Low Voltage Regulation


The low voltage regulation system LVRSys™ represents a cost effective alternative for grid expansion. The economic use is recommended in all low voltage grids where short-circuit power is sufficient, but have voltage maintenance problems..

Voltage stability problems can occur locally (in single lines) or at the level of the entire low voltage grid. LVRSys™ can be used with flexibility as line regulator or as direct regulator on the local grid station. .

Advantages LVRSys™:

Voltage regulation in local grids from 22 kVA to 630 kVA

For use as string regulator or as local grid regulator

Regulation range from ±6 % to ±20 % of the nominal voltage

Independent regulation of three-phases voltages

Optional power quality-analysis according to EN 50160 and IEC 61000-2-2


LVRSys™ 1-phase 7,5 kVA to 50 kVA

LVRSys™ adjustable transformer 22 kVA to 110 kVA

LVRSys™ 3-phase 22 kVA to 630 kVA
