APF Series of Active Power Filter Overview APF Series of Active Power Filter uses DSP digital signal processor to Analyse magnitude and phase of Harmonics in voltage and current on the grid with DQ transformation, with full response of 30ms, which is faster than equivalent APF from most competitors. APF Series of Active Power Filter is able to compensate in reactive power when its maximum capacity is not meet for filtering. We recommanded Using APF alone if the Current distortion is serious and rich in spectrum, while the fundamental current phase shift ignorable. But for most users' the two factors listed above is not ignorable, so We recommend Using APF with LFPC. While LFPC filter some fixed large-in-magnitude harmonics, while APF can save its capacity for higher order harmonics, thus saving investment in equipment without compromising filtering effect. Implementation and reference standard IEEE 519 IEC 61642 IEC 61000-2-4 GB 7251-97 GB/T 16935.1-1997 GB 14048.3-93 GB/T 3859.1-93 GB 50052-95 GB 50054-95 GB/T 12325-2003 GB 12326-2000 GB/T 14549-93 GB/T 15945-1995 Main technical performance
