Selection Requirements You should have the following information before selecting a buck-boost transformer. Line Voltage The voltage that you want to buck (decrease) or boost (increase). This can be found by measuring the supply lineFor three phase, 120V line-to-neutral, the line-to-line voltage is 208. Normal domestic power in North America is single phase from a center-tapped transformer, with the center tap being neutral. In this case, line-to-neutral is 120 V (half the transformer secondary), and line-to-line is 240V (across the full transformer secondary).

You need a step up transformer, 208 to 480 volt with a delta primary and a wye secondary if the machine is not dual voltage. You can get away with reverse feeding a 480 to 208 transformer, but the 480 volt side is typically a delta winding and you would need to either make it a corner grounded system or provide ground detectors to indicate a ground fault on an ungrounded 480 volt system.

I'll be honest i do electrical work everyday but rarely need a step down xfer. So my question is what size 480 breaker do I need to feed the primary side of the transformer in order to get 200 amp 208 on the secondary. And the size of the xfer itself is needed.be 480V input with 120/208V output, where the grounded conductor (neutral) on the 120V output is common with all three lines (Phases). A three phase transformer can be constructed either by connecting together three single-phase transformers, thereby forming a so-called three phase transformer bank, or by using Jul 31, 2018 · So this transformer is what we would normally think of as a 208V to 480V step _up_ transformer even though power is flowing from the 480V side to the 208V side. Remember that transformers are bidirectional; what differentiates the primary from the secondary is leakage inductance to limit inrush current when you energize the thing and which coil ...
