description PURPOSE:To accurately measure the potential of a metal structure by using a potential current detector having a standard electrode of which outer circumference is covered with the same metal as that of the metal structure to be measured. CONSTITUTION:A potential current detector 1 has a standard electrode 10 of which outer circumference is covered with the same metal (e.g., Ti) 7 as that of a metal pipe to be measured (cooling water pipe) 8. This potential current detector 1 is used by being installed, to be freely installed, removed and replaced, to a flange 5 installed to a water chamber cover 4 composing a water chamber 3 of a condenser 2. This potential current detector 1 is at a distance of l from the nearest insoluble electrode 18 for supplying a corrosion-proof current, and detects the same potential and current of a cooling water pipe 8 which is at a distance lfrom the insoluble electrode 18 in the same water chamber. Based on the measured value of the potential current detector 1, it is arranged so that a corrosion-proof current at a proper potential can be supplied.
