About this app

This isn't just an app with diagrams and information to read, this is a fully interactive transformer lab that can fit in your pocket. Whether you are brand new to the trade, just learning about Transformers, or a seasoned Lineman, this app can help you learn more about transformers. From transformer banks, to basic transformer troubleshooting and even basic transformer paralleling, you can learn a ton with this app.
In this app there is a functioning volt meter, ohm meter, and even rotation meter.
On the slide-out menu you can see your voltages as you make changes to the banks in live-time.
Pop the lid to transformers and view the secondary windings and blowing fuses under certain conditions are just a few of the many amazing features!
Build a custom quiz for you and your apprentices!

Love this app, one thing I would suggest is maybe a tap feature for the meter leads. Maybe like tap the lead to select it & then tap where you want it placed. It would just make it easier than dragging it across the screen.

This is how I originally had the app when I was first designing it, it seemed to create more problems than it solved, as you couldn't really see where you were selecting until it was too late. Thanks for the review!

Great app. Wish we had one setting to wire up our own banks for practice. More control over our parallel and series in the coils. Maybe add a vectoring area to check your work and learn your vectors.

Thanks for the review! I do plan on adding both vectors and a "sandbox" mode in the future, but these are both very time-consuming features.

If you can't run your x3 bushing from a phase down to where x1 bushing of c phase is without blowing a fuse, it makes it more confusing than what it needs to be. There's no difference in a buss or separate wires going to the same phase. Refund.

Thanks for the review. I had never wired transformers like this before. I've had multiple people bring this up and this will be in the next update. Contact Google for a refund.
