BAUR – PD-TaD 80
Description
PD-TaD 80
Portable PD diagnostics system
A new dimension in cable condition evaluation
↗ Better decisions based on a comprehensive condition evaluation of the cable network
↗ Saves time on site thanks to automated sequences and report generation
↗ Suitable for mobile use or system integration
The PD-TaD portable PD diagnostics system is used in combination with a BAUR VLF HV generator to perform partial discharge measurement and location.
When the VLF HV generator is equipped with a dissipation factor measurement function, two effective and proven methods for evaluating the ageing condition of medium voltage cables and cable accessories, namely PD measurement and dissipation factor measurement, can be combined. The result is a one-step cable analysis with early detection and location of weak points through PD measurement, in addition to the assessment of dielectric ageing based on the dissipation factor values.
The ability to perform PD and dissipation factor measurements simultaneously saves a lot of time and leads to increased efficiency during inspection of the entire cable network. The simultaneous analysis of dissipation factor values and PD activities also helps detect hidden fault locations (e.g. moist joints).
Light, robust, and portable: the PD-TaD 62 is ideal for mobile use in the field. The PD-TaD 80 is particularly suitable for integration in cable test vans.
