120/240 single phase. 120/208 3 phase. 277/480 3 phase. The 120/240 configuration is obtained from the low-side of a HV/240 volt transformer, where HV is the rated voltage on the high voltage side, and the 240 is the rated voltage on the low voltage side. Then a center tap is connected to the low voltage winding and grounded along with the low ...

The fans on high MVA autotransformers and some oil pumps can be rated at 480 Volts. The 240/120 volt Delta and 240/120 volt Wye connections are common three-phase AC station power connections since they can also supply 120 volts when it is a four wire connection. Standard three-phase AC sources can be obtained with a three-phase transformer, a three-phase banking of single-phase transformers ...
