Description
Baur/HVT 411+067 – PD-TaD 62 PD Diagnostics System
- Comprehensive 360° cable analysis – with parallel partial discharge and dissipation factor measurement*
- Time-optimized and safe cable condition evaluation
- Lightweight and compact for mobile use on site
The PD-TaD 62 portable PD diagnostics system is used in combination with a BAUR VLF generator for carrying out:
- Partial discharge testing and location
- VLF cable testing with parallel partial discharge testing
- Parallel partial discharge and dissipation factor measurement
- Full MWT
With the partial discharge testing and the dissipation factor measurement, two effective and proven methods for evaluating the aging condition of medium-voltage cables and cable accessories have been combined in a single compact and portable device. The result is a one-step 360° cable analysis with early detection and localization of weak points through a PD measurement, in addition to the evaluation of dielectric aging based on the dissipation factor values.
The ability to perform partial discharge and dissipation factor measurements simultaneously saves a lot of time and leads to increased efficiency during inspection of the entire cable network. The simultaneous monitoring of tan δ values and PD activities, also helps detect hidden faults (e.g. moist joints).
Light, robust and portable: PD-TaD is ideal for mobile use in the field. The device and accessories are convenient to transport in robust transport cases.

Combination of methods for more significant information
With the BAUR PD-TaD 62, in combination with a BAUR VLF generator with tan δ measurement function, dielectric losses can be measured and the cable route can be tested for partial discharges during the VLF cable test. This combination of methods is called Full MWT and provides significantly more information than the cable test alone. While the cable test shows whether the cable system can withstand a load over a specified test duration, the dissipation factor measurement enables an evaluation of the condition of the cable insulation. Moreover, partial discharge testing shows and locates the PD faults precisely. The highlight of MWT is the condition-based test duration: Provided it is permitted, the test duration can be shortened, which in turn lowers costs. This way, the cable is only exposed to the increased test voltage for the required duration.
VLF truesinus® – A voltage shape for all methods and method combinations
VLF truesinus® is the only voltage shape that enables both reliable voltage tests as well as precise dissipation factor measurement and partial discharge testing. Unlike other voltage shapes, the VLF truesinus® voltage is load-independent, symmetrical, and continuous. This is a prerequisite for high precision as well as reproducibility and comparability of measurement results.
