About the product
- 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
The TDS NT combination system for cable testing and cable diagnosis offers you the highest degree of flexibility. The TDS NT consists of a multifunctional, compact voltage source and a modern PD detector. The TDS test voltage source can be used for both simple VLF tests or for commissioning tests with accompanying PD diagnosis in connection with the PD detector.
Thanks to the TDS NT's latest 50 Hz Slope Technology, it has become possible to immediately locate faults in underground cables during the actual PD measurement. With the 50 Hz Slope Technology, a withstand test with VLF cosine-rectangular voltage (VLF CR) and PD diagnosis with damped alternating current (DAC) is combined in one unit. This gives you an efficient and integrated solution for precise inventory of the network infrastructure. The important fact here is that the PD measurement data, gained with the VLF CR or with the DAC test voltage, can be compared directly with the 50/60 Hz network voltage. This facilitates reliable decision making.
For comprehensive coverage, pair the TDS NT with Megger’s partial discharge solutions, including test sets, monitoring devices, and sensors for complete network diagnostics.

Software and firmware updates
PD Software
Version 4.x.x requires the additional purchase of a new digital license key. This version does not support the older PD Software V3.x.x dongle license key system.
PD Detector Software Setup
- Resolves the issue with the version conflicts of PDv4 (license) down to the PDv3 (dongle)
- Customers who use the Centrix Evolution with the newest GPSP and PDv4 are able to export data from the van and import it to the older Windows PD software v3.5.12.
