DVR is cost-effective and efficiently protects sensitive loads in power distribution and transmission systems against voltage distortions. It is primarily designed to reduce voltage sags on power lines that cater to sensitive commercial and industrial equipment's.
The DVR system consists of a transformer, a reversible rectifier, and an inverter with three modes of operation (Normal Mode, Static Bypass Mode, and Manual Bypass Mode) to meet the requirements of industrial production processes, maintain a stable and constant output voltage regardless of changes in input voltage as defined in the operation limits.
It is designed not only to eliminate voltage sags and it also helps in mitigating other energy quality problems at the same time, such as: fluctuations, flicker effects, overvoltage, and voltage unbalance.
