OMICRON VOTANO 100 Voltage transformer testing, calibration and assessment

Fast short test duration


Available on back-order

VOTANO 100 is the first portable device (33 pounds) that allows you to test inductive voltage transformers (VTs) and capacitive voltage transformers (CVTs) for both protection and metering purposes. It performs quick tests of all kinds of voltage transformers in power system grids. As a manufacturer or testing lab, you can use VOTANO 100 in your production facilities and test/development labs. VOTANO 100 comes with the separate voltage booster VBO2, which provides the necessary test voltage during ratio measurements. Its integrated switchbox automatically switches between different test sequences.
