The pipeline industry’s first engineered AC Mitigation grounding system, combining superior AC grounding performance with greater ease of installation and lower overall cost.
The Mitigator utilizes copper as the grounding wire instead of zinc ribbon which has historically been used.
Unlike the zinc ribbon, which is typically installed in native soil without an enhanced backfill, The Mitigator® comes packaged with a special coke grounding backfill. This grounding backfill increases the grounding surface area of the gradient control wire to assure more intimate soil contact and to reduce the system resistance. The backfill also provides a uniform environment around the grounding conductor to assure even AC current discharge. Finally, the backfill has a corrosion inhibitor additive to further extend the life of the grounding system.
Copper has long been used in industrial grounding systems because of its significantly lower impedance as a conductor. The impedance of copper is three and a half times lower than that of zinc. This impacts the conductor’s performance during conductive fault events and serves to increase the propagation properties (the spacing of the grounds through DCDs) of the conductor during steady state inductive coupling. In addition, copper is significantly more inert (corrosion resistant) than zinc when buried – assuring that the copper grounding will have longer life than an equivalent zinc grounding system.
