I have a 112.5 KVA 277/480 primary, 120/240 secondary. I have 277/480 going in (double checked, all legs are the same around 277) but for the secondary, I have 120 on black, 212 on red, and 120 on blue (hot to ground). All line to line read around 240 though. Has anybody ever ran into this? I don't know why I have 212 on red. Taps are all set the same to 480 volts. Also, I know some transfomers hum pretty loud, but it seems to be humming a little louder than normal. Any feedback would be appreciated.
Thanks.
Thanks.
