<P>PROBLEM TO BE SOLVED: To provide a more suitable method of countermeasure to electrolytic corrosion by quantitatively performing the specification of a cause for electrolytic corrosion, and synthetically evaluating the specification of the cause for electrolytic corrosion and grasp of the electrolytic corrosion condition. <P>SOLUTION: The system is provided with an instrumentation control section 20 and an operation process control section 21. The electric potential E<SB>ON</SB>to ground of subject piping 1 and a probe current I are inputted to the instrument control section 20, and simultaneously, the electric potential E<SB>R/S</SB>to ground of the rail 30 of a DC electric railway considered as the cause for the electrolytic corrosion in the piping 1 is inputted thereto. In the operation process control section 21, ultimate treatment of obtaining the correlation between the electric potentials E<SB>ON</SB>and E<SB>R/S</SB>to ground is performed, and further, electrolytic corrosion condition deciding treatment of comparing the probe current I with a decision standard is performed. <P>COPYRIGHT: (C)2004,JPO |
