Circuit Breaker Simulator

[evan003]

Does any have or use a CB simulator during functional relay testing? Haven't had much luck looking else wear online. If you do, can you provide any details you have?

Thank you

How complicated is the functional testing you are working on? For a single breaker operation, using a latching ice-cube relay may be all you would need to prove your logic. Sit down with the schematics for what you are testing and come up with a game plan. Find a relay with operate coils that will match your control voltage and the required number of NO & NC contacts. You can make this as simple or complicated as you like. If you do a lot of this type testing, make it durable and repeatable. The main thing is have fun and learn from the experience. I have been involved with end-to-end functional testing that required a PLC to simulate all the crap going on during a fault. Pulled a lot of hair out, put learned a lot about the systems!

We have been using SEL-2411's as breaker simulators. I also have a schematic for a home built one we use at Hands on Relay School if you would be interested in that. Let me know and I can get you the 2411 settings file.

Thanks,
Greg

The companies that rent CB test equipment use CB simulators regularly. They are necessary to re-test the equipment at every rental.

One such simulator was made by Doble many years ago, but I understand that it is no longer available.

The Canadian company Zensol makes them now, but they are not cheap.

You can also simply buy an old breaker that is still functional and use that instead of a simulator. You will be limited to the specific characteristics of that one breaker.

Hope this helps.

I use them for functional testing, a spare microprocessor relay can be programmed for one or you can use aux relays.

We are using circuit breaker simulator for our relay training program, not used for test and commissioning yet.
I developed cbs with plc at last year. Now, i start to rebuild it. I added auto reclose function and increased output voltage 24dc to 110v dc.

Hey Greg, if you can do you think you can send me those 2411 settings? I'm currently trying to implement a simulator using a 2440 and anything would help email eduardoj.aicrag@gmail.com

I would love to see that 2411 settings file!

yes, many utilities request use of simulator to minimize breaker operations
i have used an old 86/lockout relay, or a S&D latching relay, there are a couple to can buy but are expensive, i.e. The Barrington Model CBS (Circuit Breaker Simulator) was designed to be a convenient, lightweight alternative to operating high-voltage circuit breakers while testing the operation of substation protection relays.

Hello all, I am a Relay apprentice and am interested in scheme and settings for breaker simulator thanks in advance.

If you want to give me your email I can send you the 2411 settings along with a schematic and logic diagram.

Love to get a copy of your 2411 simulator file. I have one and never seem to have the time to develop it. I would like so see a guideline to get started. Thanks

Please share your information. Bill_leveaux@msn.com

I know this is an old thread, but just in case someone else was looking for a breaker simulator.
We use the ABB 200S series Breaker Simulator.
These are the part numbers:
200S4003 48 VDC nominal
200S4004 125 VDC nominal
200S4009 24 VDC nominal

I tried Googling them and nothing comes up. I don't know it they stopped making them or they just don't advertise them.
I am going to attach the IL (manual) for it to see if it is fitting for your usage.
501

The last time we purchased one (I think 2017) it was $800 or $900

Hi, I would love to see the schematic and the settings file. I dont have any 2411s but I have a 2440 I would like to turn into a CB simulator. Please share if you can. Thank you! Ben Smith

Hi Eduardo,
I have a spare 2440 and would like to do the same. Can you share any resources you might have? Thanks.

If you still have it can I please also get the schematic and logic diagram. Clarence.Smith@oncor.com Thank you!

I just built something very similar with an Asea (ABB) latching relay. $180 is a little pricy IMO, but maybe you can get a deal.

The last time we purchased one (I think 2017) it was $800 or $900

This should work on most SEL relays, just transpose the name of the logic points, example old SEL 321 didn't have SELogic, or it was less refined. They have WXWZ as sel variables, where now these are called SV1, SV2, etc.

Thank you

many people use them in today's test world, make your own using a LO relay or a S/D latching relay
most places don't want you pounding the breaker, verify breaker operates then insert simulator for the rest of testing or if you need to test circuit before breaker is available
