I hope this is the proper forum for this question. I have three single phase transformers connected in delta - delta. The primary is 2300V, the secondary is 460V. The center of one transformer secondary winding (x2 and x3) is grounded. I'm reading 470V between all 3phases. A and C phases to ground read 235V, and B to ground reads 400V. This is the first time I've seen a set up like this. Can anyone tell me if these readings are correct. Thanks
