摘要
The method of continuously monitoring the passive corrosion protection involves detecting the pulse reflection image between the two metal casings (3, 5) enclosing a corrosion protection casing (4). A reflection measurement device is coupled to the metal casings via a power isolation filter and a capacitor. The original image for constant pulse frequency and shape is stored on a data medium by a computer. The images acquired during operation, which can also be stored, are compared with the original image and deviations used to detect corrosion protection damage. USE/ADVANTAGE - For monitoring non-metallic corrosion protection casings between metal casings of high voltage, high power cables during operation without such disadvantages as high cost, lack of earth protection and ambiguous results.
