The gradient control mat must be connected to the handle grounding conductor.
Gradient control mat design.
After welding the mat is hot dip galvanized.
Limitation capabilities are also factor in potential hazards such as lightning strikes and ground faults.
Maximizing gradient control mat safety by design.
The gradient mat must rest on 150 mm of crushed stone which lies on the ground.
The gradient control mat is made of 0 135 diameter steel wire with a 3 x 3 wire spacing with all wire intersections welded.
Each mat weighs 15 pounds 6 8 kg.
Mitigator gradient control map plan view.
The gradient control mat by dairyland is designed to limit step and touch potentials due to lightning because such design will also keep step and touch potentials well below that required by ieee 80 for power frequency voltages.
Dei offers engineered gradient control mats gcm to address lightning and ac fault current conditions backed by analysis from experts in lightning protection and with a full review by correng consulting of the cathodic protection guidelines of this mat design.

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.
Personnel working near pipelines protected by cathodic protection are subject to lightning ac fault current and steady state ac induction hazards.
Installing gradient control mat which is a system of buried bare conductors typically galvanized steel copper or zinc connected to the structure provides localized touch and step voltage protection by creating an equipotential area around the appurtenance.

Mats are available in 4 x 8 sheets and are shipped flat on pallets.
Step and touch potentials are now limited with the dairyland grid type mat in a much lower cost design.
The gradient control mat cannot be isolated from ground.
