Product Description
SVR line automatic voltage regulator is a device that ensures stable output voltage by tracking changes in line voltage and automatically adjusting the ratio of the device body. The input voltage can be automatically adjusted within the range of -20% -+10%. It is particularly suitable for lines with high voltage fluctuations or voltage drops. This type of feeder voltage regulator is installed in series at the middle and rear of 6kV, 10kV, and 35kV lines, and the line voltage can be adjusted within a certain range to ensure the user's power supply voltage and reduce line losses. In addition, the FSVR feeder automatic voltage regulator is also suitable for substations where the main transformer does not have voltage regulation capability. This type of voltage regulator is installed on the outlet side of the substation transformer to ensure the voltage of the busbar on the outlet side. It is widely used in fields such as rural power grid, urban power grid, oil field, coal, chemical industry, substation, etc. across the country.
