Yes, sir. That does make sense. For some reason I was looking into using sequence impedances and didn't think to just do a simple nodal analysis. Thanks again for your help.

In this example, yes. Really what I'm after is getting an idea of what the percentage deviation would be on the line currents if a three-phase delta secondary comprised of single phase transformers that had different percent impedances (which in my case, two cans have 5.35%Z while the third has...

By the way, this is not a homework question. I just want to see the effects of difference in transformer impedances on the line currents, even if there are nothing but three-phase loads in the facility. VFD's and soft starts are tripping on current imbalance.

Hello everyone, I have a three phase circuit that consists of a three-phase transformer bank feeding a balanced three-phase delta load. The transformer bank consists of three single phase transformers connected in delta. Each transformer is rated at 333kVA, 2400V. Two of the transformers...
