OMICRON’s VOTANO 100 is cited to be the first voltage transformer testing and calibration system to combine mobility (total weight less than 33 lbs.) with the highest level of accuracy (precise calibration of voltage transformers with class 0.1).
With its software-guided measurement, VOTANO 100 can test protection and metering voltage transformers in less than 20 minutes. In a single pass, winding resistance, short-circuit impedances, transformation ratio, and the magnetic characteristics curve of inductive and capacitive voltage transformers are determined. During this process, VOTANO 100 assesses voltage transformers with up to five secondary windings—for no-load and standard load operating conditions. The measured results are automatically assessed in accordance with international standards.
The VBO1 voltage booster comes with VOTANO 100. This amplifier supplies the primary side of the transformer with a maximum reference voltage of 4 kV for the transformation ratio measurement. The VBO1 is positioned near the test object, while the test engineer operates VOTANO 100 in a secure area outside of the high-voltage environment. The compact dimensions and low weight guarantee easy and convenient transport. The combined total weight of both devices is less than 33 lbs.
