Measuring of very low resistance ranging from 0.01 ľOhm up to 20 mOhm
| |
| Applications: |
- Detection of partial discharge in respect to fault location in extra high and high voltage cable accessories; also in unscreened conditions
- PD-quality tests on laid cables before putting into operation (on-site)
- Continuos or periodic PD-monitoring on laid high voltage cable systems

| Characteristics: |
- Detection of the PD fault location by evaluation of the travelling direction of the impulses
- PD monitoring. recording and analysing for each PD-fault location referring to each location
- Distinction of noise pulses and PD by evaluation of the travelling direction of the impulses
- Measuring system works in frequency ranges of HF/UHF
