Description
verview of TDS NT
- Two proven voltage wave shapes in one device
- Standard compliant VLF cable testing with accompanying PD diagnosis
- Non-destructive PD diagnosis by means of proven DAC voltage
- 50 Hz Slope Technology for a direct comparison with the power frequency
In addition to the proven VLF and DAC test voltage the TDS can also be used for DC tests and sheath tests in compliance with IEC 60229.It can be used to test cables according to the international standards (e.g. IEC 60502-2 and IEEE 400.2) with VLF-CR. In addition, a PD diagnosis using the new 50 Hz Slope Technology, can be performed simultaneously with the help of the PD detector. Alternatively, the TDS NT can also be used for PD diagnosis with the proven damped AC voltage (DAC).
PD Detector PDS 60 Features
- Suitable for DAC, VLF CR and VLF Sinusoidal power sources up to 60 kVrms
- Powerful database. Simplified searching, browsing and administration of measurement and cable data.
- Fully automatic calibration with the option of calibrating according to cable length or propagation velocity.
- Clear display of measurement results and live PD localization. A time-consuming post-processing of the measured data is no longer necessary.
- Report generation by mouse click.
- Real-time data evaluation and display of results, no post processing needed
- General and localized Phase Resolved PD pattern (PRPD) display for defect type recognition
PDS 60 has become possible to immediately locate faults in underground cables during the actual PD measurement.PD detector software will support the user with the data evaluation by means of so called Phase Resolved Partial Discharge (PRPD) patterns. With help from these PRPD patterns the user is able to distinct between different types of PD defects, such as corona or internal PD. This is of major importance for partial discharges located at terminations; corona discharges are not problematic, where-as internal PD would.
