Product Details

RVR-3 type feeder automatic step voltage regulator

The RVR-3 type feeder automatic step voltage regulator is actually a three phase oil immersed auto-transformer with SVR controller and gathering sampling of voltage 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 equivalent to a transformer equipped with on load tap charger with SVR controller sampling voltage and current data and on load tap charger steps from current transformer and voltage transformer and limit switches.- The RVR-3 type feeder automatic step voltage regulator is actually a three phase oil immersed auto-transformer with SVR 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.
