What is cathodic protection measurement?

Cathodic protection measurement is a test performed to check whether metal pipes, tanks, or structures are adequately protected against corrosion. The aim is to prevent the metal from rusting (corrosion) and to extend the life of the facility. Why is it done?

To prevent corrosion of underground/aboveground metal installations

To ensure safety in gas, oil, and water pipelines

To check compliance with standards and regulations

How is it done? (Briefly)

Potential measurement

Reference electrode (usually Cu/CuSO₄) is used

Metal-to-ground potential is measured

Check the adequacy of protection

The measured potential is compared with standard values

Anode or current adjustment is made if necessary

Visual and connection check

Anodes, cables, and connections are checked

How often is it done?

At least once a year

It is repeated after maintenance or a malfunction

Standards

TS EN 12954

NACE / ISO standards

Who should do it?

The work must be carried out by authorized Electrical Engineers, Electrical and Electronics Engineers / Electrical Technicians who have a Ekipnet "K" number.
