UHF PD-Diagnosis at high voltage cable terminations – International case studies
Different partial discharge defects show a different distribution in the frequency spectrum. These typical characteristics could be used in combination with the appropriate phase resolved partial discharge pattern for the analysis of partial discharge defects. The classification of the partial discharges allows an assessment of the defects in terms of its criticality.

Best practices for offline diagnosis of medium voltage cables
The continuously increasing installation complexity for medium voltage power cables, results in many weak spots and therewith cable failures due to bad workmanship. This is mainly caused by the large variety of cable accessories as well as the reduction in insulation thickness and therewith in the margin of error throughout the entire cable installation process. The necessity for both commissioning testing of new cables as well as diagnostic measurements as part of a condition based maintenance is just a logical given fact. Nowadays cable testing as well as condition monitoring are well proven measurement methods for MV power cables which are guided by IEEE 400 [1] and IEC 60502-2 [2] standards.
