A METHOD FOR ADAPTIVE ESTIMATION OF POLARIZATION POTENTIAL STABILITY USING ELECTROCHEMICAL PROTECTION OF UNDERGROUND STRUCTURES
This paper describes a method for estimating polarization potential, where the choice of estimation delay time is made taking into account the estimation results the fall time of the resistive component to the total capacity of a particular structure utilized for assessment of the potential. We provide pictures of the potential curve taken by the digital oscilloscope on the real pipeline. These pictures show the characteristic curve which determines the time behavior of the potential in the subsidiary electrode after it is disconnected from the protected the AP.
