Dedicated On-Site Condition Monitoring of High Voltage Power Cables up to 150kV

摘要

For advanced, non-destructive on-site condition monitoring of HV power cables up to 150kVnby partial discharge detection and dielectric losses measurement it is necessary to energize thendisconnected cable system. One of the methods available for this purpose is based on applyingndamped AC voltages up to 150kV. In this paper, the use of modern technological solutions innpower electronics and signal processing as well as in technical design and production methodsnwill be discussed on the basis of the ultra light system (300kg) which is able to test cables up ton20km lengths.
