Lineman's Reference - XFMR LAB

App is far to clunky, not worth using when you can only wire up 1/3 of the banks due to the lines not connecting.

Learning a lot from this app. Only problem I’ve come across is how to tie the H1/H2 bushings to the tank ground and neutral

Your eye delta is wrong. Other than that good app.

Great app just noticed that on some of the banks you can’t bus the secondary x2 to x2 bushing for delta secondary’s. It use to work but if the developers can fix that then it would get that 5th star in my book

The app has some flaws but nothing you can’t work around. Helped me a lot on learning transformer configurations.

I really like this app, I recommend it to my apprentices to learn the concept of banking transformers. What I do no like is that I can’t select to build banks with subtractive transformers. Not every system is less than 8kv. Also, when building a bank, if the wiring on the X bushings is not to the exact phase it’s drawn on the diagrams, it won’t accept the answer.

This is a great app, let me just start with that. It would be great if you could build your own banks and check voltage and what not. The set diagrams are awesome but being able to play around with different connections would make it better. Also tap changer settings and info would also be a great addition.

If you thought you’d be able to run a lot of different scenarios with this don’t bother. The app won’t let you do a ton of stuff and if you’re trying to use it to show an apprentice or something their mistake and recreate it digitally it almost certainly won’t accurately recreate that. Basically you build it correct or it doesn’t much do anything, not much point of this unless you really just want an interactive diagram because you can’t follow one that doesn’t have movable parts—which makes zero sense to me.

Awesome app helped me get my secondary connections down but it would be even better you guys added a create your own bank option just so guys can get a better grasp. Also be helpful if you could add a wye bank that stays in series. Hope to see more options in the future.

How do you connect the h2 to the neutral everytime I tie them in I can get them to turn white but they come in upside down. How do I make them look like the picture ? I’m sure there is a way to do it but I’ve been messing with this app a few days and have yet to figure it out
