Fault location

Sometimes, Cathodic Protection systems may develop faults which can be detected aftter the start-up and during operation of the system.
These faults are likely to prevent or reduce the efficiency of the Cathodic Protection system.
In most cases, these kind of problems are caused by faulty insulating joints, contact with other metallic structures (such as foreign pipelines), cables, sheet piling, reinforced concrete structures, and casings etc., or can even be due to the presence of insulating valves and expansion joints.

It is not always easy to determine the location of such faults. However, GCP is able to provide various proven measuring methods and together with the qualified services of its experienced personnel, are able to determine the location and removal of such trouble spots in minimum time.
