Awesome this really helps me! Been looking for something like this! Also, I’m an apprentice currently trying to learn but I think there should be a hints button to try to see what your doing wrong.

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.

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

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.

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!!

Lighter bank & metering

What about a lighter bank category for closed banks or corner grounded banks? Any chance on expanding into metering? Great app, has helped me a lot.

I’m an apprentice lineman an this helped understand so much however, I would love to see the “advanced tx” you mention in above comment especially the additive an subtractive portion. Great app an very very helpful for myself.

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

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

Great app

This app is awesome to play around with to learn and review your transformers and how they are built. I’ve recommended it to several people and will continue to recommend it to new apprentices!

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. Quick reference diagrams, basic transformer informational reading material and more are available in this application.
