2 150kva generators feeding a 1200 amp service

  1. Oct 30, 2008 #1
    Can I feed a 1200 amp 3phase AC electrical service with 2 seperate 150kva power sources? (the sources being 150kva 120/208 3phase gas powered generators) Are there any issues with harmonics from seperately derived systems? Will each phases voltage still be 120v or by combing 2 seperately derived phases will the voltage become 208v or 240v etc?

    What voltage is the service?
    What is the power factor of the load?

    If you use two generators in parallel, they must have the same phase angle, voltage, and frequency (or really close to it) before you parallel them.
