The RVR-1 type feeder automatic voltage regulator is actually a single phase oil immersed auto-transformer with RVR controller and gathering sampling of voltage ¤t signal, on load tap charger controlling device to achieve gird more efficient from adjust the load character by increase and decrease the voltage. So This RVR is a transformer equipped with on load tap changer with RVR controller sampling voltage and current data and on load tap charger steps from current transformer and voltage transformer and limit switches.
