<P>PROBLEM TO BE SOLVED: To immediately improve a prevention state of cathodic corrosion that is deteriorated against an object to be prevented from cathodic corrosion in which cathodic corrosion is prevented by a sacrificial anode method, without large construction such as resolution construction of metal touch. <P>SOLUTION: The configuration for the method and the system for controlling the prevention of cathodic corrosion, comprises, a DC power supply system 3 that specifies a sacrificial anode 2 installed, as an anode, and an object 1 to be prevented from cathodic corrosion, as a cathode; a measuring means 4 for measuring a potential between the object and an electrolyte under in a state that a voltage from the DC power supply system 3 is applied and measuring the current of the sacrificial anode; and an operation processing means 5 for operating measurement data provided by the measuring unit 4. A potential P/S between a pipe and the earth is measured by connecting a wire W3 of which the top end is connected to a connecting section 1B, via a DC voltmeter 4A to a reference electrode (a saturated copper sulfate electrode) 6. <P>COPYRIGHT: (C)2008,JPO&INPIT |
