Description

SVR-3 type feeder 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.

Main features of Three phase step voltage regulator

+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.
