Megger TDS NT cable testing and cable diagnosis

Description

Unveiling the Next Generation of Cable Diagnosis

The landscape of network infrastructure demands increasingly precise and reliable information regarding the quality and condition of cables. The TDS NT emerges as the next generation in cable diagnosis, empowering network operators with faster and significantly more reliable insights. This leap forward is primarily attributed to the groundbreaking 50 Hz Slope Technology. For the first time, this innovative technology enables the immediate location of faults in underground cables directly during the Partial Discharge (PD) measurement process. This capability significantly reduces diagnostic time and enhances the accuracy of fault identification, paving the way for more efficient maintenance and infrastructure management. The traditional methods often involve time-consuming post-processing, which the TDS NT completely negates, leading to substantial resource savings and improved operational efficiency. The integration of such advanced features within a user-friendly system underscores the commitment to streamlining complex diagnostic tasks, making them accessible and efficient for a wider range of technical personnel.

The Unique “ALL-IN-ONE” Solution for Cables

The TDS NT series redefines flexibility in cable testing and diagnosis by offering a unique “ALL-IN-ONE” solution. This sophisticated system comprises a multifunctional, compact voltage source seamlessly integrated with a modern PD detector. This combination allows for a wide array of testing scenarios. The TDS test voltage source is versatile, capable of performing simple Very Low Frequency (VLF) tests, or, when connected to the PD detector, conducting comprehensive commissioning tests with accompanying PD diagnosis. Beyond these core functionalities, the TDS NT extends its capabilities to include DC tests and sheath tests, fully complying with IEC 60229 standards. Furthermore, in conjunction with the ESG NT step voltage sensor, it facilitates precise pinpointing of sheath faults, demonstrating its comprehensive utility in cable maintenance and fault location. This holistic approach significantly reduces the need for multiple specialized devices, offering a cost-effective and space-saving solution for network operators. The adaptability of the TDS NT ensures that it can address a broad spectrum of cable diagnostic needs, from routine checks to complex fault analyses.

Harnessing the Power of 50 Hz Slope Technology

At the heart of the TDS NT’s exceptional performance lies its innovative 50 Hz Slope Technology. Both the VLF voltage and the Damped Alternating Current (DAC) voltage, crucial for accurate diagnostics, operate on this principle. This technology is particularly vital for Partial Discharge (PD) diagnosis, as it ensures that the measured results are directly comparable with the power frequency. This direct comparability is a critical factor for reliable evaluation of PD characteristics, which are known to change significantly with large frequency differences, thereby making accurate assessment impossible. The 50 Hz Slope Technology meticulously maintains the comparability for both voltage waveforms, guaranteeing the integrity and reliability of the diagnostic data. This fundamental aspect of the TDS NT’s design directly addresses a long-standing challenge in cable diagnostics, providing a stable and consistent basis for evaluating cable health. By overcoming the limitations of traditional frequency-dependent measurements, the TDS NT delivers unparalleled accuracy and confidence in its diagnostic findings.

User-Centric Design and Integrated Software

The design philosophy behind the new TDS NT technology places a strong emphasis on the user experience. The operating software is intuitively designed to ensure immediate usability for any operator, regardless of their prior experience with similar systems. This user-centric approach is evident in several key features. An integrated database simplifies the searching, Browse, and administration of both measurement and cable data, streamlining the entire diagnostic workflow. The system boasts an improved fully automatic calibration process, complete with a clear display of the signal-to-noise ratio, enhancing the precision and reliability of measurements. A standout feature is “Real time” PD mapping, where the advanced PD evaluation algorithm enables reliable automatic detection and precise location of partial discharges as the measurement is actively taking place. This eliminates the need for time-consuming post-processing of measurement data, allowing maintenance resources to be scheduled directly and efficiently. Furthermore, reporting by mouse click allows operators to generate comprehensive reports with clearly structured summaries of important measurement data immediately after a test is completed, significantly improving efficiency and documentation.

Specific Applications of the TDS NT System

The TDS NT system offers a multitude of specific applications, making it an indispensable tool for cable maintenance and commissioning. One primary application is standard-compliant VLF cable testing with accompanying PD diagnosis. This allows for thorough assessment of cable insulation integrity and early detection of defects. Another crucial application is non-destructive PD diagnosis through the use of proven DAC voltage. This method allows for detailed analysis of partial discharges without causing further degradation to the cable. The 50 Hz Slope Technology enables a direct comparison of diagnostic data with the power frequency, providing highly relevant insights into the cable’s performance under actual operating conditions. Beyond core diagnostic functions, the TDS NT also supports DC tests and sheath tests in compliance with IEC 60229, crucial for verifying the integrity of cable sheaths and identifying potential vulnerabilities. When combined with the ESG NT step voltage sensor, the system becomes a powerful tool for precise pinpointing of sheath faults, minimizing downtime and repair costs. Furthermore, its ability to immediately locate faults in underground cables during PD measurement significantly reduces the time and effort required for fault finding, making it invaluable for preventive maintenance and rapid response to outages.

Maximizing Efficiency with High Test Capacitance

The TDS NT, particularly the TDS 40 and TDS 60 variants, is engineered for maximum efficiency, a critical factor in managing extensive cable networks. Thanks to its high test capacitance, the system guarantees standard-compliant 0.1 Hz VLF tests on long cables or multiple phases in parallel. This feature alone translates into considerable time savings for network operators, as it allows for the simultaneous assessment of larger sections of the network, significantly accelerating diagnostic workflows. The portable and easy-to-transport two-piece design further enhances its efficiency, allowing for quick deployment and maneuverability in various field conditions. An integrated leakage measurement provides a rapid first indication about the general condition of the cable, enabling quick assessments and prioritizing further diagnostic efforts. Furthermore, the highest safety is ensured through an integrated discharge unit, earth-loop monitoring, and breakdown detection, protecting both the operator and the equipment during operation. These features collectively contribute to a highly efficient and safe diagnostic process, optimizing resource allocation and minimizing operational risks.
