Laboratory and on site tests for the determination of the ageing condition of MV PILC cables

In the major cities in Europe the electrical distribution network was firstly established at the beginning of the past century and it is not unusual to find electrical components having a service life of sixty - seventy years, still having a failure rate non dramatically higher than younger components. As a consequence the electrical Utilities are looking for methods/tools able to quantify the real ageing state of equipment and to propose a priority list for their replacement.
