I am working in an application that both single phase 120/240 and 3 phase 240/120 are to be available for load testing equipment. There are two separate load banks, sized to draw no more than 10 amps at 1 phase 120/240 and 3 phase 240. The test will not be conducted simultaneously.
I am proposing installing a 15 kVA 3 phase 240/120 transformer. All the 120/240 load testing would be performed on phases A & C due to the high leg. Would this imbalance cause early failure of the transformer and therefore not be advised?
My other option is (1) 15 kVA, 3 phase, 240 V xfmr & (1) 5 kVA, 1 phase, 120/240V xfmr.
Thanks,
