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!

gatelegs,
Great app, let’s take it up a notch
How about being able to select transformers from a list (a.k.a. transformer dock)so to be able to bank subtractive and additives transformers. Also, would like to be able to tie three phase secondary legs on the open secondary lines below transformers instead of tying secondary bushings then dropping one leg to secondary. Just suggestion to make people understand the beast. UPDATE! The developer has contacted me that they are already moving towards these improvements!!
mmikemmike,
Love the app but…
Definitely some issues. I’ll wire up a bank correctly and it’ll tell me it’s wrong. I can delete my secondary’s and reconnect them exactly the same way and close the fuses again and it’ll say it’s right. Also, I’ll wire up a wye delta (for example) and it’ll say “this is a correct way to wire a delta delta bank” when obviously it should say wye delta. Lastly the app needs to be run with a horizontal screen but you can’t put the volt meter on the c phase secondary leads because of the layout. Still worth the $10 with the few issues it has
nolanhiestand,
Good learning/practice tool
Good learning/practice tool! Could use some minor adjustments such as easier access to lines(too close to bottom of screen), a way to look back at the bank you are building during a quiz (without restarting) and the addition of power banks. Overall good app though
Fulololol,
Voltmeter doesn’t work and needs more labs!
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.

clancy e,
Neat idea still needs work!
Some neat information. Dislike that it doesn’t tell you what it would like you to correct just says something is wrong? Volt meter doesn’t work. I made a perfectly good connection and it kept blowing the doors?? I know this was right but assume someone didn’t know how to make the connection how are they supposed to learn from this app? It’s a neat idea but has lots of room for improvement hopefully my 10 dollar donation to what seems to be a unfinished product helps finish this app.
Djudd260,
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.
Wingshot78,
Pretty Good
This app seems to work pretty good to learn some standard transformer connections. I’d love to be able to hit a button and see the vectors for the transformers. Maybe some way to practice drawing the vectors for each bank. Then vectoring two banks to see if they could phase.
Silverx87,
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.
coreym1209,
Awesome!!!!
Been a lineman for a few years and have always struggled understanding banks but this has made it easy and fun to memorize everything about bank building! Be your brothers keeper and share this app with them
tbaker575,
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…
