Close interval potential survey (CIPS) – Direct Current Voltage Gradient (DCVG)
The underground pipe inspected by CIPS and DCVG method.
- CIPS technique evaluates the pipeline protection level and may indicate the present coating faults through pipe to soil potential
- DCVG is a coating fault locating technique. The DCVG technique is a method for detecting Cathodic Protection current pickup at coating holidays
- The Close Interval Potential Survey (CIPS) and Direct Current Voltage Gradient (DCVG) Survey are two techniques that work together using the pipeline's Cathodic Protection System to evaluate its protective efficiency and its coating conditions.
