Protection against instable Mains Supply

A key criterion for the operational safety of industrial facilities is the optimum power supply. However, there is always the risk of unavoidable over- and under-voltages due to connection or disconnection of enormous loads or lightning. Such fluctuations may endanger the power supply of the plant, which may lead to a standstill of production and high costs. RPT Ruhstrat Power Technology offers a solution against such voltage instability in the mains supply: the Online Voltage Regulation System, in short: OLIVER

OLIVER is a 3-phase active voltage regulator for highly dynamic correction of symmetrical and unsymmetrical voltage dips and / or phase imbalances in the electrical power supply. OLIVER reliably compensates over- and under-voltages up to 40 %. OLIVER stabilizes the network extremely fast and is easily integrated in the respective industrial setting.
