Zigzag Transformers (Grounding)

Mag-Tran's Zigzag transformers are often used to establish a ground where one is not present.

  • Customer defined continuous current, system voltage, fault current, and fault duration
  • Customer optionally defined X/R ratio and Zero Phase Sequence impedance
  • Often used in conjunction with a Neutral Grounding Reactor
  • Available open frame or in a NEMA rated enclosure with or without additional options
