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!

Ratings and reviews

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.
