3 Phase Isolation Transformer Grounding

  • Grounding Transformer | Ground Isolation Transformer .

    A properly designed and installed grounding transformer will protect an isolated three phase system in the event of a line-to-ground fault by providing a low impedance path to ground for ground fault currents to flow while prohibiting voltage rise in the un-faulted phases and accommodating the connection of phase-to-neutral loads if required.
