Cathodic protection - common modern method of preventing corrosion of the pipeline due to the impact of various external factors. However, the system of cathodic protection is also subject to negative impacts of AC originating from surrounding objects. For example, from the railway nearby or power line passing over the pipeline.

Анодный заземлитель - Anode ground electrode
To protect the cathodic system and the pipeline it is necessary to get rid of hazardous induced alternating currents, draining them into the ground.
Fortunately, there are devices that easily perform this function.
For example, LEUTRON PLPro (PipeLineProtection).
In addition to the current drainage, the device also includes protection from direct effects of lightning - a special gas-filled surge arrester is able to drain current up to 100 kA (10/350 ms)!
