Automatic Changeover Switch for Generator / Automatic Transfer Switch / ATS (With Circuit Diagram)

In this video, I have explained about the fully automatic transfer switch (ATS) for single phase system.
A transfer switch (ATS) is an electrical switch that switches a load between two sources. An Automatic Transfer Switch is often installed where a backup generator is located, so that the generator may provide temporary electrical power if the utility source fails.
When utility power is interrupted, the automatic transfer switch immediately senses the problem and signals the generator to start. Afterward, it detects when the utility power is returned, the automatic transfer switch retransfer to the utility power and turn off the generator.
If you have any questions about the Automatic changeover switch, please comment below the video. I will answer your questions.

If the generator does not have an AVR (Automatic Voltage Regulator) I would incorporate a Delay Timer. Thank you for the well explained illustration 👏

[@mickuljatheseagull]

tell me an AC generator without an AVR? And the point of a delay timer to take the place of an AVR? Any AC generator without regulation will suffer high unregulated voltage.

[@jjr897]

@@mickuljatheseagull t There is capacitor controlled voltage regulation. But still whould put a delay in so the generator doesn’t start immediately.

[@007floppyboy]

You have electrical interlock between contactors, that is good. I would also have mechanical interlock between the contactors. Better still is have a set of N/O and N/C contacts on the contactor. Then its very simple to do change over.

I think is better to install a timer switch 3Second at least [ delay ON ] this timer will control a Utility magnet contactor and relay to avoid interaction between generator and utility power.

should be installed ON DELAY/Timer on the genarator contactor so that the AVR of the genarator will not damage immediately

[@LOF-ile]

They use interlocks.

[@briankinder9292]

Takes me back to 1985 when I introduced auto shore/generator change-over on our marine switch panels. Live back then was far simpler with regs, two pole 30 amp 240 VAC relay with coil wired to gen contacts. Start gen, when voltage came up it would close contacts and select gen, stop gen it returns to mains supply. Or you could wire to select mains if mains became available, otherwise gen supply was available. Like the graphics. Brian

[@AzeriZuriA]

I think the idea would be better if u change the single generator for another power source already regulated with more stable current. This way this prtotype should be working well.

[@poonamdevi4135]

Very nice sir

[@slengineeringacademy2234]

Thank you.❤👍

[@klimatbgt]

Generators nowadays have their own Auto Transfer Switch (ATS) installed in every unit if so required by the owner but its a must to have it so the load change over will take smoothly, easy with the convenience of the people in the building and the maintenance crew for their operation.

The first time you have a chance at the top is the second one I just got to go in and do the second and third and I don’t have a lot to say but I’m going in to get a little more info about it so if I can 😮

[@amm9613]

Lots of time delay comments which I agree with but the elephant in the room is the 5 pin relay, if that failed the gen will start , collide with utility and then you’re going to need a new one. Great concept, just needs fine tuned.

[@thekingwc]

It’s weird setup. Seems flawed. I would hook up power companies contractor directly to its own coil instead and leave everything else the same. When power fails generator contractor will be allowed to close. As long as power company supplies power generator contractor can’t close, whether generator is on or off.

[@thekingwc]

Wait, it seems that they both can’t close at the same time. What I don’t like is, it doesn’t automatically transfer back to power grid when power comes back. My way is better.

[@thekingwc]

So, it just hit me that when power company comes back on the signal to the relay stops and the generator turns off. It will automatically transfer back to power company. There’s nothing wrong with this setup.

[@paulmoffat9306]

Far simpler is to use a DPDT relay feeding the desired load, with the coil driven by the generator. Generator not running, power delivered to load through NC contacts, generator delivers through NO contacts (Load is on COM contacts). Fully automatic and completely isolated and functions on generator start/run only.

[@MP-wy8ir]

Absolutely right, but the DPDT just work for the 1ph case

Si es importante el retardo para el contactor del generador. Se requiere darle unos 10 segundos al menos para que logre su máxima capacidad o potencia

depende del generador y de la gama del mismo, además de su costo... Para uno económico si debería agregarse.

Do you mean an on-delay to make sure when the power comes back it turns off the generator and then this timer ⏲ counts let’s say 2 seconds to turn on the contractor from the energy company?

Hi Can you Make video for operating 2 motors alternatively using remote start stop.

[@WPg.]

Good but there is to be corrected: we must normally turn off the power supply to the starter after starting the generator group either by a speed detector

[@kasimusman895]

Good luck

[@jameskol48]

Do not make an ATS without mechanical interlock and timer. Once the utility power fails the generator start signal to be given after a time delay. Mechanical interlock to be provided between the power contactor , we cannot rely on electrical interlock, its dangerous.

[@augustinechika3881]
