FIELD: construction.
SUBSTANCE: invention relates to devices for cathodic protection of underground metal structures. Proposed device comprises cathodic protection station to be connected to protected structure, control unit connected thereto, anode earthing device, measuring units with reference electrode and data transmission channel. Each measuring unit is equipped with an optical voltage sensor connected to a reference electrode, a protected structure and a data transmission channel. Data transmission channel is fiber-optic.
EFFECT: higher efficiency of monitoring of cathodic protection parameters.
