SVR-3 type Three phase Automatic Step voltage regulator
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.
+High breaking capacity tap charger from self-developed technology, More reliable and more steps 2.5% each by Max 16 steps( totally 40%);
+With SVR type Smart controller, a self-developed technology, GPRS/GSM, Blue-tooth.
+With self-protection LOCK-OUT functions: Line fault, Overload, OverCurrent, Under-voltage
+With adjustable voltage datum and step scope limit, step draw delay, data setting.
