viola | viola TD VLF testing and diagnostics unit

The portable BAUR viola and viola TD devices are used for
– Testing medium-voltage cables and electrical equipment (generators, transformers and switchgear);
– Cable sheath testing;
– Cable diagnostics (viola 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*.
* in combination with the BAUR PD-TaD 62 PD diagnostics system.

Manufactory: BAUR (Austria).
