I have a piece of 3-phase equipment that draws 400A of 3-phase power at 208V. I want to put in a 3-phase transformer to get 208 from the 480. My calculation is as follows (ignoring transformer losses and assuming a balanced load): 480V 3P @200A = 166kVA 208V 3P @400A = 144kVA therefore the 200A 480V service has enough power. I consulted with an120/208V Single Phase Power. 120/208V single phase is derived from 208V three phase power. If viewed on an oscilloscope, the three voltage waveforms on the three "hot" conductors all peak at different times: each one is 120 degrees behind the next. When using 120/208V single phase, you will use any two of those same three hot conductors ...Step-Down Transformers reduce electrical voltage in an application. The 3-Phase design is more compact, cost-efficient, and lighter than three individual single-phase units used together. This design also promotes more efficient use of base materials, such as copper and iron ore. At Agile Magnetics, we use 100% pure copper windings to construct ...Today we're finally getting around to wiring up a transformer to power my 120V mill power feed from a 240V circuit.
