Voltage transformer testing, calibration and assessment
How VOTANO 100 works
Uses a well-established, model-based testing method
The method can be compared to that used by OMICRON’s CT Analyzer
Injects low test signals into the secondary side of a VT/CVT
Determines a VT’s/CVT’s equivalent circuit parameters
Identifies all relevant VT/CVT performance parameters
Displays all relevant VT/CVT parameters and its accuracy at different currents and burdens and with loaded and unloaded secondary windings
Evaluates the VT/CVT according to the selected standard
Sophisticated testing of inductive and capacitive voltage transformers
VOTANO 100 is the first portable device (15 kg/33 lbs) which offers highly accurate voltage transformer tests. This allows to use VOTANO 100 not only for electrical performance checks, but also for class verification and calibration.
It performs quick tests of all kinds of inductive voltage transformers (VTs) and capacitive voltage transformers (CVTs) for both protection and metering purposes. Its light-weight design makes it ideal for on-site tests and calibration tasks in power system grids. As a manufacturer or testing lab you can use VOTANO 100 in your production facilities and test/development labs.
The voltage booster VBO2 provides the test voltage during the ratio measurement. Its integrated switchbox automatically switches between the necessary test sequences.
