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

I’m using this app to practice my connections for my transformer class and it’s really really great well worth the 10$ but when I wire up a bank correctly it will tell me it’s wrong it only does this with the delta delta or the wye wye I will match them up perfectly with the image but still say it’s wrong I’ve even asked my teacher if they are wired correctly and he said yes. Once that gets fixed this app will be 5/5

What I did not like is you can’t get a zero read on like phases it gives a 240 read when it is really a zero read this was wye delta bank straight 240

Some of the answers in the advance quiz need to be fixed for the transformer selection question parts of the test. Selecting the correct transformer subtracts two points while selecting the improper voltage per nameplate is shown as correct. Please fix this as it could be confusing to anyone trying to learn.

When making a delta secondary hookup, when you attach the case grounds, the fuse blows and says it’s wrong. Not sure if it’s a bug or I’m im doing something wrong

Great app. Highly recommend for any apprentices or journeymen looking to brush up on their banking skills. Would love to see paralleling 3 phase banks in the future. I’ve had the app for a while and have noticed new features come up, like single phase paralleling and troubleshooting.

The diagram for a 277/480 Wye/Wye bank is wrong. Also the H.V. on the transformer name plate on dual bushing transformer is wrong.

I’ll make a connection and check work, shows right voltage but wrong connection. Check the system’s connection and it’s exactly the same. Refresh connection and it will show it as correct. Downloaded this for my apprentices but I can’t use this app and worry about confusion or frustration. Good theory, too many bugs…

Great app for guys to start understanding banks! Only issue is when paralleling cans. Rather than running the x3 and x1 to the same phase it wants you to run to opposite phases. That isn’t parallel, that’s a 240 secondary flash.

Cool app, but the voltmeter doesn’t work! It will not let you drop the leads to the voltmeter on the bottom two phases… this prevents you from doing the tests because in the test it tells you to check secondary voltage with the meter… Also needs more labs! It’d be great if there were just more labs with different scenarios, or a feature like “customer needs 480 3 phase power for x load, pick the right transformer and hook up” type situations.
