ZGR - Model AVC DVR -Dynamic Voltage Restorer

FromZGR Corporation

SHARE

The ZGR AVC DVR is a state-of-the-art dynamic voltage restorer aimed at ensuring the seamless operation of industrial processes by addressing and compensating voltage sags and other electrical disturbances. This system combines a transformer, a bidirectional rectifier unit, and an inverter to maintain a consistent and stable output voltage, irrespective of variations in the grid voltage. It effectively mitigates disturbances, balances voltages, and regulates fluctuations and overvoltages. Additionally, the ZGR AVC DVR is equipped with a monitoring system that controls and records events, which can be reviewed via its touch control panel. This ensures that industrial processes remain uninterrupted and that the quality of the electrical grid meets the stringent demands of industrial production. The system is built to be robust and reliable, providing hybrid solutions that cater to a range of industrial needs.

ZGR AVC DVR is an innovative system of compensation of voltage sags for the continuity of industrial processes.

ZGR AVC 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 a continuous regulation for minor disturbances.

ZGR AVC DVR guarantees the quality of the grid meeting the demands of industrial production processes while keeping stable and constant the output voltage regardless of energy grid voltage variations.

It consists of a transformer, a bidirectional recti!er unit, plus an inverter. The aim of the ZGR AVC DVR is to compensate disturbances, unbalanced voltages, and to regulate them in case of possible “uctuations and overvoltages.

Moreover, ZGR AVC DVR monitors, controls and records events that occur in the system, allowing subsequent viewing through the touch control panel.
