The BAUR Viola TD is a high-performance VLF (Very Low Frequency) test system designed for comprehensive testing and diagnostics of medium-voltage cables and electrical equipment. It combines VLF withstand testing with tan delta (dissipation factor) measurement and Monitored Withstand Test (MWT), enabling accurate assessment of insulation condition, ageing, and moisture-related defects. Widely used in commissioning and maintenance, it helps prioritize cable replacement and prevent unexpected failures.
Technical Highlights: Max test voltage: up to ~44 kVrms / 60–62 kV peak | Frequency: typically 0.1 Hz (VLF truesinus®) | Voltage modes: VLF sine, rectangular, and DC | Tan delta accuracy: up to 1 × 10⁻⁴ | Supports MWT (combined withstand + tan δ diagnostics) | Suitable for MV cables up to 35 kV | Fully automated test sequences with USB data management | Compliant with IEEE 400.2, IEC 60060-3, IEC 60502.
Ideal for VLF withstand testing, insulation diagnostics, and condition-based maintenance of MV cable networks.
