BAUR Viola TD - VLF Cable Test and Diagnostics System
The Baur Viola TD is an advanced Very Low Frequency (VLF) test system engineered for thorough testing and diagnostics of medium-voltage (MV) cables and electrical equipment. This device integrates VLF withstand testing with tan delta (dissipation factor) measurement and Monitored Withstand Test (MWT), providing precise evaluation of insulation conditions, aging, and moisture-related defects to help ensure network reliability.
Features & Benefits
- Maximum test voltage of up to approximately 44 kVrms / 60–62 kV peak for robust insulation testing.
- Operates at a frequency of typically 0.1 Hz using VLF truesinus® technology for accurate results.
- Supports multiple voltage modes including VLF sine, rectangular waveforms, and DC testing.
- Highly precise tan delta measurement with accuracy up to 1 × 10⁻⁴ for sensitive insulation diagnostics.
- Incorporates Monitored Withstand Test (MWT) combining withstand voltage and tan delta diagnostics.
- Compatible for MV cables up to 35 kV, suitable for commissioning and maintenance tasks.
- Fully automated test sequences with USB data management enable efficient workflow and data handling.
- Compliant with international standards IEEE 400.2, IEC 60060-3, and IEC 60502 ensuring reliable and accepted test procedures.
Material & Build
The system is built with rugged, precision electronic components designed for field and lab use. Its robust enclosure protects delicate instrumentation to maintain accuracy over time, while its user-friendly interfaces simplify operation even in challenging environments.
