Description

This app is a fully functional transformer lab simulator that was designed and developed by a journeyman lineman, for lineman and apprentices. You can use this app to study and learn your transformer connections. When the fuses are closed in you can test your connections with a volt meter, ohm meter, and a rotation meter. Abnormal voltages and cutout fuses exploding can occur when improper connections are made. In the labs you can also inspect the transformers' nameplates and secondary coils. Quick reference diagrams, basic transformer informational reading material and more are available in this application. The Quiz mode lets you test your knowledge. The Company Customized Experience is a way for your Power Company to work with us where we will modify the app to match their spec. Tell them to reach out to us if they are interested! Current Labs in this app: -Single Phase- Single Bushing Topside Dual Bushing Topside -Three Phase- Delta Delta Closed Delta Wye Closed Wye Delta Closed Wye Wye Closed Delta Delta Open Wye Delta Open -Misc- Paralleling 4th Cutout Troubleshooting Tutorial -Advanced- Straight 480 240/480 277/480 Corner Grounded 240 or 480 Wye Wye 5 Wire (120/240 & 120/208) -Quiz- Test your transformer wiring knowledge by completing a predetermined assortment of labs at random. Blowing fuses and attempting to Check Work subtract from your overall score out of 100. -Advanced Quiz- Test your overall transformer knowledge by completing a series of random quizzes where you receive basic job-site information and have to choose the correct transformer nameplate and secondary coil configuration. You will then have the option to wire up the corresponding bank.

  • Almost perfect

    I’m using this app to practice my connections for my transformer class and it’s really really great well worth the 10$ but when I wire up a bank correctly it will tell me it’s wrong it only does this with the delta delta or the wye wye I will match them up perfectly with the image but still say it’s wrong I’ve even asked my teacher if they are wired correctly and he said yes. Once that gets fixed this app will be 5/5
  • Okay app

    What I did not like is you can’t get a zero read on like phases it gives a 240 read when it is really a zero read this was wye delta bank straight 240

    Some of the answers in the advance quiz need to be fixed for the transformer selection question parts of the test. Selecting the correct transformer subtracts two points while selecting the improper voltage per nameplate is shown as correct. Please fix this as it could be confusing to anyone trying to learn.
  • Fuse blows when nothings wrong

    When making a delta secondary hookup, when you attach the case grounds, the fuse blows and says it’s wrong. Not sure if it’s a bug or I’m im doing something wrong
  • Great for linemen

    Great app. Highly recommend for any apprentices or journeymen looking to brush up on their banking skills. Would love to see paralleling 3 phase banks in the future. I’ve had the app for a while and have noticed new features come up, like single phase paralleling and troubleshooting.
  • Wrong wiring in diagram

    The diagram for a 277/480 Wye/Wye bank is wrong. Also the H.V. on the transformer name plate on dual bushing transformer is wrong.
  • Shows wrong connection with right hook up

    I’ll make a connection and check work, shows right voltage but wrong connection. Check the system’s connection and it’s exactly the same. Refresh connection and it will show it as correct. Downloaded this for my apprentices but I can’t use this app and worry about confusion or frustration. Good theory, too many bugs…
  • Paralleling

    By Triwaytitan
    Great app for guys to start understanding banks! Only issue is when paralleling cans. Rather than running the x3 and x1 to the same phase it wants you to run to opposite phases. That isn’t parallel, that’s a 240 secondary flash.
  • Voltmeter doesn’t work and needs more labs!

    By Fulololol
    Cool app, but the voltmeter doesn’t work! It will not let you drop the leads to the voltmeter on the bottom two phases… this prevents you from doing the tests because in the test it tells you to check secondary voltage with the meter… Also needs more labs! It’d be great if there were just more labs with different scenarios, or a feature like “customer needs 480 3 phase power for x load, pick the right transformer and hook up” type situations.
  • Overall great app!

    I have no complaints about this app.. it has definitely helped me learn about constructing banks and it has put me buses ahead of other apprentices in my area. **One thing I do wish to see in the app is the Delta & Wye vector charts for both primary and secondary.** this would help greatly when learning how to build banks.
