Accurate cable diagnostics are essential for utilities and service teams that need to identify insulation problems before they turn into failures. The BAUR PD-TaD 62 is a portable partial discharge diagnostics system designed for use with a BAUR VLF generator to carry out partial discharge testing and location, VLF cable testing with parallel partial discharge testing, parallel partial discharge and dissipation factor measurement, and Full Monitored Withstand Test (MWT). BAUR presents it as a compact solution for more complete medium-voltage cable condition evaluation in the field.
One of the biggest strengths of the PD-TaD 62 is that it combines two proven cable diagnostics methods in one workflow. BAUR explains that partial discharge measurement helps with the early detection and localisation of weak points, while dissipation factor measurement helps evaluate dielectric ageing in the cable insulation. When these measurements are performed simultaneously, users gain a more complete 360 degree cable analysis, while also saving time during inspection of the cable network. BAUR also notes that simultaneous monitoring of tan delta values and PD activities can help reveal hidden faults such as moist joints.
The PD-TaD 62 is designed for condition evaluation of medium-voltage cables and cable accessories. According to BAUR, the system supports diagnostics of local weak points, location of faults in cable insulation, joints, and terminations, as well as measurement of PD level and frequency, PD inception and extinction voltages, and phase-resolved PD patterns for classifying fault locations. This makes it a valuable tool not only for confirming that a cable system has a problem, but also for understanding the type and position of the defect more clearly.
A major practical advantage is efficiency. BAUR emphasizes that parallel partial discharge and dissipation factor measurement shortens testing time because both diagnostics methods are performed at the same time. The product page also highlights time-optimised and safe cable condition evaluation, while the datasheet notes that automated sequences and report generation help save time on site. For service teams working under outage pressure or maintaining large cable networks, this faster workflow can be a significant benefit.
The PD-TaD 62 is also built for portable field use. BAUR describes it as light, robust, and portable, with the device and accessories supplied in robust transport cases for convenient transport. The datasheet lists the PD-TaD 62 itself at approximately 17 kg, or about 17.5 kg including the HF filter, with an IP54 protection rating. This makes it practical for mobile use on site while still delivering the performance needed for advanced diagnostics.
From a technical standpoint, the PD-TaD 62 offers strong measurement capability. BAUR specifies PD measurements up to 44 kVrms / 62 kVpeak, a PD measurement range of 1 pC to 100 nC, sensitivity of 1 pC or better, sampling at 100 MSamples/s, and a theoretical partial discharge location range from 10 m to 12,800 m at v/2 = 80 m/μs. Accuracy for fault location is given as approximately 1 percent of cable length, with 0.1 pC / 0.1 m resolution. These specifications support precise diagnostics and useful fault-location insight in medium-voltage cable systems.
BAUR also highlights design features that help improve signal quality and test reliability. The PD-TaD 62 includes a coupling capacitor, measurement impedance, and PD measuring unit in one device, along with an integrated filter for suppressing noise signals. The system uses Power over Ethernet (PoE) for stable data transmission and power supply, so no batteries are needed for the PD measuring unit itself. BAUR further notes benefits such as galvanic isolation between the PD measuring unit and the laptop and a central power supply, both of which contribute to excellent noise suppression in field diagnostics.
Another important benefit is its integration with BAUR Software 4. BAUR states that the software controls the entire measurement process, allowing users to enter cable data, define test sequences, and run measurements automatically without manual readjustment. During testing, the software displays partial discharge levels, positions, dissipation factors, voltage curves, trend displays, and phase-resolved visualisations, while also supporting central documentation and report generation. This makes the PD-TaD 62 part of a broader digital diagnostics workflow rather than just a stand-alone instrument.
The system also fits into a broader structured process for cable diagnostics and fault follow-up. BAUR shows the PD-TaD working together with the cali calibrator for standard-compliant calibration and with the tracy PD signal coupler for pinpointing the exact location of a detected cable fault. In this workflow, the PD-TaD 62 is used to begin diagnostics, assess PD activity and dissipation factor values, and provide the information needed for reliable next-step decisions. This structured approach supports more confident and reproducible cable condition evaluation.
Standard delivery is designed to provide a ready-to-use diagnostics package. BAUR lists delivery items including the PD-TaD 62 portable PD diagnostics system, transport cases, HF filter, Power Box, cali PD calibrator, HV connection set with adapters, connection cable set, user manual, and a laptop with pre-installed Windows and BAUR Software 4. For organizations that need an integrated portable PD diagnostics setup rather than separate components from multiple vendors, this complete package is a meaningful advantage.
Overall, the BAUR PD-TaD 62 is a strong solution for utilities, contractors, and cable diagnostics specialists who need more than a basic partial discharge measurement system. By combining partial discharge testing and location with optional parallel dissipation factor measurement, automated workflows, and BAUR Software 4 integration, it supports a faster and more comprehensive approach to medium-voltage cable condition evaluation.
