FIELD: metalwork corrosion protection systems, mainly sea-going vessels. SUBSTANCE: corrosion protection system is provided with reference electrodes of different polarity of potential (for example, silver-chloride and zinc electrodes). Device has controllable DC source, control unit and source of adjustable stabilized voltage. Positive and negative DC outputs may be connected to anode of system and to ship's hull, its input being connected to output of control unit. One pole of source of adjustable stabilized voltage is connected to input of control unit of similar polarity; other pole is used as input of device for connecting the potential sensor of system of different polarity as compared with control unit. Magnitude of stabilized voltage of source is no less than magnitude of stationary potential of ship's hull. EFFECT: extended technical capabilities. 1 dwg
