The new cable condition evaluation generation

  • Cable testing and dissipation factor diagnostics in one device
  • Easy and quick test setup
  • Automatic testing and diagnostic sequences
  • Compact dimensions and lightweight

The portable BAUR frida and frida TD devices are used

  • for testing medium-voltage cables and electrical equipment (generators, transformers and switchgear)
  • for cable sheath testing
  • for cable diagnostics (frida TD):
  • Dissipation factor measurement and Monitored Withstand Test with tan δ
  • Partial discharge measurement*
  • Full Monitored Withstand Test with tan δ and partial discharge measurement*

The VLF testing makes it possible to locate insulation faults in plastic- and paper-insulated mass-impregnated cables in the shortest of testing times without impairing the quality of the surrounding insulating material. The dissipation factor diagnostics with 0.1 Hz VLF truesinus® provides differentiated information on the ageing condition of paper-insulated mass-impregnated and PE/XLPE cables. In the case of PE/XLPE cables, the dissipation factor measurement is capable of differentiating between new, slightly or severely “water tree”-damaged cables. This makes it possible to prioritise the need to replace cables. The Monitored Withstand Test with tan delta combines the cable testing and dissipation factor measurement, allowing an accurate and comprehensive assessment of the cable condition. In addition, there is minimum load on the cable due to the optimised test duration.
