Recently I had a blown fuse on the primary of a DYn11 high voltage transformer. The motors connected to the secondary of the transformers burnt out due to the reduced voltage. I believe that the motors did not "single Phase" in the true sense of the phrase but suffered from a reduced and unbalanced voltage on the secondary side of the transformer. Can anyone comment on what the secondary line and phase voltages would be.
