Hello All, just writing to get some input from others. I have a 75kVA 3 phase transformer and it is pretty loud. I looked to make sure the that the shipping bolts were out, that it was on rubber mounts, and that all the wires going in were in flex. Besides doing that I don't think that there is anything I could do except change a transformer. That would cost a bunch and it's in a room that nobody works near anyway. Is loud transformer noise a sign of an imminent failure? or Will the transformer continue to work for a long time and just be loud? Any suggestions?
Thanks
