Voltage stabilizers are used for stabilization of large and long-term voltage fluctuations. Here the grid type is not important. For three-phase systems without neutral conductor a neutral earthing transformer is built in, which admits unbalanced load up to 30 %. If the voltage fluctuations for three-phase systems are too unequal in the single phases, or if the loads on the three phases are divided very unevenly, we recommend separate variable transformers for the stabilization of each phase. In case of relatively even fluctuations, a variable transformer with only one drive may be sufficient.
- Power range up to 1,600 kVA
- Stabilization of voltage fluctuations up to +/- 30 %
- Control rate 40V/s
