Cathodic Protection Grid Survey
Your facility is subdivided into an appropriate set of panels to allowthe work to be completed in stages. Each test panel’s location andorientation within the plant are documented. While panel sizes canbe different for different facilities, spacing between data collectionpoints is always the same. This enables reassembly of multiplepanels into a large map for the entire facility.
The survey can be completed with the cathodic protection systemon, off or interrupted, depending on which information is mostimportant. Thresholds are set and assigned specific colors toenable fast detection.
Everything is then graphically displayed in an easy to understandheat map for analysis.
- Identify areas that do not demonstrate adequatecathodic protection.
- Locate unintentional shorts, grounds and interconnects.
- Select and prioritize plant locations for excavation anddirect examination.
