VLF cable testing with parallel partial discharge testing
PD-TaD 80
54 / 74
822-188-3
Whereas VLF cable testing shows whether a cable can withstand a load over a specified test
duration, PD testing identifies and locates the PD activities of the cable insulation.
The simultaneous performance of VLF cable testing and PD testing can reduce the test time
for cables that are in good condition.
1. Connect the test object for PD testing.
Further information: Chapter
Connecting the system for PD measurement
(on page 35)
2. Calibrate the PD test circuit.
3. Start VLF cable testing.
4. Configure and start PD testing in the BAUR software.
5. Monitor the trend of the PD measurement results during testing.
Information on calibrating the PD test circuit as well as performing
PD testing and VLF cable testing is given in the user manual for the
BAUR software 4.
Information on operating the cable test van or VLF HV generator is
given in the user manual for the cable test van or the respective
VLF HV generator.
