KLD-AMS Series Active Filter

PRODUCT OVERVIEW

With the progress of science and technology, more and more power electronic devices and other non-linear loads are applied in companies, such as rectifiers, inverters, UPS, elevators, air conditioners, energy-saving lights, computers, household appliances, etc. These nonlinear loads generate a large amount of harmonic currents that are being injected into the power grid, leading to the voltage waveform distortion. This voltage harmonic pollution can cause serious harm to the grid and all back-end users. In addition, impacting and fluctuating loads, e.g., arc furnace welding equipment, not only generates a large amount of high harmonics in operation, but also causes voltage fluctuations, flickers and three-phase imbalance and other power quality problems, threatening the safe operation of the grid. Harmonics is virtually a kind of interference that "pollutes" the power grid.

KLD-AMS series active power filters are connected in parallel with the harmonic source. It quickly generates currents that are equal in size and opposite in direction to offset the harmonic currents produced by the harmonic source loads through real-time detection and tracking, thus eliminating harmonics and avoiding distortion of system voltage and current waveforms. The equippment has an adaptive function to compensate for harmonics of varying frequency and size, and quickly responds to the compensation object.
