INTELLIGENT CATHODIC PROTECTION DEVICE WITH ADAPTATION TO STANDING CURRENTS IN THE AREA OF ELECTRICAL INSTALLATIONS AND RAIL TRANSPORT Russian patent published in 2023 - IPC C23F13/02 

FIELD: corrosion protection.

SUBSTANCE: method used to protect gas pipelines, oil pipelines and other underground metal structures. The device contains a transformer, a rectifier, a filter, anode grounding switches, power switches, valves, integrators, sensors and protective potential settings, corrosion monitoring elements, corrosion monitoring switches, resistance meters, a measurement synchronization unit, a delay line, longitudinal and transverse correction elements, potentiometers in relation to electrical installations and rail electric vehicles, correction amplifiers, a control adder for protective potential correction setters, emergency potential value setters, display units and a radio transmitter for emergency potential values.

EFFECT: increasing the efficiency of cathodic protection against corrosion by adapting to stray currents in the area of operation of electrical installations and electric rail vehicles and timely detection of dangerous values of stray currents in cases of disruption of electrical installations.
