I have watched your series on paralleling transformers and very good explanation . Would you consider doing a video of paralleling transformers with different incoming (e.g., one being 138kV primary and one being 34.5kV primary and both being 13.8kV secondary). Same impedance with different ratios NLTC?

Thank you for the question. One of the conditions for paralleling transformers is to have the same voltage. Any mismatch will lead to circulating currents. Also if two different voltages are connected together, it will exceed insulation withstand of the lowest voltage. Hope this helps.

The problem with your ask is not really that the Primary Voltages are different, that is a problem yes... but the issue is going to be that you are describing two diff Primary Sources... the will be out of phase and when you connect those Secondary's... those will be out of phase as well. THAT is going to be bad....If you could phase lock the inputs, you could pull it off. But your ask is to Parallel the outputs ONLY.... So, yeah the Phase issue is very much a problem
