The Active Harmonic Filter adopts advanced power electronics technology to detect the harmonics in the grid in real time, generate the reverse phase compensation current through the converter, and dynamically filter out the harmonics in the grid.Static Var Generator can be real-time dynamic compensation, can compensate for the perceptual reactive power and the tolerance of the reactive p...
Introduction of YT APF YT Active Power Filter(APF) is connected in parallel with the power grid, which detects the harmonics in the power grid in real time, generates an inverse compensation current through the converter, and dynamically filters out the harmonics in the power grid. Its operation is not affected by the grid structure and load type, and will not resonate with the system, which perfe...
Characteristics of reactive energy Reactive energy is not consumed, it is not useful for the system. Although it does not produce useful work, it is necessary to neutralize or compensate it. The reactive energy is measured in kVArh (Kilo volt-amp reactive hour). Reactive energy is created in devices or machinery that works with motors or transformers powered by the alternating current that reaches...

YTPQC-AHF Active Harmonic Filters(AHF) provide a fast return on your investment(ROI). The quick and effective response of Merus Active Harmonic Filters to power system variations enables higher process reliability, longer equipment life, reduced energy los...
Background The input terminals of switching power supply and ups of Chinatelecom cloud computing Guizhou Information Park data center generate harmonic current, and the final harmonic current is collected on the general busbar. A large amount of harmonic current will cause the following harm to the communication room. Harmonic current will interfere with the communication signals of adjacent condu...
Power Quality Problems in Data Center Due to the uninterrupted power supply of the load in the data center room, a large number of UPS, switching power supplies and inverter air conditioners are used. The input stages of these devices are all three-phase arrangements, which generate a lot of harmonics when used. The switching power supply and UPS equipment first rectify the AC into DC, and then co...
Due to the rapid development of power electronic technology, the nonlinear characteristics of industrial and agricultural power loads, especially transportation and civil electrical products are becoming more and more serious, and the power factor of users is also declining. Therefore, reactive power compensation devices are more and more widely used. The power compensation device is used to suppl...
Three-phase lines are common: three-phase three wire, three-phase four wire The three - phase three - wire system is star connection neutral point ungrounded and Angle connection method, the general high - voltage power supply uses three - phase three - wire system, three - phase four - wire is star connection neutral point grounding, low - voltage system uses three - phase four - wire system. &nb...
