Diagnostic system for off-line diagnosis of MV cables

Actual condition and the remaining lifetime of medium voltage cables are of high interest for a condition based asset management. By the conduction of an artificial aging experiment on paper insulated lead covered cables, the aging behavior of this cable type could be pointed out. With this knowledge, a new project with the focus on application in field has been started. Within the project, a diagnostic system for off-line diagnosis of medium voltage cables has been developed. After a short description of the aging experiment and its results, the measurement system and some results from the field measurements will be presented.
