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 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...
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 ...

Our AHF's compensation capacity(ratio) can be set freely by the customers, to realize harmonics compensation, reactive power compensation or imbalance compensation. YT...
Passive Harmonic Filter The simplest of all filters are the ones built using just resistors, capacitors and inductors. Such filters are called passive harmoinc filters, as they are constructed from passive components. In electronics, passive components are those which do not produce energy of their own. They are only capable of dissipating energy (in the case of resistors) or storing energy (in th...
YTPQC-AHF Active Harmonic Filter is a comprehensive and flexible solution for power quality problems. It provides the advanced control and proven reliability that your facility needs to solve power quality issues. It monitors the load current and very quickly responds to the power system distortion as it develops. A corrective current is injected to effectively cancel out the harmonics required fr...
