Partial Discharge Diagnostics
Partial Discharge (PD) testing is a proven diagnostic method for non-destructive cable testing for many years. Using partial discharge measurement with source localization, direct allocation of partial discharge activity on cable segments, joints or cable terminations is enabled. The following can be detected with PD testing:
- Defects in joints and terminations
- Defects in polymeric cables, such as electrical trees
- Insufficient oil insulation in PILC cables
- Mechanical damage of the cable sheath
The patented truesinus® voltage generation technology provides a precise basis for significant and reproducible results so that reliable comparisons and trend analysis can be conducted.
