SYSTEM FOR PROTECTING PIPELINE FROM INDUCED ALTERNATING CURRENT

摘要

FIELD: physics. ^ SUBSTANCE: invention relates to protection of metal articles from corrosion. The protection system has a support on which there is a contact terminal and an electricity box housing a capacitor unit for carrying alternating current to an earthing device and preventing direct current leakage of electrochemical protection of the pipeline, apparatus for filtering the tapped current at a fixed current, a device for measuring the tapped current and a device for protection from surge overvoltage. ^ EFFECT: high reliability of the system for protecting a pipeline from induced alternating current and simplification of the apparatus. ^ 2 dwg
