SVR-3 type Three phase Automatic Step voltage regulator

General

The SVR-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.

So This SVR is eqv. 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.
