    3-phase transformers
    Consider a system with the one-line diagram shown below. The three-phase transformer
    nameplate ratings are listed. The transformer reactances are given in percent: 10% = 0.1
    p.u. The transmission line and load impedances are in actual ohms. The generator
    terminal voltage (magnitude) is 13.2 kV (line-line).

    A-B Transformer: 5 MVA, 13.2 kV/132 V, leakage reactance 10%
    B-C Transformer: 10 MVA, 13.8 kV/69 V, leackage reatance 8%

    Assume Sb=10 MVA.

    Find the generator current, the transmission-line current, the load current, the load voltage, and the power delivered to the load.

How to go from 200Amps/208V/3 phase to 600Amps/480V/3 phase [ 2 Answers ]

I am starting a business and have equipment that requires 600Amps/480V/3 phase, but the site I want to rent has only 200Amps/208V/3 phase. Is there anything I can do to get the required power on that site? Any equipment I can buy to achieve this goal? I understand it may be costly. Thank you.
