The BAUR VIOLA TD is a portable medium voltage cable testing and diagnostic device that combines VLF (Very Low Frequency) testing capabilities with integrated dissipation factor (tan δ) measurement and monitored withstand voltage testsMonitored Withstand Test – MWT). This combination allows both the insulation test and the diagnosis of the condition of the dielectric material in cables and sheaths up to 35 kV to be carried out automatically and non-destructively, providing a complete assessment of the insulation condition without the need for additional equipment. The VIOLA TD uses VLF truesinus® voltage technology to generate reproducible high test voltages with low distortion, and automatic sequences that simplify test setup, reduce testing time, and improve result consistency.
Frequently Asked Questions
¿Qué funciones integra el BAUR VIOLA TD?
The VIOLA TD combines three key capabilities in a single device: VLF (Very Low Frequency) testing of medium-voltage insulated cables, dissipation factor (tan δ) diagnostics, and Monitored Withstand Test, providing a comprehensive assessment of the cable insulation condition.
What advantages does VLF truesinus® technology offer in measurements?
VLF truesinus® technology generates a low-frequency sinusoidal voltage waveform with minimal distortion, allowing a high, reproducible test voltage that is independent of the load, ideal for testing medium-voltage cables without subjecting them to disturbing voltages or damaging the insulation.
What voltage range and wires does the VIOLA TD support?
The equipment is suitable for testing medium-voltage electrical cables and cable coverings up to 35 kV, with a maximum test voltage of approximately 44 kV rms (62 kV peak), allowing for the evaluation of both cables and insulating materials in a wide range of applications.
How does the use of the damping factor improve isolation diagnosis?
The measurement of dissipation factor (tan δ) provides information about the physical condition and aging of the dielectric insulation, since higher values indicate greater dielectric losses, moisture, or other defects. Integrating this measurement with the voltage test in a single test cycle allows for a more precise and comprehensive assessment of the cable condition.
What benefits do automated test and diagnostic sequences offer?
The automatic sequences of the VIOLA TD speed up test execution, reduce the risk of human errors, and standardize testing and diagnostic procedures, which simplifies field operation, improves result consistency, and facilitates comparison between repeated measurements over time.
