DYNAMIC VOLTAGE RESTORER FELDVR

• FELDVR dynamic voltage restorer is a voltage compensation device designed for voltage sag (oscillation) control. It mainly consists of bypass contactors, series thyristors, inverters, and supercapacitors. By utilizing the fast charging and discharging advantages of supercapacitors, it can instantly compensate for rapidly falling voltages and ensure that the load voltage remains stable in a normal state. Effectively ensuring the safe and stable operation of the load, avoiding significant losses to customers caused by voltage dips.
  Over 85% of the power quality problems which afflict modern precision manufacturing industry come from transient voltage disturbances that brings more and more damage on products and cause production interruption In the process of strategic transformation of manufacturing industry from scale and artificiality to precision and intelligence.Even in our daily life, a transient voltage disturbance will cause a serial dangerous potential and unpleasant feeling, such as the escalator
  shutdown, medical inspection instrument shut down,It is attracting increasing attention.These factors that cause voltage disturbances are complex, random, unpredictable and unavoidable.They may originate from the grid side, the user side, natural factors, or human factors. But voltage disturbances can be completely controlled!
