs only a single phase supply or direct current supplied through a battery, to operate magnetic contactors.

@adammangal8530 11 месяцев назад

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?

@ElectroAcademyEA 11 месяцев назад

From the generator supply, you get separate neutral cable. So, the two neutral cables need to be connected separately, as shown on the video.

@adammangal8530 11 месяцев назад

@@ElectroAcademyEA It only shows the 3 active wires going to the load, how does the neutral wire connect to the load?

@ElectroAcademyEA 11 месяцев назад

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.

@adamsoladipupo3390 Год назад

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.

@sahanshrestha738 2 года назад

Please explain how Manual and Auto mode is achieved in ATS

@ElectroAcademyEA 2 года назад

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.

Can you explain how connect swich of generator to run and stop generator auto. Please draw wiring diagram for connections

@earthenergyhex 2 года назад

@ElectroAcademyEA 2 года назад

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 Год назад

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.

@enochyamoah7239 Год назад

On the grid side you used two timer relays Can’t one timer relay do the job

@ElectroAcademyEA Год назад

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.
