As the complexity of modern power systems continues to increase, power quality issues are becoming more serious, especially the harmonic pollution in power systems. Harmonics not only affect the normal operation of electrical equipment but can also lead to equipment damage and even increase energy consumption. To address this problem, the Energy-Saving Active Power Filter (APF) has emerged as an essential tool for improving power quality and enhancing system efficiency. The Shidifu brand's energy-saving active power filter stands out in this field and, through PROMAX ELECTRIC in Vietnam, serves as the exclusive distributor of this brand. It is widely used in industrial and commercial power systems, helping customers reduce energy costs and improve system stability.
Harmonics refer to the distortion of voltage or current waveforms in a power system, where the frequency of the waveform deviates from the fundamental frequency (such as 50Hz or 60Hz), generating fluctuations at multiples of the fundamental frequency. In other words, harmonics are signal components whose frequencies are integer multiples of the fundamental frequency, and they are generated by nonlinear loads. These harmonics can cause distortions in the voltage and current waveforms of the power system.
