传统无源滤波器只能滤除有限次谐波,对其他次谐波甚至有放大作用，难以应对电网谐波多变的特征，有潜在的谐据风险。WEAF系列低压有源滤波器是我司自主研制推出的全数字消谐设备，与传统技术相比具有特殊优势，更快、更小、功能更强且安装方便、调试简单维护方便，这些优势使其能轻松解决电能质量问题。该产品除可以动态补偿谐波外，还可以进行无功功率补偿、解决电压波动及闪变等电能质量问题，同时该系列产品采用最先进的控制技术，实现全自动化控制，是目前消除谐波的最佳设备。

The traditional passive filter can only filter out the limited harmonicand even amplify the other harmonic, which is difficult to deal withthe characteristies of harmonic change in the power grid, and haspolential resonance risk, WEAF series low vollage active power fileris our independent research and development of the full digitaldetuning equipment, compared with the tradilional technelogy has aspecial advantage, faster, smaller, more powerlul and easy to inslal easy to debug and easy fo maintain, these advanlages make it easylo solve power guality problems. In addition to dynamic harmoniccompensafion, the product can also carry out reactive powercompensalion, to solve voltage fluctualions and ficker and otherpower qualily problems, while the series of producls using the mostadvanced conirol technology, fully automated control, is currentlythe best eauipment io eliminate harmonies.
