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...
Does Active Harmonic Filter can saving energy? YTPQC-AHF Active Harmonic Filter can save energy by reducing the amount of harmonic distortion in a power system. Harmonic distortion can cause power losses and reduce the efficiency of electrical equipment, so reducing it can help to save energy. How does active harmonic filter save energy？ YTPQC-AHF Active Harmonic filters can save energy by ...
What is the power quality problems at sites with welding machines? The most common power quality problems associated with welding machines are voltage sags, harmonic pollution, and electromagnetic interference. Voltage sags can cause the welding machine to operate at a lower than expected output, resulting in poor weld quality. Harmonic distortion pollution can cause interference with other equipm...
What is difference between THD and TDD? While power electronics have created considerable energy savings, they can distort the quality of electrical power delivered through the building they serve, reducing the effectiveness and life span of the power electronics contained within that building. THD is described as the instantaneous value of the ratio of the root-mean-square (rms) of the harmonic c...
What are scenarios causing power factor displacements 1. Poorly designed electrical systems with inadequate power factor correction equipment. 2. Large inductive loads such as motors, transformers, and generators that cause lagging power factor. 3. Unbalanced three-phase loads that cause phase displacement of the current and voltage waveforms. 4. Unbalanced single-phase loads that cause current an...
Reactive currents backstreaming from Solar to Utility Reactive currents backstreaming(from Solar plant) in power supply system is not only harmful but also expensive for financial purposes. Parasite currents in both electricity transmission lines and equipment of solar power-stations cause financial losses because of converting electric energy to thermal (thus making generation amount lower, that ...
Power Quality Power electronics make modern life possible and enable all other areas of innovation. Although stable power delivery seems like a simple problem, the design of a high-efficiency power transmission and conversion system is prone to several problems that reduce efficiency by reducing delivered power. Nonlinear components are needed in power electronics to control the flow of power and ...
