Low Voltage Regulator

General

To face the challenge of global warming, all power utility shifted to seeking for increase renewable energy connect to Grid. Like distributed renewable energy is widely connected to LT side ,such like 0.4KV.

Upon more and more distributed renewable energy injection to LT line, those RE-energy not only booster LT and transformer voltage also reduce transformer receiving capacity.

SMICO Electric LSVR series voltage regulators are especially designed to regulation on-grid site voltage problem to increase transformer capacity to receiving more RE-energy.
