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.
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.
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.
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.
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.
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.
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.

Great 👍 job. But I have a question ❓ my question is this: this five pin relay would only start the gen but couldn't put it off, why? Pls modify it. Thanks
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.
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
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.
one question, why are you switching the neutrals? shouldn't the system share the neutral and the ground? for a simpler setup all you need is DPDT relay powered by the generator manually started/offed when the main power goes off/on and please keep the neutral and grounds bonded? thanks for posting.
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?
No, the idea is good but it does not work for commercial standard gasoline or diesel generators. The only way it works is for the generator to have the "Remote Start" option. A generator without "Remote Start" must consider a pulse for ignition and then bring the ignition coil to ground for shutdown. The ignition coil cannot be kept energized because the starter motor will burn out. And if the ignition coil is not grounded, the generator will only stop due to lack of fuel. I don't know of any generator for home use with the Remote Start option.
This is a nice video tutorial for those electricians who doesn’t know much about this one like me uhm brother is it an automatic type of switch? When the main supply is off then the generator will it start automatically?? Thanks bro 👍👍
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 😮
You need a 2 wire gen controller, it start and stop the engine with his delay ( for warming up prior Engaged to load house and cooling down prior shooting down the engine, and if gen is a gas engine it also control the choke
This [on the link] is better, I guess. The Generator starts and stops by itself depending on mains power supply. th-cam.com/video/BRf1j4KcWow/w-d-xo.html EDIT ============== The corrected explained video.. th-cam.com/video/rHpZEmuHknQ/w-d-xo.html
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.
Please help me out. I bought "KOZUKA SINGLE PHASE 60A DIGITAL KWH METER DDS3666" and electricians installed it under my air conditioning, but wiring is not the same with this video. They put line/brown wire together on the left side and neutral/blue wire together on the right side. It works, but is it correct?
Hi Thanks for the details, but my Generator haven't AMF , SO can you pls show diagram how relay to be contact to Generator? and if possible AMF diagram.
There is one little thing with this.Correct me if I am wrong. It seems that the generator starter will keep on turning that starter motor constantly until the grid voltage get back.
the generator starter relay should have a timer to avoid burning out the starter on the generator and also delay timer on the main power contactor to wait power to stabilize to avoid generator to turn on off when the mains power not stable
There not connected when one is closed the other is open on the live and Netrual This method is Double pole so it switches on and off and keep the netrual and lives from the sources apart. This is good safe practice..still.needs interlock..
Diagram is ok. But I have simple comments. 1. Is it advisable if normal power is "Off" the normally closed relay contact always triggering the starter generator? 2. What if the normal power is back to online, the generator will automatically to "Off"?
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.
@@slengineeringacademy2234 hola que tal, me llamo juan soy de Argentina, soy estudiante en electricidad industrial, el video esta muy bueno, lastima que esta en ingles, queria hacerte un par de preguntas sobre el video, ¿En que parte del generador van conectado el relay que va arriba del generador y del interruptor termo magnetico?

The starter will continuously run and the genset wont switch of if you break power to the starter you need to have extra pole to actuate cutout en delay on timer to controll the relay when swithing on and delay off relay to trip the cutout
Very nice. Do we have a layout with 3 phase 380v gen. for household use with mechanical interlock. All today ATS boards have installed an ATM (automatic control module) that regulate the time for the start and the preheat and other functions (output current,Amp, etc )
Would have been much more informative if as each step occurred you showed the effect of the relay being de-energized and the contacts closing / opening with the flow of electricity changing paths. Or, at least a voice over. All the work to put this together just came up short of being really effective.
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

If the generator does not have an AVR (Automatic Voltage Regulator) I would incorporate a Delay Timer.

There is capacitor controlled voltage regulation. But still whould put a delay in so the generator doesn’t start immediately.
you can buil AVR TO Control the exciter and the speed of the Alternator okay
You show us step by step and even the connection inside the contactor. you do great, clearly understandable very specific its so nice

How can mechanical interlock be achieved
@@augustinechika3881 Mechanical interlocks are available from the power contactor suppliers.

Exactly! For additional safety.. good point
Yes must use interlock magnetic contactor, I'll always use this when I'm doing auto generator
You are correct but you need to add one more contactor and replay delay timer to the supply to d b
Thanks you.❤👍
Bro you could post share a picture for the connection please??

great learning but im thinking about the two circuit breaker w/c is at ON position there might be some safety issue. please enlighten.

Merci beaucoup pour cette prestation,on attend d'autre avec plus de source de courant si c'est possible.
2 time relays should be installed in this system to prevent the phases from colliding.thank you.

There is one little thing with this.Correct me if I am wrong. It seems that the generator starter will keep on turning that starter motor constantly until the grid voltage get back.
Great 👌 work ❤
the generator starter relay should have a timer to avoid burning out the starter on the generator and also delay timer on the main power contactor to wait power to stabilize to avoid generator to turn on off when the mains power not stable
Great idea
100% needs a timer on the relay or a sea set controller thag looks for an increase in voltage so dont attempt a 2n or 3rd try to start.
Why do you have to combined neutral line to phases?? That's the area i failed to understand, if you can explain it pls, otherwise appreciated
There not connected when one is closed the other is open on the live and Netrual
This method is Double pole so it switches on and off and keep the netrual and lives from the sources apart.
This is good safe practice..still.needs interlock..
WHICH SOFTWARE YOU USE TO ANIMATE YOUR LESSONS
Diagram is ok. But I have simple comments.
1. Is it advisable if normal power is "Off" the normally closed relay contact always triggering the starter generator?
2. What if the normal power is back to online, the generator will automatically to "Off"?
Thank you for the well explained illustration
Very nice demo
Super explain👌👌👌👌👌👌
Very informative presentation.please let me know the software/apps you used in your presentation.
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.
Well explained thank you.What if its a solar and you dont have that generator stator connection?Yet you want to work the same
Thanks for watching and your significant comment..👍
Yes it work on solar too. But it need AC supply

Will work on a solar inverter that works on island mode..basically an inverter that is happy without a grid..
good illustration for automatic start electric
Hello nice 1,,,what amperes are your contactors,,,
The starter will continuously run and the genset wont switch of if you break power to the starter you need to have extra pole to actuate cutout en delay on timer to controll the relay when swithing on and delay off relay to trip the cutout
Appreciate the nice work done
Very nice. Do we have a layout with 3 phase 380v gen. for household use with mechanical interlock. All today ATS boards have installed an ATM (automatic control module) that regulate the time for the start and the preheat and other functions (output current,Amp, etc )
Just copy the above and make it 4 pole
L1
L2
L3
N
So basically copy above but have a 4 pole relay interlocked (expensive thou)
Great video. BUT Was it necessary to use a relay, can it work without the relay ? Why the relay
Need relay to tell genny to start but the diahram needs to add a timmer relay or you couod burn out the genny starter..
Can I know what apps/software you used in white board animation. Thanks in advance.
I use two 12V relays, and another in the inverter. 12V DC regulator introduces a delay in switching.
Huh?

Both contactors are same or not?
Symbol changed in circuit drawing.
Both are same.
Yes, both are the same as long as the load is the same.
Best channel
Thank you.❤👍
Good explanation but generator starter wont stop running how do you fix that
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.
