AC MITIGATION INSTALLATIONS
Electrical energy from a power transmission line can affect the pipeline by conductive coupling 
(during fault conditions), electrostatic or capacitive coupling and electromagnetic or inductive coupling. How those couplings affect the pipeline and the magnitude of the affect could be predicted by using AC modelling.
Once the magnitude and the reason of the AC interference are solved, then mitigation technics implemented to the system. There are many ways to mitigate; the main one is grounding the pipeline and a few other methods are used to overcome this problem. For example;
- Grounding the Pipeline by Means of Buried Horizontal Wires, Galvanic Anodes etc.
- Discrete Anode Groundbed
- Distributed Anode Groundbed
- Parallel Copper Cables Connected to a DC De-Coupler
- Bonding the Pipeline; Making the Pipeline Electrically Long or Lossy Pipeline
- Combination of the Above Points
We offer all kind of mitigation installations indicated above with our experienced CP certified engineers and technicians.
