The VOTANO 100 is supplied with the separate OMICRON VBO1 Voltage Booster for VT Ratio and Phase Error. This 4 kV amplifier provides the necessary test voltage during the ratio measurement. VBO1 is positioned close to the transformer under test while VOTANO 100 is operated in the safe area outside of the high-voltage environment.
Features
VT ratio and phase error measurement in accordance with the standard:
- Primary voltage levels between 5 % and 190 % of the nominal primary voltage
- Nominal burden and burden values below (0 VA, 25 % and 100 % burden)
- Other windings under load and without load
Safety Testing:
- The software-guided measuring procedure via GUI or PC software gives you enhanced security
- Wiring diagrams for each single measurement are provided to support you
- Acoustic warnings sound during measurements with higher voltages
- There is a plausibility check before critical measurements
- VBO1 offers you additional safety circuitry through surge arrestors for the measuring channels
- The system performs an integrated check to ensure VBO1 is correctly grounded
- Emergency stop buttons give you the possibility of additional safety interruptions
