ADAPTIVE SYSTEM OF AUTOMATIC CORRECTION OF CATHODE PROTECTION STATIONS OPERATION Russian patent published in 2017 - IPC G01N17/00 C23F13/02 

FIELD: electricity.

SUBSTANCE: system contains the master and slave cathode protection stations, adjustable initial protective potential setting devices, reference electrodes, remote point potential reference units, communication line, power modules, load cells of power modules, reference electrodes, calibrating amplifiers of remote point potentials, calibrating amplifiers of potential of slave cathode protection stations, calibrating amplifiers of the potential of the master cathode protection station, calibrating amplifiers of the load cells of the power modules of the master and slave cathode protection stations.

EFFECT: improved protection of a gas pipeline from corrosion by controlling the values of the protective potential along the length of the gas pipeline and in remote points to maintain a uniform distribution and the amount of load of the master and slave cathode protection stations when working for a single gas pipeline to compensate for the impact of external non-stationary electric fields from different sources.
