Li. Freiman, A simple substantiation of monitoring the cathodic protection of underground pipelines by potential sensors, PROT MET R, 37(6), 2001, pp. 605-607
The base principle of monitoring the effectiveness of the cathodic protecti
on of underground steel Pipelines by the potential of a special sensor with
switching-off the sensor-pipeline circuit is substantiated. The principle
is correctly defined; and it is stated that the problem of the sensor size
remains unsolved.
