SET DVR – Dynamic Voltage Restorer For Critical Industrial Processes

AVC SET DVR is an innovating system designed to mitigate and eliminate the effect of electrical disturbances on critical industrial processes through the elimination of sags and transitory overvoltages. Power generation, transport and distribution systems are limited and their problems can affect production processes as well as to produce economic consequences.

It is composed of a transformer, reversible rectifier assembly plus an inverter, the purpose of which is to compensate for voltage disturbances and imbalances and regulate them in the event of voltage fluctuations and surges. The system also monitors and controls the events that occur.

Advantages

High Performance

  • Continuous regulation to provide a high degree of stabilisation (±0.5%)
  • Mitigates three-phase voltage gaps up to 70% in depth or single-phase interruptions
  • Compensates for voltage dips even for long periods (up to 30 sec)
  • Independent compensation by phase
  • Response time less than 3 msec
  • Very high-performance power supply systems >98.5%

Flexibility

  • Wide range of powers from 30 to 6 MVA
  • Easy to adapt to any network voltage
  • Compatible with all existing protection systems
  • Turnkey project in accordance with the technical requirements of the client’s facilities.
  • Easy to connect up to 3 units in parallel

Strenght

  • Automatic bypass to maintain output voltage
  • DSP digital control system
  • Withstands 150% overloads for 1 sec
  • Energy flow in both directions

Easy to Maintain

  • Does not require batteries or other energy storage components
  • Modular design that facilitates maintenance and repairs
