Grid and Transformer Protection:

  • Blocks Geomagnetic storm Induced Currents (GIC) and EMP-E3
  • Capacitor blocking – all harmonics stopped regardless of solar storm or EMP size
  • Prevention of transformer half cycle saturation, Harmonic generation and thermal damage
  • Transformer neutral line always tied to ground
  • Automatic sensing of GIC or EMP/E3 induced quasi-DC currents in transformer neutral
  • Continuous operation even through ground faults
  • System operator override of automatic protection
  • System operator controlled switch reclose
  • EMP/IEMI protected electronics
  • Factory assembled solution ready-for-installation on concrete piers
  • Ferro resonance protection included
  • DC switch
Grid and Transformer Elcotromagnetic protection

The Emprimus SolidGround™ Neutral DC Blocking System automatically blocks DC currents from flowing in the neutral of large power transformers protecting against Geomagnetic Storm Induced Currents (GIC) and Electromagnetic Pulse (EMP) induced currents of any size.
