Gradient Control Mat

MITIGATOR Gradient Control Map Plan View

Personnel working near pipelines protected by cathodic protection are subject to lightning, AC fault current and steady state AC induction hazards. While typical gradient control mats (GCMs) have not always proven to be effective, the MATCOR MITIGATOR® is an ideal product for use in gradient control mat applications to protect workers from these hazards.

The MITIGATOR® Gradient Control Mat Benefits

  • Engineered grounding system with documented better performance vs. zinc or copper
  • Easy to install
  • Lightweight
  • Does not require anode to protect mat from corrosion
  • Pipeline CP readings can be taken in the
    vicinity of the mat

The MITIGATOR® Engineered AC Mitigation System gradient control mat configuration is recommended for these applications:

  • Test Stations along pipelines in a high voltage AC power line corridor
  • Around above grade to below grade interfaces in stations
  • At above ground appurtenances including blocking and metering valve sites

The MITIGATOR® Gradient Control Mat Installation

The MITIGATOR® is supplied on a reel for ease of installation. The GCM is laid out in concentric rings around the pipe or above ground appurtenance and connected to the pipe through a decoupler device.
