On-site testing of cable systems after laying, monitoring with HF partial discharge detection

At KEMA, a new high frequency measuring technique is developed to detect partial discharges in HV polymer insulated power cables and accessories. This complete system makes it possible to perform on-site PD measurements focused on accessories, without any connection to high voltage parts of the system. The measurements are based on newly developed techniques, while the PD determination is based on traditional rules because of the PD-phase-angle relation. The first field measurements with this complete system are presently being performed
