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 six line to neutral voltages are all 3.75 VAC, but the voltage between any two lines depends on the phase difference between them and can be 3.75 VAC (for 60 degrees), (3(3.75 VAC (for 120 degrees), or 7.5 VAC (for 180 degrees). Six phase AC is not just a laboratory curiosity.

Jun 17, 2002 · Disadvantages are that a step down transformer is required to get 120/208 or 120/240 volt power for lights and outlets. Motors should be started directly from the generator buss, not from a step down transformer to minimize voltage drop. 120/240V, 3 phase, 4 W Delta- This is the least desirable voltage to use if there is a large amount of 120 ...
