This app is a fully functional transformer lab simulator that was designed and developed by 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 scenes and more are present in this application.

*Note at this time there are known bugs with certain apple products but on these devices the app functions to a usable degree. Ongoing development and bug fixes are being worked on as they are reported.*
