CDA partial discharge diagnosis system for medium-voltage power cables
| |
| Applications: |
- Non-destructive quality tests of medium-voltage power cables and their accessories, such as joints and
terminations, subjected to a transient voltage stress of specified shape
- Complex analysis of the PD events is performed (Complex Discharge Analysis =CDA)
- Location of dangerous PD faults an user-friendly evaluation

| Mobility |
- test facility can be installed easily in cable test vans
- on-site tests can be performed independently from the mains, if supplied via low cost motor generator

| Philosophy |
- test level not higher than 2 Uo
- low number of tests shots is sufficient for the indication of dangerous PD
- PD detection is performed in the tail region, when the cable capacity is discharged
- the power demand for charging the cable capacity becomes extremely low
- procedure can be run either manually or automatically controlled by the computer
- dangerous insulation defects are located semi-automatically, based on the program CDA-Exploration
