  • Partial discharge diagnosis using VLF Sine wave, Damped AC or 50/60 Hz Slope technology voltages

Cable Test and Diagnostic System – PD, VLF Sinus, VLF CR, DAC, Tan Delta

TDM 45 series is a revolutionary breakthrough in testing and diagnosis of MV cables. The patented concept addresses the utilities increasing need for flexibility in use of test and measuring equipment based on the type of application.

The modular concept alloows the engineer to individually setup the unit based on the type of job that needs to be executed, e.g. for tanDelta diagnostics, PD diagnostics or VLF withstand testing. The TDM 45 series is available in eight varients; upgrades are possible without sending the unit back to the factory.

  • Cable testing, cable diagnosis and sheath testing in one device
  • Enables standard compliant high power VLF testing at 0.1 Hz (5 µF @ 40 kVrms)
  • Internal tanDelta measurement with automatic result interpretation according IEEE 400.2
  • Partial discharge diagnosis using VLF Sine wave, Damped AC or 50/60 Hz Slope technology voltages
  • Real-time data evaluation and display of results
  • PD and TD monitored withstand testing
