32-Step voltage regulator

Your position:Home > Main Products > 32-Step voltage regulator >
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 &current 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 charger with RVR controller sampling voltage and current data and on load tap charger steps from current transformer and voltage transformer and limit switches.


Best solution for your power!
