Filter reactors DIN VDE 0550/0532 for general applications Application Harmonics generated by non-linear loads such as variable speed drives or other static power conversion equipment have grown rapidly in recent years. Harmonic currents and the voltage distortion, created by these currents have devastating effects on power supply and distribution systems and its connected loads. This can result in failure of power factor correction capacitors due to overloading, system resonance, overheating of cables and transformers as well as misoperation of PLC’s, computer and other sensitive...

Power Factor Controller BLR-CX Edition2 Reactive power compensation panels are used to reduce load in the electrical grid and to save costs. This is the reason, that there are special requirements for the control units of these compensation panels, the reactive power regulator. The most important task for the reactive power regulator is to control the reliable termination of reactive power. This is reducing the costs for electrical energy. Cables, transformers, switch components and power distribution are unloaded by reduce reactive power. Another task of the reactive power regulator is...
