Product description
FSVR line automatic voltage regulator is a device that tracks the line voltage change and automatically adjusts the transformation ratio of the device to ensure the stable output voltage. The input voltage can be automatically adjusted in the range of -20% to +10%. It is especially suitable for lines with large voltage fluctuations or lines with large voltage drops. This feeder voltage regulator is installed in series at 6kV, 10kV, In the middle and rear part of the 35kV line, 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 FSVR feeder automatic voltage regulator is also suitable for substations where the main transformer does not have the ability to adjust voltage. Install this type of voltage regulator on the outlet side of the substation transformer to ensure the bus voltage on the outlet side. It is widely used in the national rural power grid, urban power grid, oil field, coal, chemical industry, substation and other fields.
