FAQ

When properly designed and implemented, cathodic protection systems can provide effective protection for up to 20 years. Anode type, soil structure, and maintenance frequency directly impact this period. System performance should be monitored with regular CIPS measurements.

DCVG (Direct Current Voltage Gradient) measurement detects coating damage using direct current signals, while ACVG (Alternating Current Voltage Gradient) uses alternating current to identify deeper and larger defects. ACVG is generally preferred for high-voltage lines.

CIPS measurements should be performed at least annually after system commissioning. Repeat measurements are recommended, particularly during seasonal transitions and after system updates. This ensures verification of protection levels and early detection of potential malfunctions.

Anode placement, cable routing, test box location, and occupational safety measures are critical during the installation process. Furthermore, equipment appropriate to the soil structure must be selected and the system must be tested before commissioning.

If the protection potential decreases, CIPS measurements will show non-standard values. Furthermore, if coating damage is detected during DCVG/ACVG checks, the effectiveness of the system should be questioned. In this case, maintenance or a system update may be necessary.
