SVR Automatic Voltage Regulator (full name: Feeder Automatic Voltage Regulator) is an automatic voltage regulating device connected in series in 6kV, 10kV or 35kV power lines. It can automatically track line voltage fluctuations and adjust its own transformation ratio to ensure the output voltage remains stable within the acceptable range. It is widely applicable to the following scenarios:
1.Rural Power Grids: Lines with long power supply radii, dispersed loads, and significant seasonal voltage fluctuations.
2.Urban Distribution Networks: Feeders with rapid load growth and severe voltage drops.
3.Industrial and Mining Enterprises: Locations with long power supply lines and large voltage drops, such as oil fields and coal mines.
4.Temporary Solutions: An economical and effective means to improve voltage quality when conditions for building a new substation are not yet mature.
