The SVR line automatic voltage regulator is a device that ensures the stability of the output voltage by tracking the line voltage changes and automatically adjusting the transformation ratio of the device itself. It can automatically adjust the input voltage within the range of ±20%. It is especially suitable for lines with large voltage fluctuations or lines with large voltage drops. Install this feeder voltage regulator in series in the middle of 6kV, 10kV and 35kV lines. At the rear, the line voltage is adjusted within a certain range to ensure the user's power supply voltage and reduce the line loss of the line. In addition, the SVR feeder automatic voltage regulator is also suitable for substations where the main transformer does not have the ability to regulate voltage. This voltage regulator is installed on the outlet side of the transformer in the substation to ensure the bus voltage on the outlet side. It has a wide range of applications in the national rural power grid, urban power grid, oil field, coal, chemical industry, substation and other fields.
