Beschreibungen/Notizen

• The method for the estimation of remaining life or better for an increased risk of operation gives the user a structured way for assessing the condition of an underground cable circuit or a cable network, taking into account the past loading and the expected future loading of this circuit. Each component of the subjected circuit is analyzed, taking into account potential causes for deterioration (weak spots or defects) and methods for analyzing the effect of these defects on the degree of degradation. The analysis methods consist of desktop studies, on-site (diagnostic) measurements and laboratory measurements. Each analysis method has its own effectiveness, a measure for the certainty of the outcome and efficiency, being the ration between effectiveness and costs. The analysis methods with the highest efficiency should be applied at first, resulting in a certain degree of degradation and in remaining life, in dependency of the future load and of the past load.
