Baur PHG 80 TD PD BAUR VLF test and diagnostics system

A Modular System for Comprehensive Diagnostics

In the demanding field of electrical maintenance and asset management, having the right tools for comprehensive diagnostics is crucial for ensuring the reliability and longevity of a network. The BAUR PHG 70 TD PD and PHG 80 TD PD systems represent a new standard in this area, offering a flexible and modular approach to cable testing. These systems are not just simple high-voltage generators; they are integrated platforms for a wide range of diagnostic functions, including cable testing, dissipation factor measurement, and partial discharge analysis. The inherent modular design is a key differentiator, allowing a user to acquire a base system for their immediate needs and then easily extend its capabilities at any time as their requirements evolve. This scalability ensures that a utility or service provider can tailor their system configuration precisely to their budget and operational needs, without having to purchase a new, more advanced unit later on. The ability to perform a variety of tests on both plastic- and paper-insulated cables in the shortest possible time, without causing damage to the surrounding insulating material, makes the PHG series an essential tool for modern maintenance and fault-finding strategies.

The Superiority of VLF Truesinus Technology

The technological heart of the PHG series is the exclusive VLF truesinus® testing technology. This is far more than just a voltage source; it is a meticulously engineered solution that provides a single, unified platform for all test methods and their combinations. The VLF truesinus® voltage shape stands apart from others because it is load-independent, symmetrical, and continuous. This perfect waveform is a fundamental prerequisite for achieving high precision, as it eliminates the distortions and inconsistencies that can arise when testing long or highly capacitive cables. Unlike square wave voltages that can introduce undesired effects like space charges in the insulation, the symmetrical sine wave of the truesinus® voltage prevents such issues, ensuring a clean and reliable test. This unique characteristic guarantees the reproducibility and comparability of measurement results, a vital feature for creating a comprehensive cable database and conducting trend analysis. By providing a stable and uncompromised voltage source for all tests, from simple withstand tests to complex partial discharge measurements, the VLF truesinus® technology ensures that professionals can make accurate and data-driven decisions about their network’s health.

Tiered Solutions for Every Diagnostic Need

The modularity of the PHG system is brilliantly executed, providing professionals with tiered solutions that perfectly match their diagnostic needs. The base models, the PHG 70 and PHG 80, are powerful test generators used for fundamental cable and cable sheath testing of medium-voltage cables. They offer three voltage shapes—VLF truesinus®, VLF square wave, and DC voltage—to suit a wide range of cable types. For a more in-depth analysis of cable condition, the PHG 70 TD and PHG 80 TD models extend the functionality to include dissipation factor (Tan Delta) measurement. This addition provides a more differentiated view of the aging condition of both paper-insulated mass-impregnated cables and modern PE/XLPE cables. The top-tier models, the PHG 70 TD PD and PHG 80 TD PD, go a step further by integrating partial discharge (PD) testing. This capability allows for the fast and reliable evaluation of PD activity and, critically, the location of PD faults. This progressive modularity allows a user to start with a system for basic testing and gradually upgrade to a full-fledged diagnostic solution, making it a highly flexible and cost-effective long-term investment.

Assessing Insulation Health with Dissipation Factor

The dissipation factor (Tan Delta) measurement capability of the PHG 70/80 TD models provides invaluable insights into the overall health and aging of cable insulation. The test, performed with the highly precise 0.1 Hz VLF truesinus® voltage, measures the dielectric losses in the insulation. A higher dissipation factor indicates that the insulation is degrading, possibly due to moisture ingress or aging. The PHG system can perform this measurement with an exceptional precision of 1×10−4, ensuring highly accurate results. This precision is particularly beneficial for PE/XLPE cables, where the presence of “water trees”—microscopic channels formed by moisture—is a common problem. The dissipation factor measurement can reliably differentiate between new, slightly damaged, or severely “water tree”-damaged cables. This diagnostic data is crucial for maintenance planning, as it allows operators to prioritise the need to replace cables. Instead of relying on a simple pass/fail test, which might not reveal a developing problem, the dissipation factor measurement provides a quantitative assessment of the cable’s condition, enabling proactive maintenance and preventing costly failures before they occur.

Pinpointing Faults with Partial Discharge Testing

Partial discharge (PD) testing is a powerful diagnostic method that can detect early signs of insulation failure that other tests might miss. The PHG 70/80 TD PD models integrate this capability seamlessly, allowing for a fast and reliable evaluation of partial discharge activity. The system measures critical parameters such as PD level, PD quantity, and the inception and extinction voltages. This data provides a comprehensive picture of the PD activity within the cable. More importantly, the system’s ability to perform PD phase resolving is a game-changer. This advanced feature allows for the classification of different types of PD faults and, using a patented technology, their precise location along the length of the cable. The location accuracy is approximately 1% of the cable length, which drastically reduces the time and effort required for fault finding and repair. By recognizing potential faults early and accurately locating them, technicians can perform targeted repairs, reducing further damage and extending the operational life of the cable. The system also complies with IEC 60270 for partial discharge testing and calibration, ensuring that the results are reliable and recognized by industry standards.

Intuitive Software and Comprehensive Safety

The power and complexity of the PHG system are balanced by a user-friendly and intuitive design. The user interface, available in multiple languages, is adapted to the logical workflow of a test procedure, making it easy to operate even for new users. The system’s software is a key component, allowing users to store all key cable data and the results of every test and measurement. This creates a comprehensive cable database, which enables powerful trend analysis and historical comparisons. Operators can monitor the condition of a cable over time and make informed decisions based on its performance history. Safety is also a top priority, with a comprehensive safety concept that includes an automatic discharge unit. This unit automatically dissipates the residual energy after a test, ensuring a safe environment for handling the equipment. The system’s compact and modular design, combined with its high-performance capabilities, also makes it an excellent choice for installation in cable test vans, creating a fully equipped and mobile diagnostic station for field professionals.
