Viola TD high-voltage VLF installation - BAUR
High-voltage installation for testing 6-35 kV cables with cross-linked polyethylene insulation with voltages up to 60 kV at a frequency of 0.1 Hz and diagnostics by measuring the dielectric loss tangent.The high-voltage portable two-module VLF installation VIOLA is designed for:
- testing cables with cross-linked polyethylene insulation 6-35 kV with alternating voltage with a frequency of 0.1 Hz
- diagnostics of cables by measuring the dielectric loss tangent
- testing of cables with paper-oil insulation 6-10 kV with direct voltage up to 60 kV
- tests of cable sheaths with direct voltage up to 10 kV
- searching for damage to the cable sheath using the step voltage method together with a galvanometer.
The unit is easy to use: portable (thanks to its two-module design) and easy to connect. Tests can be carried out manually or fully automatically. The navigation menu on the built-in display is intuitive and fully Russified.
Diagnostics by measuring the dielectric loss tangent of cables allows you to quickly and reliably assess aging and deterioration of cable insulation. The installation contains testing methods in accordance with the latest foreign standards, allowing this diagnostic to be carried out automatically with the issuance of a clear and complete test report.
The installation can be used as a high voltage source when measuring partial discharges in a cable. It also becomes possible to use the MWT (Full Monitored Withstand Test) mode, which reduces cable testing time by simultaneously measuring loss tangent and/or partial discharges, thereby reducing the time stress on the cable with increased voltage.
Functional features of VIOLA:
- TrueSinus technology – pure sine wave regardless of load
- Automatic testing and diagnostic methods according to standards
- Maximum insulation capacitance up to 10 µF
- Fully automated, programmable test sequence
- Data transfer and storage via USB interface
- Short circuit protection
- Ease of transportation (two-module design)
- Diagnostic Reporter – application for processing and evaluating test reports
- Included in the State Register of Measuring Instruments of the Russian Federation
