In the optimal distribution module of reactive power, the device adopts Staitc Var Generator and TSC hybrid mode of reactive power compensation. SVG detects the reactive power of the system, controls the switching of capacitors, and determines the capacity and timing of its own reactive power generation. The capacity ratio of SVG and TSC can be configured; for applications with slow reactive power...
Power Quality Problems With the in-depth application of power electronic technology, the automation of the petrochemical industry has been continuously improved, and the nature of the load has also undergone qualitative changes. The increase of nonlinear and impact loads has brought about voltage flicker, three-phase imbalance, and excessive reactive power consumption. , harmonics and a series of ...
Power Quality Problems There are a large number of power electronic components in medical equipment. The more common equipment are MRI (nuclear magnetic resonance apparatus), CT machine, X-ray machine, DSA (cardiovascular imaging machine) and so on. Among them, MRI will generate radio frequency pulses and alternating magnetic fields to generate nuclear magnetic resonance, and radio frequency pulse...
Over its 100-year history, welding has become one of the most essential technical skills in manufacturing and fabrication. The process of using high-temperature, electrical-powered heat to fuse two pieces of metal or synthetic material has been incorporated throughout the industry in an increasingly wide variety of applications that rely on a range of tools and techniques. But Electrical welding m...
