NEW TECHNICAL SOLUTIONS IN THE PRACTICE OF OPERATIONAL EVALUATION OF RESISTANCE OF PIPELINE INSULATION
(pp. 28-34)

Abstract. These volumes explore method for the rapid assessment of the insulation resistance of underground pipelines in order to reduce the duration and complexity of route work in the process of electrometric inspection of utilities. The idea of the method is based on the representation of a pipeline in the form of a metal-electrolyte electrochemical system, along the boundary of which a double layer of charged particles is formed, which can be logically represented as an equivalent electrolytic capacitor. This allows you to use the push-pull controlled discharge of the capacitor followed by mathematical processing of the two discharge equations and determine the absolute value of the insulation resistance of the pipeline in almost real time. The work provides a theoretical evaluation of the method and conducts a constructive and technological analysis of its practical implementation. The engineering calculation of the discharge resistance values confirmed the reliability of the proposed method for assessing the insuation resistance of pipelines.

Keywords: insulation, pipelines, circuitry, insulation resistance, transition processes, discharge time.
