 Medium Voltage Active Voltage Conditioner
The Active Voltage conditioner (AVC) can be applied at Medium Voltage(MV) from 1kV up to 36kV with loads from 1 MVA to 50MVA. It can be applied to a complete facility or to part of a facility network or to a specific critical MV load. High efficiency >98% High power voltage conditioning No Storage - No fault contribution
- Able to correct for multiple sequential sags as there is no recharge time
- No resonance with system capacitors
- Does not saturate downstream distribution transformers
Continuous correction of: - 10% under-voltage—protection from utility voltage reductions
- Voltage balance
- Voltage flicker
- Voltage harmonics - see details
- 30 seconds (not cycles) correction of:
- Up to 50% 3-phase voltage sags
- Up to 83% 1-phase voltage sags
Other features: - Outdoor enclosure, for all environments
- Easy 3-wire in 3-wire out installation
- Facility wide or load dedicated solutions.
- It is usually more economical to focus on dedicated loads if total critical load to be protected is less than 80% of total plant load.

AVC Selection Guide Back to Omniverter AVC overview Transmission Line Event @ 69kV seen at 26.4kV loadTransmission line fault reflected through 26.4 kV utility distribution system would have caused production stoppage with 1 phase down to 58% of nominal voltage. The Active Voltage Conditioner protected the facility providing output voltages > 96% so no production interruption occurred.
 Distribution Line Event at 26.4 kVA two phase sag on the utility distribution system caused two of the three phases to drop below 80% of nominal for 1 second which would have caused production in the facility to stop. The AVC at 26.4 kV corrected Line to Line Voltages to nominal—no loads were dropped during voltage sag and production continued without any problem.
